An open application, and it is the fund's real front door rather than a side channel. Applications run on a batch cycle: the Fall 2026 batch is October to December in San Francisco, late applications are still accepted after the regular deadline, and YC says only that if the application is promising they will invite you to interview. The program includes a three-day in-person kick-off in San Francisco.

Worth knowing. There is no referral requirement and no restriction on who may apply, which makes this one of the few genuinely open doors among the largest investors. The trade is that acceptance means joining a batch in person in San Francisco.
