Y Combinator P25

Y Combinator's Spring 2025 batch is currently ongoing with 144 companies, representing the newest cohort in the quad-annual schedule. Each company receives $125,000 for 7% equity on a post-money SAFE, plus an additional $375,000 uncapped MFN SAFE, totaling $500,000. The P25 batch marks the introduction of the spring slot in YC's new four-cohorts-per-year model, allowing the organization to distribute founder cohorts throughout the year and provide more consistent access to the YC program. The batch includes founders working across all sectors and geographies: AI applications remain central to product development, climate technology is a significant focus area, fintech continues strong, and traditional B2B software dominates by volume. The P25 cohort demonstrates YC's commitment to founder accessibility and the scaling of its mentorship and capital distribution infrastructure. The batch is notable for being active and ongoing during the time of this research, allowing for observation of contemporary founder concerns, market dynamics, and the current state of startup funding. For current and prospective founders, investors interested in real-time startup trends, and anyone studying contemporary startup ecosystems, P25 represents the frontier of YC's work. The batch exemplifies modern startup acceleration and founder support at scale.
