When Should You Trust Your Gut? | Dalton & Michael Podcast

April 22, 2024
Episode Summary
In the podcast episode "When Should You Trust Your Gut," Dalton Post-Michael discusses the nuanced advice necessary for startup founders at different stages of expertise and idea development. He outlines two common scenarios encountered at Y Combinator (YC): experienced founders who have developed a valuable tool within a company and want to productize it, and young, technically skilled individuals eager to start a business but unsure of what to focus on. Dalton emphasizes that generic advice does not suffice; instead, tailored guidance based on the founder's background and knowledge is crucial. Dalton elaborates on the concept of trusting one's gut, contrasting it with the extreme of seeking constant external validation. He uses the example of Steve Jobs, who famously relied on his vision and instincts rather than customer feedback, to illustrate the potential success of trusting one's gut when one has a clear and innovative vision. Conversely, he mentions the "mom test" as an extreme of relying solely on external input, which can lead to a lack of originality and personal investment in the idea. The discussion then shifts to practical advice for founders. For those with significant experience and a proven track record, such as having developed a widely used tool within a company, Dalton suggests that trusting their gut and leveraging their deep understanding and instincts can be advantageous. They likely have valuable insights into the needs and gaps in the market that less experienced individuals might not see. On the other hand, founders without deep industry knowledge or a clear vision should be more cautious about trusting their instincts. They should focus more on learning from potential customers and the market to build their expertise. Dalton and Michael conclude by discussing the importance of recognizing whether one is bringing expertise to a startup or needs to build it from the ground up. They advise that founders with deep knowledge should trust their instincts more, while those still acquiring knowledge should adopt a more open and exploratory approach. This tailored strategy ensures that founders can navigate the startup landscape more effectively, making informed decisions that align with their level of experience and understanding of the industry.

Building Confidence In Yourself and Your Ideas | Dalton & Michael Podcast

March 20, 2024
Episode Summary
In the episode titled "Building Confidence In Yourself and Your Ideas" from the Dalton & Michael Podcast, the hosts delve into the common pitfalls that startups and founders face when trying to validate their business ideas and the importance of building conviction in their ventures. They begin by sharing a story about a YC company that decided to pivot after minimal effort in validating their idea, highlighting the low level of effort and lack of rigorous thinking that often plagues startups. The hosts argue that many founders, especially those trained as Product Managers (PMs) or in user research, struggle with selling their products because their skills are not directly transferable to acquiring first customers. The discussion then shifts to the concept of building conviction and how founders often pivot too quickly without fully understanding or believing in their own ideas. The hosts emphasize that the most important customer is oneself, and founders need to convince themselves that their idea is worth pursuing. They also touch on the importance of founder personality traits, particularly the ability to maintain high conviction despite challenges. The episode further explores the detrimental effects of fear on decision-making and the tendency of founders to rely on superficial validation methods, such as cold emailing or basing decisions on anecdotal evidence from social media. The hosts criticize the practice of pivoting based on insufficient data or feedback, referring to it as "pivotitis" and comparing it to a random walk that leads nowhere. They advocate for a more thoughtful approach to pivoting, where decisions are based on knowledge and a clear direction. Lastly, the hosts discuss the concept of a Minimum Viable Product (MVP) and the importance of creating a product that at least the founders themselves would want to use. They argue that many startups fail to achieve even this basic step, leading to wasted time and effort. The episode concludes with advice for founders to set realistic expectations, avoid fear-driven decisions, solve their own problems first, and ensure that their efforts are akin to a "good rep" in exercise, focusing on form and learning rather than quick, unfounded pivots.

Stop Innovating (On The Wrong Things)

March 15, 2024
Episode Summary
In the episode titled "Stop Innovating (On The Wrong Things)" from the podcast Dalton plus Michael, the hosts delve into the common pitfalls that entrepreneurs and startups face when they misdirect their innovative efforts. They begin by setting the stage in what they describe as the "innovation economy," where there's a prevalent belief among founders that innovation should be applied to every aspect of their business. This approach, however, is critiqued as spreading "innovation juice" too thinly across various problems, rather than focusing it where it's most needed. The hosts argue that the core miracle of a startup is finding product-market fit and creating something that people genuinely want. They caution against attempting to perform multiple "miracles" simultaneously, as this significantly lowers the chances of success. Instead, they advocate for concentrating innovation on solving real customer problems and adhering to best practices in other areas of the business. The discussion highlights how some founders get sidetracked by less relevant innovations, such as unconventional corporate structures or attempting to disprove established startup advice, which often does not serve the customer's interests. Specific examples of misguided innovation efforts include choosing unusual legal incorporations, like a Wyoming LLC instead of a Delaware C Corp, or making high-risk technology choices that complicate the business unnecessarily. The hosts also criticize the tendency to innovate in areas like business model and pricing in ways that confuse customers, emphasizing that clarity and familiarity can be more beneficial. The episode concludes with a broader reflection on the sources of advice that founders might follow, cautioning against applying principles from the branding world directly to technology startups. They suggest that successful tech companies often build on what's already proven to work, making incremental rather than radical changes. The overarching message is to prioritize the customer's needs and to save the more experimental innovations for after establishing a successful first venture.

