Y Combinator F25

Y Combinator's Fall 2025 batch comprised 148 companies in the quad-annual model. Each company received $125,000 for 7% equity on a post-money SAFE, plus an additional $375,000 uncapped MFN SAFE, totaling $500,000. The F25 batch continued YC's proven approach to founder funding and mentorship at scale, with consistent terms and high quality across cohorts. The cohort included founders working on AI applications (which are now table stakes), climate technology, fintech, healthcare, B2B software, consumer applications, and hard tech. The F25 batch reflected the maturity of the startup ecosystem: founders were sophisticated about market timing, fundraising strategy, and building sustainable businesses. The batch also demonstrated continued global participation in the YC program, with founders from around the world bringing diverse perspectives and solving problems across all sectors and geographies. For investors, founders, and analysts interested in late-2025 startup trends, the state of the AI and startup ecosystems, and YC's operations as a mature organization, F25 provides valuable reference material. The batch represents YC continuing to produce high-quality founder cohorts on a reliable, regular schedule.
