Simile

Simile is a simulation platform for human behavior. Its AI-driven simulations show how and why customers, employees, or populations respond to change, so enterprise teams can find their audience, reach niche populations, de-risk decisions, segment sentiment at scale, and test concepts before a real-world launch. Simile is building a foundation model that predicts human behavior and a product that deploys it at scale. It raised a $100M Series A led by Index Ventures and is backed by Bain Capital Ventures; named customers include CVS Health, Wealthfront, Suntory, Garnett Station Partners, and Banco Itau.

Simile is profiled on the APIs.io network. Tagged areas include Company, Ai Apps, Simulation, Human Behavior, and Consumer Insights.

Simile’s developer surface includes engineering blog and 7 more developer resources.