Stop Innovating (On The Wrong Things) | Dalton & Michael Podcast

March 15, 2024
Episode Summary
In the episode titled "Stop Innovating (On The Wrong Things)" from the Dalton & Michael Podcast, the hosts delve into the common pitfalls that entrepreneurs and startups face when they misdirect their innovative efforts. The discussion begins with an observation of the current innovation economy, where there's a tendency among founders to spread their "innovation juice" across every problem they encounter, despite the finite amount of innovative energy a company can possess. The hosts argue that this approach often leads to innovating on the wrong aspects of a business, diverting focus from the core product or service that needs attention. The conversation highlights the miraculous nature of achieving product-market fit and the unlikelihood of replicating such success across multiple fronts simultaneously. The hosts emphasize the importance of concentrating innovation on solving real customer problems rather than getting distracted by less critical, innovative endeavors. They critique the tendency of some founders to prioritize personal preferences or contrarian bets over what is genuinely beneficial for the customer, pointing out that business should fundamentally be about serving the customer's needs. Specific examples of misguided innovation efforts discussed include unnecessary complications in corporate governance, such as choosing unconventional incorporation structures, and the pursuit of proving startup advice wrong as a principle. The hosts also touch on the folly of adopting idiosyncratic technology choices for the sake of novelty, using examples like startups that choose to write their own programming languages or adopt high-risk tech stacks without clear benefits to the product or service being offered. Moreover, the episode addresses the issue of startups complicating their business models and pricing strategies in an attempt to differentiate from competitors like AWS, only to confuse and alienate potential customers. The hosts argue that such innovations do not put the customer first and can hinder a startup's success. In conclusion, the podcast episode "Stop Innovating (On The Wrong Things)" serves as a cautionary tale for startups and entrepreneurs, urging them to focus their innovative efforts on what truly matters: creating a product or service that meets customer needs. The hosts advocate for adopting best practices in areas outside the startup's core innovation to avoid unnecessary risks and complications, suggesting that founders should save their more experimental ideas for future ventures once they have achieved success with their initial startup.

Apple Vision Pro: Startup Platform Of The Future?

February 28, 2024
Episode Summary
In the episode titled "Apple Vision Pro Startup Platform Of The Future" from The Light Cone podcast, the discussion centers around the implications of Apple's Vision Pro for startups and the broader tech ecosystem. The episode features Diana, a group partner at Y Combinator with a decade of experience in AR and VR, including a pioneering startup in the space, Escher Reality, which was acquired by Niantic. The conversation delves into the technical challenges and innovations behind augmented reality (AR) and virtual reality (VR), highlighting the Vision Pro's hardware and software advancements. Apple's approach, leveraging a pass-through video feed rather than an optical system for AR, simplifies some of the technical hurdles, enabling more immersive experiences.

This shift could pave the way for a new ecosystem of applications and interactions, much like the iPhone did for mobile apps. The discussion also touches on the importance of developers embracing this new platform, despite the initial challenges and uncertainties in adoption rates and market impact. Comparisons are drawn between the Vision Pro's launch and historical tech milestones, such as the iPhone and Tesla's product strategy, to speculate on the device's potential to be a transformative platform. The conversation concludes with insights into how startups and developers might navigate this emerging space, emphasizing the importance of genuine enthusiasm and innovation in creating applications that leverage the unique capabilities of AR and VR technologies. The episode suggests that while the path may be uncertain, the Vision Pro offers a fertile ground for the development of groundbreaking applications and experiences.

Should Your Startup Bootstrap or Raise Venture Capital?

February 13, 2024
Episode Summary
The hosts start by clarifying that the vast majority of businesses should not and do not raise venture capital. Venture capital is meant for investing in companies that have the potential to grow exponentially in value, providing a large return for investors. Most businesses do not fall into this category. Even many software companies should not raise VC funding. The numbers show that only a very small percentage of all businesses started receive VC backing. They go on to explain that the whole debate around bootstrapping versus raising VC is somewhat manufactured. Very few people actually believe it is inherently better to start a VC-backed business. Raising VC funding is very difficult and not a reliable path to getting rich. Most wealthy people made their money in other ways like real estate, medicine, law, etc. Also, no one is forced into starting a VC-backed business. You can always choose to bootstrap initially and potentially raise VC later on if there is demand from investors. A key point they make is that no major trillion-dollar software company has ever been fully bootstrapped. So while you may be able to build a very successful business without VC funding, the track record shows you likely cannot build one of the most massive companies without that outside investment. They wrap up by clarifying that their argument is not against bootstrapping, which can absolutely be a great path. They just want founders to have realistic expectations about the pros and cons of both approaches. Raising venture capital enables some companies to exist that otherwise would likely not be possible. But it also comes with many downsides that founders should fully consider before deciding if it's the right path.

The Truth About Building AI Startups Today

February 9, 2024
Episode Summary
The Light Cone podcast episode explores the current state of AI startups. The hosts - Gary, Jared, Harj and Diana - are Y Combinator group partners who work with AI founders. They explain why so many of their recent batch companies utilize large language models (LLMs). Rather than YC seeking out AI startups, ambitious founders are choosing to build companies using this new technology. Many observers dismiss these startups as mere "GPT wrappers", but the hosts push back on that characterization. Well-designed user experiences still matter, even when leveraging LLMs under the hood. The best ideas solve specific problems with customized data and business logic, not just generic automations. As examples, they discuss startups parsing government contracts, improving sales workflows, and streamlining regulatory compliance. The hosts explore other promising spaces like data privacy tools for enterprises sharing sensitive data with LLMs. They also examine the tradeoffs between general foundation models versus custom trained models tailored to niche use cases. Overall there is a proliferation of new ideas to build companies thanks to recent advances in AI. However, the hosts warn entrepreneurs to avoid "AI tar pits" - ideas that sound exciting but have little actual product-market fit. The AI copilot concept draws interest but many customers struggle to find practical uses. Broad promises to fine-tune open source models also rarely retain customers. The most durable startups solve concrete problems for specific customers. In closing, the hosts reflect on how this AI boom mirrors prior technological revolutions. Once again the earliest pioneers are hardcore technologists dismissively labeled as "geeks" - yet history suggests they may build the next generation of iconic companies. For entrepreneurs willing to search for valuable problems hidden in plain sight, it is an unprecedented time full of opportunity.

