Rules

  • The on-time deadline for Winter 2027 was November 2 at 8pm PT. YC is still accepting late applications; most late applicants get a decision within a month, but it is not guaranteed.
  • On-time applicants hear back by December 11. Promising applicants interview, mostly by video in November and December, and usually get a decision the same day.
  • The Winter 2027 batch runs January to March in San Francisco, starting with a 3-day in-person kick-off, with regular meetups in San Francisco.
  • Deal: $125,000 on a post-money SAFE for 7% of the company (including any existing option pool) plus $375,000 on an uncapped MFN SAFE, committed on acceptance. YC charges no fees.
  • Open to any startup anywhere; solo founders are accepted, and companies further along are welcome if they have not raised a Series A.
  • Early Decision: apply now for a later batch (Spring, Summer or Fall) by choosing "A batch after Winter 2027" on the batch preference question.
