Apply to Y Combinator

Winter 2019 Batch

Y Combinator is accepting applications from startups for the Winter 2019 funding cycle. It will take place in Mountain View, CA from January--March 2019.

  1. If you want to apply, please submit your application online by 8 pm PT on October 2. Startups that submit early have a small advantage because we have more time to read their applications. And you can submit after the deadline - though keep in mind that the later you apply, the harder it is to get in.

  2. On October 23, by 10PM, we’ll invite the startups that seem most promising to meet us in Mountain View either in late October, November, or early December. We’ll reimburse reasonable travel expenses.

  3. We decide what startups to fund after each day of interviews.

  4. If we invest in your startup, your company's founding team is expected to move to the Bay Area for January--March 2019. You can of course relocate the company afterward if you want, but it's a good place for a startup to be.

  5. Y Combinator doesn't supply office space. We have space your company can use if you need to, but we expect your startup to work out of wherever you find to live. It is no coincidence that so many successful startups have started this way; it's the ideal setup for the initial phase.

  6. During the 3 month cycle we'll have dinners every Tuesday for all the founders. At each dinner we'll invite an expert in some aspect of startups to speak.

  7. We have regular office hours year round for startups who want to talk about what they're building, or get advice on dealing with investors. We also have occasional events at YC.

  8. During and after the 3 months we introduce startups individually to people who could help them. The founders of other YC-funded companies tend to be especially helpful. Today the YC alumni network is probably the most powerful network in the startup world.

  9. About 11 weeks in, we organize an event called Demo Day at which the startups present to a carefully selected, invite-only audience.

  10. YC doesn't really end after 3 months; only the dinners do. We continue to give advice and make introductions as long as our startups need—-and so does the informal network of YC-funded companies.

Who We Fund

How do we choose which startups to fund?

We'll fund companies from anywhere in the world. We fund companies doing everything from building mobile apps to diagnosing cancer.

We'll happily fund companies that just started and have nothing more than an idea. And we've funded companies that had over $20M in annual revenue and over 50 employees.

International founders, please note: if your company is already incorporated as a non-United States company, to participate in YC you will need to convert your foreign company into a United States corporation (usually with a foreign subsidiary). While lawyers will drive this process, it will require a significant effort on your part.

You must have at least 10% equity in the startup to be considered a founder by Y Combinator. Only founders can come to interviews if invited or attend batch events if accepted.
