The Waymo of Personalized demos
Karumi is building an AI agent that joins video calls and delivers live, interactive product demos autonomously — answering questions, navigating the product in a real browser, and booking follow-ups, 24/7 and in any language. We're a Y Combinator company with real traction (thousands of demos delivered and a growing book of paying B2B SaaS customers) and we're now growing our go-to-market team.
As a Account Executive, you'll own the full sales cycle and help us turn strong inbound demand and an outbound motion into closed revenue. You'll be the first dedicated sales hire, working directly with the founders to define our playbook from the ground up.

Why Karumi
The Team
Karumi was founded by Pablo Omeñaca and Toni López, who previously built StackAI together — Pablo as founding engineer and then COO leading customer implementations, and Toni as an early engineer building its agentic systems. They helped grow StackAI from early revenue to roughly $10M ARR.
Karumi lets SaaS companies deliver personalized product demos at scale, 24/7, in any language. Our AI agent learns from any software product, joins video calls with prospects, and navigates the product in a real browser while talking, listening, and taking actions. By delivering the “aha moment” instantly, Karumi eliminates demo waiting times and boosts conversion.
