Y Combinator Application Deadline and Timeline
How YC Application Deadlines Work
Y Combinator runs four batches per year: Winter (W), Spring (X), Summer (S), and Fall (F). Each batch has an application window that opens months before the batch starts. The deadline is the last date by which you can submit to be guaranteed review for that batch. Exact dates are published on ycombinator.com/apply and in the application form.
Submitting by the deadline puts you in the queue for that batch. Late applications are still accepted and may be reviewed for the same or a later batch. For the full process, see how to apply to Y Combinator and when to apply and choosing a batch.
Typical Timeline From Application to Batch
After the deadline passes, YC reviews applications. A small percentage of applicants (often cited around 7%) are invited to a video interview. Interview invitations usually go out in the weeks following the deadline. If you are invited, you will have a short window to schedule; the interview itself is about 10 minutes. For how to prepare, see how to prepare for your Y Combinator interview.
Acceptance decisions are often communicated the same day or shortly after the interview. Accepted companies receive term sheets and join the batch, which typically runs for about three months and culminates in Demo Day. Confirm current dates on ycombinator.com; deadlines are usually in the evening PT.
Why Submit Before the Deadline
Submitting at least a few days before the deadline avoids last-minute technical issues and gives you time to fix any mistakes. It also signals that you are prepared. There is no advantage to submitting on the very last day. If you are ready, submit early and keep building; progress between submission and interview can improve your odds.
Conclusion
YC application deadlines are published for each batch on ycombinator.com. Submit by the deadline for guaranteed review; late applications may still be considered. After the deadline, expect interview invitations in the following weeks, then decisions shortly after interviews.
