YC’s Summer 2025 Demo Day (160+ startups) tilted toward AI agents and the tooling to build them. Investors flagged nine standouts: Autumn (Stripe for AI billing), Dedalus Labs (Vercel for agents), Design Arena (crowdsourced design rankings), Getasap Asia (fast retail distributor), Keystone (AI bug-fixer), RealRoots (AI friend matchmaking), Solva (automated insurance claims), Perseus Defense (cheap counter-drone missiles) and Pingo AI (AI language tutor). Several already show strong revenue or contract interest, highlighting investor appetite for AI infrastructure and monetization plays.
