## Working on now

- Karumi is focused on agentic, live product demos: an AI agent operates the customer’s real software, answers questions, and adapts the demo in real time rather than showing recordings or screenshots.
- Primary use cases are B2B SaaS marketing and sales, with expansion into onboarding, support, and internal enablement.
- The product is positioned for always-on, multilingual, personalized demos and automated lead qualification, with the agent learning product changes continuously.
- Recent company content targets the 2026 interactive-demo and AI-sales-agent markets; Karumi describes its category as agentic demos.
- Named customer examples include Workday and Brevo; the company says it serves SaaS companies, but no broader customer roster was verified.

## Summary

Karumi is an AI agent that delivers live, interactive, and personalized product demos in a real browser, serving as a 24/7 autonomous sales and onboarding representative. It sells these agentic demo services to software companies looking to improve conversion rates and streamline their GTM teams. Founded in 2025 by Pablo Omenaca and Toni Lopez, the company is a Y Combinator (Fall 2025) participant. While investors are not explicitly disclosed beyond its YC affiliation and a mention of angel investor Luis Martin, its customers include firms like Workday, Brevo, and StackAI. Karumi competes against interactive demo platforms like Storylane, Navattic, and Walnut, though it distinguishes itself by running the actual live product rather than pre-recorded tours. Its latest developments include the release of Karumi Copilot, which assists sales representatives during live calls, and a partnership with Workday that provides early access to self-serve demo features.
