About Y Combinator
Y Combinator created a new model for funding early stage startups. Twice a year we invest in a large number of startups and help them for three months to get their companies to the point where they can raise money on favorable terms or become profitable.
Our Story
Y Combinator was founded in 2005 by Paul Graham, Jessica Livingston, Robert Morris, and Trevor Blackwell. We started because we wanted to help smart people build things they wanted to use.
Since then, we've funded over 5,000 companies with a combined valuation of over $800 billion. Our companies have created millions of jobs and serve billions of users worldwide.
We believe the best way to predict the future is to help create it.

Our Values
Make Something People Want
This is our motto. The best startups are ones that solve real problems for real people. We help founders focus on building products users love.
Move Fast
Speed is crucial for startups. We teach founders how to build and iterate quickly, test hypotheses, and learn from users.
Be Ambitious
We encourage founders to think big and tackle important problems. The best startups often seem impossible at first.
