Karumi

Karumi is a San Francisco-based YC F25 startup building AI agents for personalized, real-time software demonstrations. Its agent joins live video calls with prospects, navigates a company’s product, adapts the demo to each user, and operates 24/7 in any language. The platform serves SaaS go-to-market teams by explaining products and creating faster buyer “aha moments” across demo, onboarding, and support.
