## Part 1: The Psychology of the Founder

1. **On Founder Demons:** "Startups end up taking on the personality of their founders. If you have unexamined demons inside of you, they will become your company's problems." — [*Source: \[Garry Tan on YouTube*](https://www.youtube.com/@garrytan?ref=antoinebuteau.com)*\]*
2. **On Earnestness:** "The number one characteristic of a successful founder isn't the flashiest resume; it's earnestness and extreme sincerity." — [*Source: \[FS Blog*](https://fs.blog/knowledge-project/garry-tan/?ref=antoinebuteau.com)*\]*
3. **On the Golden Shadow:** "The qualities you most admire in your heroes might exactly be what you need to unlock in yourself." — [*Source: \[Garry Tan on YouTube*](https://www.youtube.com/@garrytan?ref=antoinebuteau.com)*\]*
4. **On Therapy for Founders:** "If you're not aware of your internal default programming, then it will rule you. Doing the internal work is a business requirement." — [*Source: \[Garry Tan on YouTube*](https://www.youtube.com/@garrytan?ref=antoinebuteau.com)*\]*
5. **On Burnout:** "Be as dogged in your self-care as you are in your work ethic. You cannot build a decade-long company running on adrenaline alone." — [*Source: \[Garry Tan on YouTube*](https://www.youtube.com/@garrytan?ref=antoinebuteau.com)*\]*
6. **On Self-Belief:** "The biggest risk for ambitious misfits is that someone talks them out of their own potential before they even start." — [*Source: \[Y Combinator*](https://www.ycombinator.com/?ref=antoinebuteau.com)*\]*
7. **On Default States:** "When under pressure, founders revert to their deepest insecurities. Knowing what yours are is the only way to catch yourself before you break the company." — [*Source: \[Garry Tan on YouTube*](https://www.youtube.com/@garrytan?ref=antoinebuteau.com)*\]*
8. **On Imposter Syndrome:** "Everyone is guessing. The only difference between you and the people you admire is that they started executing while they were still unsure." — [*Source: \[Twitter*](https://twitter.com/garrytan?ref=antoinebuteau.com)*\]*
9. **On Motivation:** "Don't aspire to glory. Aspire to be useful. The market rewards utility, not ego." — [*Source: \[Garry Tan on YouTube*](https://www.youtube.com/@garrytan?ref=antoinebuteau.com)*\]*
10. **On Emotional Resilience:** "Startups rarely die from market wounds; they implode under fractures in the founder's psyche." — [*Source: \[Garry Tan on YouTube*](https://www.youtube.com/@garrytan?ref=antoinebuteau.com)*\]*

## Part 2: Design and Human Connection

1. **On the Startup Advantage:** "When you're starting something new, your whole advantage over the incumbents is that you're a real human being. Be small. Be human." — [*Source: \[Garry Tan on YouTube*](https://www.youtube.com/@garrytan?ref=antoinebuteau.com)*\]*
2. **On Customer Support:** "Being small means you can have extreme, fanatical customer support. Tell users, 'I'm the CEO, what do you need?' That builds unshakeable loyalty." — [*Source: \[Garry Tan on YouTube*](https://www.youtube.com/@garrytan?ref=antoinebuteau.com)*\]*
3. **On Product Design:** "Design is not merely how it looks, it is actually also how it works and how it feels to the person using it." — [*Source: \[Y Combinator Library*](https://www.ycombinator.com/library?ref=antoinebuteau.com)*\]*
4. **On the Party Framework:** "Think about starting a startup like throwing an amazing party. You greet them at the door, take their coat, and introduce them to friends. Software should feel like that." — [*Source: \[Garry Tan on YouTube*](https://www.youtube.com/@garrytan?ref=antoinebuteau.com)*\]*
5. **On User Personas:** "You need to know exactly who you are building for. At Posterous, we built for 'David the Dad' so we knew exactly what to simplify." — [*Source: \[Y Combinator Library*](https://www.ycombinator.com/library?ref=antoinebuteau.com)*\]*
6. **On the Meaning of Logos:** "A great logo mixes meaning and aesthetics. At Palantir, the logo represented both the infinite book of knowledge and a tool for seeing hidden truths." — [*Source: \[Garry Tan on YouTube*](https://www.youtube.com/@garrytan?ref=antoinebuteau.com)*\]*
7. **On Friction:** "If a user has to think about how to use your product, you've already lost them to someone who made the same action thoughtless." — [*Source: \[Twitter*](https://twitter.com/garrytan?ref=antoinebuteau.com)*\]*
8. **On Design as Culture:** "Design isn't just about the product interface; it's about putting together a culture and translating a mission into something tangible." — [*Source: \[Medium*](https://medium.com/@garrytan?ref=antoinebuteau.com)*\]*
9. **On the Infinite Book:** "The computer is the infinite book. Our job as designers is to help humans interface with this infinite data to understand the world fundamentally." — [*Source: \[Garry Tan on YouTube*](https://www.youtube.com/@garrytan?ref=antoinebuteau.com)*\]*

