# Simile raises $200M Series B at $2B valuation for synthetic user simulation

> Simile, a Stanford spinout, has raised a $200 million Series B at a $2 billion post-money valuation, arriving just five months after its $100 million Series A. That puts more than $300 million into the company inside six months, a pace that reflects how hot the space around simulated users has become. The core idea is to build AI agents that simulate human behavior, letting companies test decisions against synthetic populations before committing to them in the real world. Instead of running a slow, costly experiment, a business can model how people might react and iterate quickly. Simile points to uses across healthcare, financial services, and media prediction, all fields where anticipating human response carries real stakes. The obvious caution is fidelity, simulations are only as useful as they are accurate, and modeling people well is hard. Still, the funding shows investors believe synthetic behavioral testing is becoming a serious tool.
