Y Combinator’s Startup School 2026 brought more than 6,000 founders, engineers and researchers to San Francisco’s Chase Center, making it more than three times larger than last year’s edition, according to the company.
The event featured OpenAI CEO Sam Altman, Nvidia CEO Jensen Huang, Meta’s Alexander Wang, Anthropic’s Boris Cherny and Google’s Jeff Dean, alongside founders and leaders from the Y Combinator network. Sessions covered AI infrastructure, language models, product development and commercial applications.
Beyond keynote talks, Y Combinator organised around 100 parallel sessions, research discussions, product demonstrations and networking opportunities involving founders, investors and industry experts.
AI was also built into the event itself. Attendees could use an Office Hours Simulator, which generated feedback on startup ideas through AI versions of Y Combinator partners. The event also included technology-enabled systems for following simultaneous presentations.
Anthropic offered attendees six months of free access to its Claude Max plan, while Meta provided $1,000 in credits for its services. Y Combinator also highlighted support programmes offering accepted founders more than $25,000 in cloud and AI credits through partners including OpenAI, Anthropic, AWS, Azure and xAI.
The event’s scale sparked debate among participants who felt it resembled a large public gathering rather than Y Combinator’s traditionally selective community. The accelerator defended the expansion, saying it reflects growing demand from developers and founders building AI companies.
