Customer Success

About Karumi Karumi is a Y Combinator–backed (F25) company building the first agentic product-demo platform. Our AI agent joins live video calls, runs personalized product demos, reasons through prospect questions, clicks around the product in real time, qualifies leads, and routes them into the CRM — 24/7, in any language. We're a small, fast-moving team replacing a slow, manual part of the sales motion with autonomous agents. We hire ahead of need and screen carefully. Expect a sharp bar, a fast process, and real ownership from day one.
