YC Booth
Vincent Borowiec

About

You get 90 seconds with the President & CEO of Y Combinator. No do-overs, no slides, just you, a camera, and a countdown. Garry is a live LemonSlice avatar voiced by an OpenAI-powered LiveKit agent. He's not just listening, he's watching. Your camera feed streams through a WebSocket proxy for Interhuman's live social-signal analysis, so every trace of hesitation, every spike in conviction, gets caught in the moment it happens. When the clock hits zero, your full transcript and signal history are handed back to the agent, which delivers a structured reflection on whether the pitch actually landed.