Should You Be Optimistic About The Future of Technology?

January 1, 2024
Episode Summary
The hosts of the podcast discuss why they are optimistic about the future of technology. They acknowledge that in their work they see many startups fail on a daily basis. However, when zooming out and looking at the big picture, they highlight all the ways technology has improved dramatically in just the past few decades - the availability of information via the internet and sites like YouTube, communications technology like smartphones that allows free calling and messaging globally, transportation innovations like ride sharing and self-driving vehicles, improvements in healthcare and standards of living across the globe, and the abundance of entertainment options available instantly online. The hosts note that it's easy to be pessimistic if you just focus on the negative news stories about technology. However, they argue that you have to have perspective and acknowledge that progress comes with tradeoffs. The pacing of innovation is also uneven across industries. Just because some problems persist doesn't mean we shouldn't be excited about solutions happening in other areas that will have meaningful impacts on people's lives. They express optimism not only because of how much better things have gotten so recently, but also because of the innovations they see coming in the near future - satellites providing internet access globally, mature self-driving vehicles that will drastically reduce accidents, continuing advances in renewable energy. The hosts are particularly excited about innovations that will allow faster transportation across the globe. Ultimately, they are optimistic because they see how much technology can continue improving their kids' lives in the coming decades. They argue if you want to create positive change in the world, it's better to have an optimistic mindset focused on solutions rather than just criticism.

AI and the Future of Law: The 10 Year "Overnight" Success Story

December 28, 2023
Episode Summary
Jake Heller is the co-founder of CaseText, a legal technology company that uses AI to help lawyers do legal work faster. CaseText was recently acquired for $650 million, demonstrating the huge opportunity in applying AI to traditional industries. Jake started off on a traditional legal career path, working at a big law firm and clerking for a federal judge. During this time, he saw how technology was making basic consumer tasks very easy, yet legal work was still extremely tedious and time-consuming. He would spend late nights manually searching for key information that could determine the outcome of billion-dollar lawsuits or criminal cases. This motivated Jake to start CaseText in 2013 to bring modern technology to the legal industry. Initially, CaseText focused on crowdsourcing and early natural language processing to build features like automatically recommending relevant case law. They signed some large law firms as early customers. However, over time Jake realized that not all law firms have the same needs or appetite for adopting new technology. After some ups and downs, in 2022 CaseText got early access to the GPT-4 language model. This allowed them to build a transformative product called Co-Council that acts as an AI legal assistant. Co-Council can take on complex legal tasks like reviewing contracts or documents and provide analysis at a level comparable to a human lawyer. This creates tremendous time savings - tasks that would take days can now be done in minutes. CaseText started rapidly adding millions in monthly revenue as law firms saw tremendous value in the product. This represented true product-market fit. Jake emphasizes that while the raw AI models are incredibly powerful, a lot of work goes into building an applied product on top that solves real customer needs. Jake believes we're just at the beginning of tapping into these large language models to compress traditional human work down to software. He sees it as a fundamental platform, like cloud computing, that startups can build on top of to create magical products across industries. Jake encourages entrepreneurs to start companies now and take advantage of these opportunities unlocked by AI.

How To NOT Get Screwed As A Software Engineer

December 21, 2023
Episode Summary
The podcast "How To NOT Get Screwed As A Software Engineer" aims to provide advice to technical people who may find themselves exploited in their roles. The hosts, Dalton and Michael, address several common situations where engineers can get taken advantage of. They first discuss equity splits at startups. A problematic but frequent scenario is when a non-technical founder retains a much larger equity share (e.g. 90%) compared to the technical co-founder (e.g. 10%). There is often no reasonable justification for such an imbalanced split, beyond the business founder having "sharper elbows" in negotiations. The hosts argue technical co-founders should have close to equal equity as they will take on equal responsibilities and effort as the company grows. Similarly, early technical hires/first engineers at startups often get less than 1% equity despite providing co-founder level work. The hosts advise these employees should still get a meaningful stake so they are properly incentivized - if the company succeeds, their equity should be "life-changing" money. The hosts discuss other signs technical talent is being exploited, like not having a seat at the decision-making table and being left out of key business meetings. Another red flag is if the technical person is working extremely long hours while counterparts in non-technical roles work more reasonable schedules. Technical staff shouldn't be treated solely as "code writing machines" without a voice in strategy. The hosts emphasize that positive situations do exist where engineers get fair deals. Signs of a good environment include the technical person feeling privileged to work at the company, getting ample opportunities for learning/career development, and having properly set expectations on effort/responsibilities required. The hosts conclude with advice if someone finds themselves potentially exploited - consider other jobs/companies where your skills may be better valued, directly ask for more equity/decision-making involvement, or take calculated career risks to improve your long-term prospects.

