YC Announces Spring 2025 Batch: X25

Y Combinator is launching its first-ever spring batch, X25, bringing its total annual batches to four (Winter, Spring, Summer, Fall). The 'X' designation, chosen for its common use in programming, reflects YC's tech roots. This more frequent batch schedule aims to better accommodate founders' timelines and rapidly fund the surge of AI-driven startups. Applications are open until February 11th, 8 PM PT, with the program running April-June and culminating in an in-person Demo Day.
