Y Combinator is the world's leading startup accelerator, founded in 2005 by Paul Graham. YC developed a new model of early-stage funding: twice a year it invests $500,000 in select startups that move to San Francisco for a three-month intensive program. During the batch, founders work closely with dedicated General Partners—all successful startup founders themselves—meet weekly in small cohort groups, and hear from speakers including the founders of OpenAI, Airbnb, Stripe, and DoorDash. The program culminates in Demo Day, where companies present to a large audience of investors. YC's portfolio includes OpenAI ($500B), Airbnb ($100B+), Stripe ($107B), Coinbase ($86B), DoorDash ($39B), Scale AI (partial $14B+ acquisition by Meta), Dropbox ($9B IPO), Reddit ($6.4B IPO), Instacart ($10B IPO), GitLab ($11B IPO), Kalshi ($11B), Replit ($9B+), and Twitch (acquired by Amazon for nearly $1B)—a combined $1.3 trillion in portfolio value. YC continues to support founders for the life of their company through its powerful alumni network. Garry Tan, a YC S08 alum and co-founder of Initialized Capital, serves as President and CEO.