Silicon Valley's Cargo Culting Problem

July 13, 2023
Episode Summary
The podcast discusses the concept of "cargo culting", which refers to superficially copying something without understanding why you're copying it. This is often done in the startup world, where founders copy successful companies without thinking through whether those tactics actually make sense for their own business. Some examples discussed: - Copying Google's office culture, like open floor plans and free snacks, without realizing these perks were not the key to Google's success. - Trying to go viral like Facebook without considering that most products don't get used for hours per day like Facebook did, so different tactics are needed. - Expanding to multiple cities quickly and spending aggressively like Uber, without looking at whether unit economics actually support that expansion. The hosts argue that blind copying often fails because it ignores the deeper reasoning behind a successful company's strategy. What works for a Google or Facebook isn't necessarily right for every business. They suggest starting with the user - understand their needs, see what they currently use and pay for, and learn from companies successfully serving that user. With that lens, founders can thoughtfully adapt and integrate ideas, rather than blindly copying. Superficial startup posturing, like fundraising announcements, press, and vanity metrics, can drive cargo culting of unproven, often unsuccessful companies. But real success comes from providing genuine value to users.

How To Go From Startup Dream To Reality

June 15, 2023
Episode Summary
The podcast discusses how founders need to confront the reality of potential failure in their startups in order to avoid actually failing. The host shares a personal story of how his startup Postures experienced strong growth for two years before suddenly plateauing in 2010. However, the host refused to accept that his startup was going to fail. He looked for data that indicated things might improve while lying to himself, employees and investors that success was still achievable. The podcast explains that founders need to change their beliefs and models when confronted with evidence that contradicts their assumptions. Just like in the movie The Truman Show, founders are often blind to the reality that their understanding of the world might be completely wrong. Overcoming the fear of a startup dying allows founders to see the truth. The host points out the confusing aspect of this is that founders also need to believe in their startup dreams to make them happen. But this dreamland shouldn't be the only perspective. Founders must bridge dreamland and reality by surrounding themselves with smart people who challenge their assumptions. This allows more robust mental models to develop through experimentation and criticism. In summary, the podcast emphasizes that founders should immerse themselves in both dreamland and reality in order to create success. Having an individual dream is not enough - you need to test that dream against the reality through a process of falsification and feedback from others. This allows you to turn your dream into actual change in the real world.

Secrets You Can Learn From Your Customers

June 5, 2023
Episode Summary
The main idea of this podcast is that early stage founders can learn a tremendous amount about their customers' problems and how to solve them by spending time with and caring about their customers. The Airbnb founders helped their hosts get professional photos for their listings, even though they knew the hosts would also use those photos on competing sites. By doing this gesture of goodwill, the founders built trust and a host invited them in for coffee. During this meeting, the host shared his detailed notebook containing 10 years of insights from renting out his apartment. This exemplified how caring about customers and spending time with them can provide unique learning opportunities. Similarly, the Brex founders pivoted their startup to focus on serving other startup founders after realizing they best understood that customer segment. By getting to know founders personally and asking about their pain points, Brex learned about the challenges of obtaining corporate credit cards and tailored their product to specifically address those needs. Again, caring about their personal network yielded valuable customer insights. At Justin.tv and later Twitch, the founders had a troubled relationship with their users who were streaming unauthorized content. But when they started reaching out to individual gaming streamers, asking about their needs, and implementing simple improvements like higher video resolution, they built trust. This eventually led to conversations where the founders learned that streamers would create better content if they could make money doing so. This insight was core to the Twitch platform. Overall, these examples demonstrate that founders can accelerate learning by caring about customers, spending time with them, and having empathy to understand their problems. This hands-on approach yields insights that surveys or hired consultants cannot.

Inside The Most Powerful Startup Community In The World

April 21, 2023
Episode Summary
In 2005, Y Combinator was founded by four people with the goal of helping startup founders succeed. By bringing together talented technologists and providing them with funding and a strong community, YC aimed to give founders a huge advantage. The first YC batch included startups like Airbnb that went on to become massively successful. YC has funded hundreds of companies at a time, producing many generational startups like Stripe, Airbnb, and Coinbase repeatedly. YC is the most powerful startup community in the world. At YC, founders can learn to move at the speed required for success. For example, Airbnb's founders Brian Chesky said they worked nonstop for 3-4 months during YC, allowing them to focus and create momentum. The reason YC exists is to accelerate startups. For three months, everything is focused on helping founders succeed. The group partners, fellow founders, alumni, and speakers all provide support. This acceleration is unmatched. YC is the best place to achieve product-market fit, where a startup transitions from an idea to a validated concept. Skills like pivoting, listening to customers, and finding product-market fit are what YC excels at. Over 90 YC companies have reached billion dollar valuations. At YC, being surrounded by experienced founders enables magic to happen. Founders get dedicated group partners who have seen hundreds of startups. Partners can spot patterns and prevent mistakes. Fellow batchmates are smart founders learning alongside you. Alumni numbering 9000+ globally can provide expertise in any sector or geography. YC's private social network Bookface connects this community. YC also provides programming, recruiting services, and $500k in funding. With so much support for early teams, there's no such thing as too early to apply. YC has created more prosperity than perhaps any other organization by changing founders' lives.

Investors Said No, Now What?

