Y Combinator — Spring 2026 Batch · Y Combinator

The original startup accelerator. Three months in-person in San Francisco, the YC partner network and Bookface community for the life of the company, Demo Day in front of ~1,500 investors, and a network of 4,000+ alumni founders. For AI-skilled candidates specifically: YC's recent batches have been ~70%+ AI companies. The bar to get in has risen accordingly — having shipped product, talked to real users, and shown some indication of demand is increasingly the floor, not the ceiling. Honest fit signals: — You have a co-founder (or are open to YC's co-founder matching). Solo founders get in but face higher scrutiny. — You can articulate the wedge — what's the specific 1-foot-wide doorway you're going through, not the 50-foot vision you'll execute against later. — You're willing to relocate to SF for the batch. YC has experimented with remote/hybrid; the in-person batches consistently produce better outcomes by every metric YC tracks. What's not a fit: lifestyle businesses, anyone unwilling to take outside capital, or anyone who's still in the "exploring ideas" phase rather than committed to building one specific thing for the next 5–10 years.