## Part 3: Engineering and Building Products

1. **On Building Instead of Consulting:** "Don't sell your time. Go make products. Time is finite, but if you make software, it keeps making money for you while you sleep." — [*Source: \[Garry Tan on YouTube*](https://www.youtube.com/@garrytan?ref=antoinebuteau.com)*\]*
2. **On Code as Scale:** "Writing code is the highest impact activity you can engage in. It scales infinitely at near-zero marginal cost." — [*Source: \[Twitter*](https://twitter.com/garrytan?ref=antoinebuteau.com)*\]*
3. **On the Golden Age of Building:** "We are in the first pitch of the first inning of what AI will enable. We are in a golden age of building." — [*Source: \[Podcast Notes*](https://podcastnotes.org/?ref=antoinebuteau.com)*\]*
4. **On Human Agency in AI:** "Current AI systems are incredibly smart toasters with no agency. That means the human element and human direction are more important than ever." — [*Source: \[Garry Tan on YouTube*](https://www.youtube.com/@garrytan?ref=antoinebuteau.com)*\]*
5. **On Technical Co-founders:** "If you are building a tech company, you need someone in-house who can build the technology. Outsourcing your core competency is a death sentence." — [*Source: \[Y Combinator Library*](https://www.ycombinator.com/library?ref=antoinebuteau.com)*\]*
6. **On Shipping Quickly:** "If you aren't embarrassed by the first version of your product, you launched too late. Get it out and let the market tell you what's wrong." — [*Source: \[Twitter*](https://twitter.com/garrytan?ref=antoinebuteau.com)*\]*
7. **On Solving Hard Problems:** "The best startups look like new elements on the periodic table. They require deep, physicist-like understanding from the engineers building them." — [*Source: \[Medium*](https://medium.com/@garrytan?ref=antoinebuteau.com)*\]*
8. **On Software as Magic:** "Software is the closest thing we have to magic. You type words into a screen, and it changes the physical world." — [*Source: \[Twitter*](https://twitter.com/garrytan?ref=antoinebuteau.com)*\]*
9. **On Engineers Selling:** "We take mostly technical people with big ideas and teach them how to sell. You can teach a great engineer to sell, but teaching a salesperson to engineer is much harder." — [*Source: \[Y Combinator*](https://www.ycombinator.com/?ref=antoinebuteau.com)*\]*

