Simile AI’s CEO Joon Sung Park describes how the company moved from the 2024 “Summer of Simulative AI” and its landmark Generative Agents paper to building digital twins that predict individual and population behavior with up to 99 % accuracy versus human focus groups.
Supported by a $2 B Series B led by GreenOaks and Index Ventures—and notable backers such as Fei‑Fei Li and Andrej Karpathy—Simile runs millions of simulations for Fortune 100 clients (e.g., CVS) to enable “what‑if” decision making before real-world execution.
Their methodology combines long‑form interviews, observational and transactional data, randomized controlled trials, and causal post‑training to model both individual-level and population-level human behavior in a scalable simulation framework.
