Y Combinator is widely considered the world's best startup accelerator. Indian startups Marketfox, Razorpay, HackerRank and International startups Dropbox, Airbnb, Stripe are among the 1500+ companies that have gone through YC.

Twice a year we invest a small amount of money ($120k) in a large number of startups (recently 105).

The startups move to Silicon Valley for 3 months, during which we work intensively with them to get the company 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.

The number 1 reason why companies don't get into YC is because they don't apply. One of the things YC is very particular about is having no prerequisites. We have taken companies that haven't been incorporated to companies with $40M revenue run rates and everything in between. YC demo day brings together the best early stage investors to the best Series A / B investors, and the YC alumni community has billion dollar companies to companies that are just starting. There really isn't a company that is too early or too late for YC.

— Michael Siebel (CEO Y Combinator) [2][3]

Application Process

  • If you want to apply, please submit your application online by 8 pm PT on October 3. Groups that submit early have a small advantage because we have more time to read their applications.
  • On October 24, by 10PM, we’ll invite the groups that seem most promising to meet us in Mountain View in early November. We’ll reimburse reasonable travel expenses.
  • We decide who to fund after each day of interviews.

Application Walkthrough

How to Apply to Y Combinator

  • Probably the biggest thing people don’t understand about the process is the importance of expressing yourself clearly. Every year we get some applications that are obviously good, some that are obviously bad, and in the middle a huge number where we just can’t tell. The idea seems kind of promising, but it’s not explained well enough for us to understand it. The founders seem like they might be good, but we don’t get a clear enough picture of them to say for sure.
  • If we get 1000 applications and have 10 days to read them, we have to read about 100 a day. That means a YC partner who reads your application will on average have already read 50 that day and have 50 more to go. Yours has to stand out. So you have to be exceptionally clear and concise. Whatever you have to say, give it to us right in the first sentence, in the simplest possible terms.
  • The best answers are the most matter of fact. It’s a mistake to use marketing-speak to make your idea sound more exciting. We’re immune to marketing-speak; to us it’s just noise.