January 12, 2023
Episode Summary
YC Group Partners often find themselves repeating the same advice to founders who have been rejected by investors. When a founder gets a "no" from an investor, they tend to overly trust the investor's expertise and the reasons given in the rejection email. However, investors rarely have deep insight into a startup's space. Their knowledge is surface level at best. Investors also have an incentive to appear confident in their opinions, even if they lack expertise. Founders shouldn't take investors' reasons for rejection as gospel. The stated reasons are often polite excuses, not the real reasons for rejection. The real reasons are more likely fundamental issues like lack of a technical co-founder, poor finances, building a non-software product, or simply lack of progress over time. Investors also often reject startups because the founder doesn't seem capable of building a large company long-term. When pitching investors, founders should take notes on feedback but not internalize rejections deeply. If founders hear the same rejection reason from multiple investors, they should consider it but not necessarily believe it. The only way to get an accurate signal is to pitch many investors. Rejections are usually because the founder doesn't fit the investor's pattern for success or doesn't rank highly compared to other founders in their pipeline. The best thing founders can do after being rejected is make concrete progress on their startup, not attempt to convince investors through words alone. Investors are most swayed by traction and progress. YC sees this often, as 60% of startups they fund were initially rejected. The key is that those founders made significant progress between applications. Overall, founders should stay confident when fundraising and focus on building their startup, not obsessing over individual investor rejections.

How to Get and Evaluate Startup Ideas with Jared Friedman | Startup School

December 15, 2022
Episode Summary
Title: How to Get and Evaluate Startup Ideas with Jared Friedman - The most common mistakes founders make with startup ideas are: building something that doesn't solve a real problem, getting stuck on "tar pit" ideas that seem good but are actually very hard to execute successfully, and jumping into an idea without evaluating if it would make a good business. - To evaluate if an idea is good, ask questions like: Does your team have founder-market fit? Is it a big market or rapidly growing market? How acute is the problem you're solving? Do you have competition? Do people you know personally want this? Has something changed recently to create this opportunity? Would you want to work on this idea for years? Is it a scalable business? Is it in a good "idea space"? - Ideas that seem bad but are often good: ideas that are hard to get started, ideas in a boring space, ideas with existing competitors. These are less likely to attract other founders so you face less competition. - The best way to get startup ideas is to notice them organically through your life and work. But you can also systematically generate ideas by starting with your expertise, problems you've faced, things you wish existed, changes in the world, successful companies to model, and talking to people. - The only way to truly evaluate an idea is to launch it and see if people want it. So don't overthink it - start building and testing your idea with real users.

Avoid These Tempting Startup Ideas

December 1, 2022
Episode Summary
Title: Avoid These Tempting Startup Ideas Dalton and Michael discuss "tar pit" startup ideas - ideas that attract founders but often lead to failure because founders don't pivot away from them quickly enough. Tar pits resemble freshwater ponds so animals are drawn to them, but get stuck in the tar and die. Similarly, tar pit startup ideas seem appealing but lead to failure. Most tar pit ideas are consumer ideas - products marketed to individual people rather than businesses. Founders often default to consumer ideas because those are the startups they know from the media. However, consumer startups have a very high bar for success. Iconic successes like Google and Facebook were instantly loved by users from day one, with no marketing needed. Timing is also key for consumer startups. It was easier to gain traction in the 2000s when the technology was new and exciting. Now, consumer startups face much more competition for people's attention. Some examples of current tar pit ideas are discovery apps to find new restaurants or events, gambling/sports betting apps, and generic social networks. These spaces seem big and underserved, but thousands of startups have failed trying to execute on these ideas. The root issue is the supply/demand imbalance. Many founders want to work on "hot" ideas like social networks that sound fun to build. But the market demand for an unproven solution is low when incumbents already exist. The best pivots move into spaces with less competition from other startups and real urgency from customers. In summary, know that tar pit ideas are alluring but risky. Do your research on the competitive bar and consider pivoting to an idea with better supply/demand characteristics to improve your odds of startup success.

Things That Don't Scale, The Software Edition

October 27, 2022
Episode Summary
The podcast discusses how software companies have used hacks and shortcuts, or "things that don't scale", to get their products to work when they didn't have time to build things the right way initially. The hosts discuss how Paul Buchheit, the creator of Gmail, used an existing Google Groups product to view his own email before building out features like writing emails and inviting other users. This "dirty hack" allowed him to launch and spread Gmail within Google before they had fully built out the infrastructure and features people expected from email. They also discuss how early Facebook launched each university on completely separate code, databases, and servers to avoid having to scale one giant database. Users would have to go to harvard.thefacebook.com versus stanford.thefacebook.com. It took Facebook years after launch to build one unified database for all users globally. Justin.tv, the precursor to Twitch, also used hacks to deal with scaling live video. They built the ability to turn high traffic pages into static pages to avoid crashing servers. They also pre-populated video streams across their video servers based on website traffic before officially launching the stream to viewers. Other examples are shared from iMeme, Friendster, Google and more. The hosts conclude that the best product decisions are often made quickly, when you just "turn on the water" and see what breaks, instead of over-engineering a perfect system. The imperfect hacks allow startups to build something users want so they eventually earn the privilege to later build more scalable systems.

Where Do Great Startup Ideas Come From?

