About

Simile builds “agentic twins” — AI-simulated users that companies survey and test products against instead of running real market research 12. The startup was founded by Joon Sung Park, a Stanford PhD graduate whose dissertation project “Smallville” involved AI agents carrying on simulated human lives 1. Simile emerged from stealth five months ago with a $100M Series A and says revenue has grown fivefold since 12.
