Simile bags $200M at $2B, five months after $100M Series A, to predict what humans will do before AI gets it wrong — TFN

Simile has raised $200 million in Series B funding, reaching a $2 billion valuation just five months after closing its $100 million Series A.

Founded by Stanford PhD graduate Joon Sung Park alongside Michael Bernstein, Percy Liang and Lainie Yallen, the company develops foundation models that simulate human behaviour for businesses.

Its models predict human behaviour for CVS Health, Wealthfront, Deloitte and Gallup before they act.

Most AI startups want to help people make things faster. Simile wants to tell them whether those things will work before they exist. The Stanford spinout and Palo Alto startup has closed $200 million in Series B funding at a $2 billion valuation, five months after a $100 million Series A that launched the company into the public eye.

The round was led by Greenoaks, the San Francisco-based long-term growth fund whose portfolio includes Stripe, Figma, Nubank, and Brex, with Index Ventures doubling down on its stake and Hanabi, Bain Capital Ventures, A*, Factory, and CVS Health Ventures all returning.
