# Simile Raises $200M Series B at $2B Valuation

> Simile, a Stanford spinout building foundation models that simulate human behavior, has raised a 200 million dollar Series B at a 2 billion dollar valuation. Greenoaks led the round, with Index, Bain Capital Ventures, A*, Factory, Definition, Hanabi, and CVS Health also taking part. It comes just five months after a 100 million dollar Series A, giving the company more than 300 million dollars raised in about six months. The pace is the story. Simile's backers describe one of the steepest early funding trajectories in enterprise AI, a bet that models which can convincingly stand in for human responses will be valuable across healthcare, financial services, and media. Instead of predicting text, the idea is to simulate how people might react, decide, or behave. The new capital is earmarked for core model training, the simulation compute that underpins it, and commercial teams to sell into regulated industries. The presence of a partner like CVS Health on the cap table hints at where Simile expects its synthetic-behavior models to land first.