## Part 4: Early-Stage Survival and Pivots

1. **On the Three Startup Killers:** "Companies die for three reasons: co-founder conflict, failing to pivot when the market demands it, and losing belief." — [*Source: \[Inc. Magazine*](https://www.inc.com/?ref=antoinebuteau.com)*\]*
2. **On Starting Small:** "Founders are constantly told to think big, but it is just as important to start small. Solve one specific problem for one specific group perfectly." — [*Source: \[Initialized Capital*](https://initialized.com/?ref=antoinebuteau.com)*\]*
3. **On Losing Belief:** "Once the belief is gone from the founders, the employees, or the customers, it’s already too late. Protecting morale is protecting the company." — [*Source: \[Inc. Magazine*](https://www.inc.com/?ref=antoinebuteau.com)*\]*
4. **On the Posterous Mistake:** "When asked if we were a platform or a network, we said 'both.' Being both is a dead end. You have to pick a lane to win." — [*Source: \[Posthaven*](https://posthaven.com/?ref=antoinebuteau.com)*\]*
5. **On Pivoting:** "Persistence sometimes leads you down bad roads. This is why we actively encourage founders to pivot when the data shows the current path isn't working." — [*Source: \[Quora*](https://www.quora.com/?ref=antoinebuteau.com)*\]*
6. **On Retention:** "A 10 percent difference in user retention is the difference between a startup that's flatlining and one that's a massive success." — [*Source: \[Garry Tan on YouTube*](https://www.youtube.com/@garrytan?ref=antoinebuteau.com)*\]*
7. **On Product-Market Fit:** "You feel product-market fit. It feels like the market is pulling the product out of your hands faster than you can build it." — [*Source: \[Y Combinator Library*](https://www.ycombinator.com/library?ref=antoinebuteau.com)*\]*
8. **On Bridge Technologies:** "Sometimes you build a bridge technology, like posting by email. You have to realize when the market shifts to a new paradigm, like mobile apps, and adapt immediately." — [*Source: \[Medium*](https://medium.com/@garrytan?ref=antoinebuteau.com)*\]*
9. **On Staying Alive:** "In the early days, your only job is to not die long enough to get lucky." — [*Source: \[Twitter*](https://twitter.com/garrytan?ref=antoinebuteau.com)*\]*

## Part 5: Leadership and Decision Making

1. **On the Co-CEO Model:** "Don't let your startup die because you can't decide. Shared command between co-CEOs inevitably leads to frustration, chaos, and delay." — [*Source: \[Garry Tan on YouTube*](https://www.youtube.com/@garrytan?ref=antoinebuteau.com)*\]*
2. **On Focus:** "A startup ultimately lives or dies by its focus. The actual secret of productivity is to hyperfocus, and focus simply means saying no." — [*Source: \[Y Combinator*](https://www.ycombinator.com/?ref=antoinebuteau.com)*\]*
3. **On Founder Mode:** "Big companies lack 'founder mode' because they have too many people. Founder mode is having your hands in the dirt and touching all parts of the company." — [*Source: \[Podcast Notes*](https://podcastnotes.org/?ref=antoinebuteau.com)*\]*
4. **On Co-founder Conflict:** "Disagreements and mismatches between founders are the most common cause of early death for a startup. Choose your partners as carefully as a spouse." — [*Source: \[Inc. Magazine*](https://www.inc.com/?ref=antoinebuteau.com)*\]*
5. **On Making Fast Decisions:** "Speed is your primary weapon. A wrong decision made quickly can be corrected, but a delayed decision kills momentum entirely." — [*Source: \[Twitter*](https://twitter.com/garrytan?ref=antoinebuteau.com)*\]*
6. **On Utility:** "Calculate your impact with Elon Musk’s formula: Utility multiplied by the number of people. Your success is the area under that curve." — [*Source: \[Garry Tan on YouTube*](https://www.youtube.com/@garrytan?ref=antoinebuteau.com)*\]*
7. **On Delegation:** "You have to do things that don't scale first, but eventually, you have to hire people who are better than you at those exact things." — [*Source: \[Twitter*](https://twitter.com/garrytan?ref=antoinebuteau.com)*\]*
8. **On Authenticity in Leadership:** "People will not follow a polished corporate robot through the hardest times of a startup. They will follow an authentic human being who cares." — [*Source: \[Garry Tan on YouTube*](https://www.youtube.com/@garrytan?ref=antoinebuteau.com)*\]*
9. **On Managing Psychology:** "The hardest part of being a CEO isn't the strategy; it's managing your own psychology and the psychology of your executive team." — [*Source: \[Twitter*](https://twitter.com/garrytan?ref=antoinebuteau.com)*\]*
10. **On Clear Communication:** "If the team doesn't understand the goal, that is a failure of the CEO's communication, not the team's comprehension." — [*Source: \[Garry Tan on YouTube*](https://www.youtube.com/@garrytan?ref=antoinebuteau.com)*\]*

