Human behavior simulation company Simile has completed a $200 million Series B financing, with a post investment valuation of $2 billion. Simile uses real human data to train AI clones, and enterprises conduct product, marketing, and policy testing by simulating the reactions of different groups of people. Simile completed a $100 million Series A financing five months ago, during which its revenue increased fivefold. The model has been simulated millions of times for Fortune 100 companies, with clients including CVS Health, Deloitte, Gallup, and Wealthfront. Simile's goal is to simulate 8 billion people worldwide, with CEO Joon Sung Park as the first author of the Generative Agents paper.
