Garry Tan
CEO & President
Y CombinatorCheck size: $500K (standard YC deal: $500K for ~7% equity via SAFE). Also invests via YC Continuity Fund at later stages.
Investment Thesis
Builder-designer-investor. 'Make something people want' is the entire thesis — inherited from Paul Graham's YC founding philosophy and now amplified by Garry's builder ethos. Believes we're in a golden age where a single person with AI can build what used to take a team of 20 — the '20x company' thesis. Previously co-founded Posterous, was a partner at YC, then founded Initialized Capital (early Coinbase, Instacart, Cruise, Flexport). Returned to lead YC in January 2023 after the Sam Altman / Geoff Ralston era. Strong emphasis on craft, design, and actually shipping. Has repositioned YC to be even more founder-friendly: increased deal size to $500K, expanded batch sizes, launched new programs. Believes YC's most important function is community — connecting founders with each other and with the alumni network. Politically active in San Francisco — ran for mayor-adjacent roles and advocates for pro-building, pro-business policies in SF.
What Excites Them
Founders who are building, not planning. Strong technical skills. Product taste and design sensibility. People who would build this even without funding. Evidence of real users, even small numbers. Founders who ship fast and iterate based on user feedback. Technical founders who also have design sense. Solo founders who are using AI to multiply their output.
What They Pass On
Founders 'playing startup.' Companies that need validation before building. People who want to raise money before building anything. Polished pitches without substance. Founders who can't demo their product. Companies where the founding team doesn't have the technical ability to build the product themselves.
How to Pitch
Apply to YC with something real. A demo beats a deck. Show that you've talked to users. Don't overthink the application — clarity and evidence of building matter more than polish. If you have taste and can ship, lead with what you've built. The YC application is deliberately short — answer clearly and honestly. Show traction if you have it, even if it's small. If you're a solo founder using AI to build, that's a strength not a weakness. Don't name-drop or use buzzwords. Be specific about what you've built and what users think of it. YC invests in people as much as ideas — show who you are and why you're the right person to build this.
Key Frameworks
The 20x Company
AI enables tiny teams (1-3 people) to build products that previously required 20+ people. This is a fundamental shift in startup economics. YC is increasingly backing solo founders and micro-teams who are leveraging AI to build at unprecedented speed.
Make Something People Want
YC's foundational philosophy. Before worrying about business models, growth strategies, or fundraising — just build something real users actually want. Everything else follows from genuine product-market fit.
Builder > Planner
Garry strongly prefers founders who build first and plan second. A working prototype beats a pitch deck every time. The act of building reveals the real problems and opportunities that no amount of planning can uncover.
Craft and Taste
Coming from a design background (Palantir, Posterous), Garry believes product taste is an underrated competitive advantage. The best founders have an instinct for what makes a product delightful. This is especially important in an AI world where everyone has access to the same models.
Community Network Effects
YC's most durable competitive advantage is its alumni network. 5000+ companies helping each other with introductions, advice, hiring, and deals. This creates a flywheel: the best founders want to join YC because of the network, which makes the network stronger.
Notable Writing
Prolific video content on startups, investing, product design, AI, and San Francisco. Videos range from startup advice to political commentary to interviews with founders. One of the most-followed VC YouTube channels.
AI enables a single person or tiny team to build what used to require 20 people. This means the unit economics of startups have fundamentally changed. YC is seeing solo founders and 2-person teams building products of remarkable quality. The implication: smaller teams, faster iteration, higher per-person output.
YC's official podcast, hosted by Garry and YC partners. Deep discussions on startup building, AI, market trends, and interviews with successful YC founders. Covers both tactical advice and big-picture thesis.
Advice that goes against conventional startup wisdom: sometimes you should be a solo founder, sometimes you should bootstrap first, taste matters more than experience, and the best founders are often the ones who break the rules.
How AI tools are changing the startup building process. You can now prototype in hours what used to take weeks. This changes who can be a founder and how fast you can validate ideas.
Prolific Twitter presence with threads on product design, startup building, SF politics, and the startup ecosystem. Known for being direct and opinionated.

Background
Designer and engineer by training. Studied engineering at Stanford. Was one of the first designers at Palantir Technologies, where he helped shape the early product design and UX. Co-founded Posterous (simple blogging platform) which was acquired by Twitter in 2012. Became a partner at Y Combinator, where he helped guide early-stage companies. Left YC to co-found Initialized Capital with Alexis Ohanian (Reddit co-founder) in 2012. Initialized became one of the most successful seed-stage funds, with early investments in Coinbase, Instacart, Cruise (acquired by GM for $1B+), and Flexport. Returned to Y Combinator as CEO and President in January 2023, replacing Geoff Ralston. Has been reshaping YC — increased the standard deal, expanded batch sizes, and refocused on the builder community. Active YouTube presence with deep startup content. Politically engaged in San Francisco — advocates for pro-building housing and business policies, has been vocal about SF's governance challenges.