## Part 6: Venture Capital and the Seed Stage

1. **On the Why Now Framework:** "The most powerful startups emerge when three factors converge: new technologies, changes in human behavior, and shifts in regulation. You need to answer 'Why now?'" — [*Source: \[Unicorn Growth*](https://unicorngrowth.io/?ref=antoinebuteau.com)*\]*
2. **On Earned Secrets:** "The best startups are founded by people who have 'earned secrets' through direct, painful experience in a specific industry." — [*Source: \[Unicorn Growth*](https://unicorngrowth.io/?ref=antoinebuteau.com)*\]*
3. **On the Role of an Investor:** "Even more important than writing the check, we help founders tell the story, recruit the first engineers, and get the next round of capital." — [*Source: \[Crunchbase*](https://news.crunchbase.com/?ref=antoinebuteau.com)*\]*
4. **On the Spray and Pray Model:** "We rejected the spray and pray model at Initialized. The right trade-off is working with a smaller number of companies and spending massive time with them." — [*Source: \[Crunchbase*](https://news.crunchbase.com/?ref=antoinebuteau.com)*\]*
5. **On the Canonical Startup:** "A canonical startup mixes a wildly smart business idea with hard technology. When we see that, we convince the founders to quit their jobs immediately." — [*Source: \[Crunchbase*](https://news.crunchbase.com/?ref=antoinebuteau.com)*\]*
6. **On Evaluating Pitch Decks:** "I look for clarity above all else. If you can't explain what you do in one sentence, you haven't thought about it hard enough." — [*Source: \[Twitter*](https://twitter.com/garrytan?ref=antoinebuteau.com)*\]*
7. **On Board Seats:** "At the seed stage, you don't need a formal board. You need advisors who roll up their sleeves and act like an extension of your founding team." — [*Source: \[Initialized Capital*](https://initialized.com/?ref=antoinebuteau.com)*\]*
8. **On Valuation:** "Don't optimize for the highest valuation at the seed stage. Optimize for the partners who will actually help you survive to Series A." — [*Source: \[Twitter*](https://twitter.com/garrytan?ref=antoinebuteau.com)*\]*
9. **On Picking Winners:** "We don't pick winners. We fund relentless problem solvers and help them build environments where winning becomes the default." — [*Source: \[Initialized Capital*](https://initialized.com/?ref=antoinebuteau.com)*\]*
10. **On Market Size:** "A small market today that is growing exponentially is infinitely better than a massive, stagnant market. Invest in the derivative, not the current value." — [*Source: \[Twitter*](https://twitter.com/garrytan?ref=antoinebuteau.com)*\]*

