Y Combinator

We work intensively with the companies for three months, to get them into the best possible shape and refine their pitch to investors Each cycle culminates in Demo Day, when the startups present their companies to a carefully selected, invite-only audience

But YC doesn’t end on Demo Day We and the YC alumni network continue to help founders for the life of their company, and beyond

Y Combinator is a community of over 9,000 founders.

Our companies have a combined valuation nearing $1T.