September 12, 2022
Episode Summary
The podcast discusses where successful startup ideas come from, using Airbnb, Coinbase, and Stripe as examples. Three common themes emerge: First, timing was important. For each company, there were pre-existing competitors but an opportunity to make something 10x better. Second, most people thought the ideas were bad initially, either too difficult to execute or just bad ideas overall. Third, the opportunities turned out bigger than even the founders anticipated. With Airbnb, services like VRBO existed but had friction with payments. Airbnb solved this by facilitating payments. Most people thought renting a room in a stranger's home was unappealing. With Coinbase, buying bitcoin was difficult. Existing services were seen as sketchy or frequently hacked. Coinbase made it simple to buy bitcoin safely. But many saw bitcoin as a bubble and getting a bank to work with them seemed impossible. Stripe dramatically simplified accepting credit card payments online. Before Stripe it was difficult, time-consuming and expensive to set up. But many thought online payments were crowded and startups couldn't compete with large players like Paypal. In all three cases the founders ignored conventional wisdom and executed well to provide a dramatically better product in an area with pre-existing solutions. The markets proved larger than almost anyone anticipated. The overarching theme is successful founders often have to ignore criticism and persist despite a contrarian viewpoint.

Saving Your Startup During an Economic Downturn

July 21, 2022
Episode Summary
The podcast episode discusses the concept of "default alive" vs "default dead" startups. A default alive startup has a high enough growth rate that it will become profitable before running out of cash, even without raising more investor money. A default dead startup will die in a few months if it does not raise more funding. The hosts explain why many founders ignore thinking about whether their startup is default alive or default dead. Founders often assume they will be able to easily raise more funding. They feel it hurts confidence to question this assumption. Also, the metrics founders use to pitch investors focus on growth, while the metrics needed to judge sustainability focus on burn rate and profitability. The hosts emphasize that most startups are default dead. Raising funding gets harder each round as the pool of possible investors shrinks. Founders should not rely on being acquired as a backup plan if fundraising fails. Acquisitions almost never happen when a startup is low on cash and close to bankruptcy. If a startup realizes it is default dead, tough decisions are required to become default alive. This usually involves cutting costs, especially by reducing headcount. Founders also need to cut advertising spending if it has a low return on investment. Finally, startups often need to raise prices, even if it means lower growth. The hosts share examples from their personal experience. One host had to have an embarrassing meeting telling employees the startup had to rapidly get profitable or die. The employees rallied, costs were cut, and revenue increased. This experience gave them time to eventually find product-market fit. The key takeaways are that startups must survive before they can thrive, and profitability should come before rapid growth. Founders are ultimately in control, not investors, and must make tough decisions to steer away from the "mountain" of bankruptcy.

#155 - Laks Srini

December 11, 2019
Episode Summary
Episode Title: #155 - Laks Srini - Laks Srini is the co-founder and CTO of ZeroDown, a company that helps people buy houses with no down payment. - The idea for ZeroDown came from Laks' co-founder Abhijit, who despite having a good tech job could not afford a down payment on a house in the Bay Area. - They spent 18 months researching the mortgage industry and talking to other failed mortgage startups to understand the challenges. - To test the idea, they tried to help Abhijit buy a house through their model but ultimately started ZeroDown instead. - ZeroDown buys the house for the customer upfront, then the customer makes monthly payments. As they pay, they earn "purchase credits" equivalent to equity in the home. After 2 years they can buy the home from ZeroDown. - The company operates both a tech platform and a property investment fund to buy and hold the homes. The fund creates protections for the customers if anything happens to ZeroDown. - They focus on tech workers and others with healthy, stable incomes who can't afford a down payment. The process is fast - customers can move in within weeks. - They plan to expand to more cities soon starting with Seattle and Austin. Educating consumers on the model is a key challenge. - The team heavily focuses on customer research and feedback to improve the product experience across search, financing, services, etc. - Laks believes home ownership should be more flexible and liquid, and wants to enable more people to buy homes.

#150 - Startup School Week 9 Recap - Carolynn Levy on Modern Startup Financing and Jared Friedman’s Advice for Hard-tech and Biotech Founders

October 30, 2019
Episode Summary
Title: #150 - Startup School Week 9 Recap - Carolynn Levy on Modern Startup Financing and Jared Friedman’s Advice for Hard-tech and Biotech Founders Carolynn Levy's Lecture: - Early stage startup financing has changed dramatically over the past 20 years. Startups now often use convertible securities like SAFEs for their first fundraising instead of priced equity rounds. - Priced equity rounds like Series A still happen but later, after using convertible instruments first. This allows startups to focus on building the company instead of spending months on financing paperwork. - SAFEs and other convertible instruments are faster, cheaper, and more flexible than priced rounds. But founders must still track dilution carefully. Jared Friedman's Lecture: - Hard tech companies require lots of time and money to build products, with uncertainty if it's even possible. But it's easier to generate interest in ambitious hard tech ideas versus traditional startups. - Common hard tech problems are needing millions to build a product and proving market demand. Smart founders find low-cost ways to make initial progress and get customer commitments. - Hard tech companies should fundraise in small increments with concrete milestones to complete before raising the next round. This approach is better than seeking a huge round upfront.

