Simile

AI simulation of human behavior

Simile is building the first simulation platform powered by AI systems that model realistic human behaviour at scale. Simulating populations rather than individuals is what makes the work useful — questions about how a policy, product or market will land depend on aggregate response, which has never been testable in advance. The company's work sits at the frontier of foundation models and human-centred AI, with founders and advisors including the lead author of Generative Agents and Stanford computer science professors Percy Liang and Michael Bernstein. It is a small, focused team of operators and researchers.
