Karumi is backed by Y Combinator.

Fall 2025 batch. We’re building the agentic demo platform.

Karumi learns your product end to end, then demos it live on a video call to anyone who wants to see it. 24/7, in any language.

We bridge the gap between your landing page and your sales team, reaching every visitor at the peak of their interest. The Waymo of personalized demos :)

Built with ❤️ in San Francisco & New York.