#149 - Startup School Week 8 Recap - Adora Cheung on Prioritizing Your Time and Kevin Hale on Evaluating Startup Ideas

October 23, 2019
Episode Summary
Adora Cheung's Lecture on Prioritizing Time - Time is precious when working on a startup. Prioritize tasks that will have the biggest impact on your primary KPI (key performance indicator), which is usually revenue or active users. - Focus on "real startup progress" - activities like talking to users and building/iterating your product. Avoid "fake progress" like optimizing vanity metrics. - Keep a spreadsheet of potential tasks and rank them as high/medium/low impact and easy/medium/hard complexity. Do high-impact, easy tasks first. - Review your weekly goals and updates to ensure you're making real progress. Are you learning quickly? Avoiding low-value work? Completing tasks efficiently? - Structure your schedule thoughtfully. Block time for focused work like coding versus meetings. Avoid constant context switching. - Move fast, make decisions quickly, and learn from mistakes. Speed is important. Kevin Hale's Lecture on Evaluating Startup Ideas - A startup idea is a hypothesis for fast growth based on the problem, solution, and insight. - Communicate ideas clearly and concisely. Help investors understand, get excited about, and want to work with you. - Lead with what you're making, not why/how. Be clear and reproducible. Include the key nouns - what you're making, the problem, the customer. - Use an "X for Y" model sparingly and correctly. X should be a huge success, Y should want X, and Y should be a big market. - Concision shows deep understanding of your idea and efficiency as founders. But don't sacrifice critical details. - Help investors evaluate your idea efficiently. Be clear, concise, and compelling.

#147 - Startup School Week 6 Recap - Tim Brady on Culture and Dalton Caldwell on Pivoting

October 9, 2019
Episode Summary
Tim Brady's Lecture on Culture: - Company culture is the implicit set of behaviors that inform employees on how to act. Getting the culture right early on makes it easier to scale later. - Be proud of the problem you are solving. This gives purpose and energy to the work. - Create an inspiring long-term vision to attract the right people to your company. Don't just describe the work, talk about its purpose. - Have a conversation with your co-founder about the values and behaviors you want to cultivate. Use this as a hiring filter. - Focus the culture outwardly on customers, not just inwardly on how you treat each other. - Discuss diversity early on. Homogeneous environments are hard to change later. - Put a hiring process in place from day one and iterate on it. You want it tested before you scale up. Dalton Caldwell's Lecture on Pivoting: - Pivoting just means changing your idea, which should feel lightweight early on. Constantly iterate. - The main reason to pivot is opportunity cost - putting more time into an idea not working rather than trying something new. - Good reasons to pivot include lack of excitement, no growth, relying on external factors, and running out of ideas. - Don't pivot to avoid hard work or just because something new seems hot. See it through fully first. - To find a better idea, get excited about solving a problem and believe you can. Make your strengths align with the idea. - Launch quickly and talk to customers to get evidence for whether to pivot. Multiple quality attempts increase your odds.

#144 - Startup School Week 3 Recap - Anu Hariharan and Adora Cheung

September 18, 2019
Episode Summary
- Anu Hariharan gave a lecture on the 9 most common startup business models and key metrics investors want to see for each: 1. Enterprise - Track bookings, number of customers, and revenue. Don't confuse bookings and revenue. 2. SaaS - Track MRR, ARR, revenue churn, and CAC. Make sure you have true recurring revenue. 3. Subscription (consumer) - Track MRR, monthly growth, and unit churn. Focus on user volume metrics. 4. Transactional - Track gross transaction volume (TPV), net revenue, and user retention. Don't confuse TPV and revenue. 5. Marketplace - Track GMV, net revenue, monthly growth, and user retention. Carefully track paid CAC. 6. Ecommerce - Track monthly revenue, growth, gross margins, and CAC. Account for all costs in gross margins. 7. Advertising - Track daily and monthly active users and % logged in. Clearly define an active user. 8. Hardware - Similar to ecommerce, track revenue, growth, margins, and CAC. 9. Services - Track bookings, revenue, and number of customers. - In a Q&A, Anu and Adora discussed how investors evaluate startups. Key points: - Investors focus on team, product-market fit, and market size. Team and clarity of vision are most important early on. - Progress and learnings matter more than absolute traction. Show you can build quickly. - Remote teams are increasingly common. Execution is more important than location. - Solo founders can impress investors with their vision and ability to build a strong team. - Only raise as much money as you need to hit the next milestone. Stay focused. - For enterprise sales, show progress through pilots with early customers. - When fundraising, have a clear plan on how you will use the capital.

#142 - Startup School Week 1 Recap: Kevin Hale and Eric Migicovsky

September 4, 2019
Episode Summary
This episode recaps the first week of Y Combinator's Startup School program. It includes condensed lectures from two YC partners, Kevin Hale and Eric Migicovsky. Kevin Hale's lecture is about evaluating startup ideas. He explains that startups aim to grow quickly, so founders need to construct a hypothesis for rapid growth. This hypothesis has three parts - the problem, the solution, and the insight. Good problems are popular, growing, urgent, expensive, mandatory, and frequent. The solution should directly address the problem rather than being a "solution in search of a problem." The insight explains why the solution will succeed. Eric Migicovsky's lecture covers how to talk to users. He stresses that founders should maintain a direct connection with users throughout their company's lifespan. The goal is to extract information, not pitch ideas. Avoid hypotheticals and focus on specifics from users' lives. Listen more than talk during interviews. He suggests five questions to ask users: about the hardest parts of their problem, the last time they encountered the problem, why it was hard, what they've done to solve it, and what they don't like about existing solutions. Talking to users is critical at the idea stage, prototype stage, and during iteration towards product-market fit. In summary, evaluating startup ideas requires identifying a growing problem, matching it with an effective solution, and having an insight about the solution's advantage. User interviews should extract specifics about real experiences rather than pitches or hypotheticals, in order to drive development and growth.