## Part 7: The Y Combinator Philosophy

1. **On YC's Mission:** "Taking the top job at YC was a 'one in 10 billion lifetimes' opportunity to protect and grow the fountain of prosperity for innovation and venture." — [*Source: \[Forbes*](https://www.forbes.com/?ref=antoinebuteau.com)*\]*
2. **On Funding People:** "Most accelerators fund ideas. Y Combinator funds founders and transforms them." — [*Source: \[FS Blog*](https://fs.blog/knowledge-project/garry-tan/?ref=antoinebuteau.com)*\]*
3. **On YC's Engineering Roots:** "My goal in returning to YC was to bring it back to its engineering-first roots, focusing on the builders." — [*Source: \[Forbes*](https://www.forbes.com/?ref=antoinebuteau.com)*\]*
4. **On the YC Network:** "The true power of Y Combinator isn't the capital; it's the network of thousands of founders who will answer your email at 2 AM." — [*Source: \[Y Combinator*](https://www.ycombinator.com/?ref=antoinebuteau.com)*\]*
5. **On Batch Dynamics:** "Putting hundreds of ambitious people in the same batch creates a positive peer pressure that forces everyone to move faster than they thought possible." — [*Source: \[Y Combinator*](https://www.ycombinator.com/?ref=antoinebuteau.com)*\]*
6. **On Office Hours:** "The best YC office hours are the ones where a founder walks in with a complex problem, and walks out with a painfully simple, uncomfortable solution." — [*Source: \[Y Combinator Library*](https://www.ycombinator.com/library?ref=antoinebuteau.com)*\]*
7. **On Demo Day:** "Demo Day isn't the finish line; it's the starting gun for the next decade of your life." — [*Source: \[Twitter*](https://twitter.com/garrytan?ref=antoinebuteau.com)*\]*
8. **On Ambitious Misfits:** "YC is designed to be the home for ambitious misfits who don't fit into traditional corporate structures but have the drive to build the future." — [*Source: \[Garry Tan on YouTube*](https://www.youtube.com/@garrytan?ref=antoinebuteau.com)*\]*
9. **On Making Something People Want:** "It's the simplest motto in the world, yet founders spend years building things nobody wants because they refuse to talk to users." — [*Source: \[Y Combinator*](https://www.ycombinator.com/?ref=antoinebuteau.com)*\]*

## Part 8: Wealth, Career, and Scale

1. **On the Two Hundred Million Dollar Mistake:** "Once you find a rocket ship with product-market fit, don't step off the gas. Leaving early or losing focus can cost you hundreds of millions in lost equity." — [*Source: \[Garry Tan on YouTube*](https://www.youtube.com/@garrytan?ref=antoinebuteau.com)*\]*
2. **On Asymmetric Risk:** "Startups offer asymmetric risk. The downside is limited to your time and early capital, but the upside is literally uncapped." — [*Source: \[Twitter*](https://twitter.com/garrytan?ref=antoinebuteau.com)*\]*
3. **On Attention:** "Every business today is a meme. If you don't control the narrative and capture attention, your competitors will." — [*Source: \[Y Combinator*](https://www.ycombinator.com/?ref=antoinebuteau.com)*\]*
4. **On Wealth Creation:** "True wealth isn't created by a high salary. It is created by owning equity in a system that scales without your constant manual input." — [*Source: \[Garry Tan on YouTube*](https://www.youtube.com/@garrytan?ref=antoinebuteau.com)*\]*
5. **On Career Moats:** "Build a career moat by combining two disparate skills. Being top ten percent in engineering and top ten percent in design makes you entirely unique." — [*Source: \[Twitter*](https://twitter.com/garrytan?ref=antoinebuteau.com)*\]*
6. **On Choosing Where to Work:** "In your twenties, optimize entirely for learning and network, not salary. Join a company that is growing so fast it feels chaotic." — [*Source: \[Twitter*](https://twitter.com/garrytan?ref=antoinebuteau.com)*\]*
7. **On Building an Audience:** "Attention is the currency of the modern internet. If you can build an audience, you can launch any product into a warm market." — [*Source: \[Garry Tan on YouTube*](https://www.youtube.com/@garrytan?ref=antoinebuteau.com)*\]*
8. **On Optimism:** "Cynicism is cheap and easy. Unyielding, calculated optimism is the only framework that allows you to build something massive." — [*Source: \[Twitter*](https://twitter.com/garrytan?ref=antoinebuteau.com)*\]*
9. **On Playing the Long Game:** "The people who win in Silicon Valley are the ones who stay in the game for decades. Reputation compounds faster than capital." — [*Source: \[Garry Tan on YouTube*](https://www.youtube.com/@garrytan?ref=antoinebuteau.com)*\]*
