Y Combinator

Silicon Valley startup accelerator founded in 2005 by Paul Graham, Jessica Livingston, Robert Morris, and Trevor Blackwell. YC invented the modern batch-based accelerator model and has funded Airbnb, Stripe, DoorDash, Coinbase, Dropbox, and thousands of others. Beyond capital, its real product is the network and the operating playbook — "make something people want," weekly metrics, Demo Day — that has shaped a generation of founders.