Games like Pokémon GO are helping drive this installation phase. - Key technology trends like improved mobile components, more efficient processors, and faster wireless data are enabling consumer AR. 5G in particular will provide huge bandwidth improvements. - As an AR startup founder, focus on core infrastructure over applications for now. Find investors who believe in the long-term vision. - Escher Reality showed early AR demos (like AR Pong) to generate excitement. The YC brand helped them raise funding. - After being acquired by Niantic, Diana has been focused on integrating cultures and learning new skills for hypergrowth. She feels like a Niantic employee now. - Diana immigrated from Chile to the US for high school. She crunched to catch up academically and graduated college early. Her immigrant experience gives her a unique perspective. - For YC founders - use the batch to focus, get seed funding, and build relationships. Do high-leverage activities big companies wouldn't.

#139 - Jay Reno

August 14, 2019
Episode Summary
#139 - Jay Reno Jay Reno is the founder and CEO of Feather, a furniture subscription service that was part of the Y Combinator summer 2017 batch. Feather allows people to subscribe to furniture rather than buying it outright. Jay started Feather after realizing people, including himself, were constantly moving and needing new furniture that fit their new spaces. He also saw a problem with furniture waste as people buy cheap disposable furniture when moving, only to throw it out and buy new furniture at their next place. Jay first tested the idea by building a simple MVP website with a few pieces of furniture. He took orders from friends and delivered the first pieces of furniture himself. This validated that people were interested in furniture subscription versus buying. Originally called Rent Feather, Jay later tweaked the model and messaging to be more of a flexible subscription where payments go towards ownership, but people can return items anytime. This change from "rental" to "subscription" improved the business. Since going through YC and raising funding, Jay has focused on respecting the logistics and operations side of the business. He's built software and processes to make the complex furniture delivery and pickups work smoothly across Feather's markets. Jay has also had to balance his skills with new management skills as the company grew. He's focused on providing vision and support to his team leads, while also driving the business forward. Overall, Jay has loved building Feather into a real business that provides value to customers by giving them flexibility and reducing waste.

#136 - Anu Hariharan on Managing a Board

July 24, 2019
Episode Summary
Title: #136 - Anu Hariharan on Managing a Board - Managing a board can be anxiety-provoking for founders, especially when forming a board for the first time after a Series A round. - Typical board composition before Series A is just the founders. After Series A, the investor who leads the round joins the board as an outside director. As the company raises more rounds, more investors join the board. - Closer to IPO, independent board members are added for industry expertise and to form required committees. At IPO, board expands to 7-9 people. - Many founders now add a deeply trusted independent board member earlier, around Series B, to provide honest feedback as the company scales. - Ideal board meeting has structured agenda, with only brief time on status update. Main focus should be 1-2 strategic topics where the board's input is sought. - Bringing in executives for portions of the meeting can be valuable, but also good to have time for closed session with just the board. - Conflicting opinions are good - the board is there to push thinking, not just agree. CEO makes final decisions and important to clearly explain rationale. - If there is an unproductive board member, first give them constructive feedback. If no change, work with other board members or escalate within VC firm for potential replacement. - Look for trust, fundraising/M&A capabilities, network for hiring, and strategic thinking as core traits in long-term board members. Industry expertise can be added later or through advisors.

#134 - Sarah Nahm and Holly Liu

July 10, 2019
Episode Summary
Episode Title: #134 - Sarah Nahm and Holly Liu Guests: Sarah Nahm (CEO and co-founder of Lever) and Holly Liu (visiting partner at YC) Key Points: - Sarah grew up in Birmingham, Alabama and was the first person from her high school to go to college west of the Mississippi in years when she went to Stanford. She didn't see herself becoming a founder initially. - After college, Sarah got a job at Google through a serendipitous signup sheet and ended up becoming a speechwriter for Marissa Mayer. This gave her experience creating something from nothing and figuring things out on the fly. - Sarah left Google not to start a company but to gain more experience. She worked with several early stage teams including her Lever co-founders before officially founding Lever. - Lever focuses on modern recruiting software. The idea came from seeing that companies were limited by their ability to hire talent. Sarah saw knowledge work eating the world. - Lever struggled at first to find product-market fit, but kept focused on listening to customers and holding themselves accountable to users. This led them to pivot. - Lever fundraised their Series A in October 2014 after proving traction and team fit. Sarah became CEO shortly before closing the round. - Lever took an offsite to design their hiring process and think about their candidate experience before scaling hiring after the Series A. - Lever is proactive about recruiting, going beyond networks to meetups, Eventbrite, GitHub etc. The key is building relationships over time. - Lever focuses on motivation fit in early interviews to understand candidates' career goals and patterns of success/failure. - Job descriptions at Lever focus on impact in the role rather than tasks/requirements. This attracts top talent and is more inclusive. - On remote hiring, Lever benefited from staying together early on to build culture fast but is now experimenting with more distributed teams. - Lever has worked to build an inclusive culture from the start, before having a diverse team. This meant addressing issues like equitable dish duties. - Management coaching and leveraging employee resource groups are some of the structural things Lever does to foster inclusion. - Sarah's advice to startups in the YC batch is to recognize your culture is your people. Invest in recruiting and building your team.
