The Simulation Company

Pilots don’t train with real passengers. Surgeons don’t practice on real people. Actors don’t rehearse with real audiences. Yet the most consequential decisions in society get pushed straight to prod.

Products, policies, and other choices affecting millions of people are too often entrusted to intuition, experience, and luck.

What if we all had the capability to simulate the results of our decisions, to preview the effect before triggering the cause?

At Simile, we have built the first AI simulation of society, populated by agents based on real humans.

Our research pioneered the field of AI-based simulation, creating generative agents to prove that it is possible to simulate real people with high accuracy. We are now developing a foundation model that predicts human behavior in any situation, at any scale.

In response to market demand, we combined research with application. Today, leading companies use Simile to rehearse earnings calls, model litigation outcomes, and test policy changes. Soon, we envision simulating entire worlds: trillions of interacting decisions across individuals, organizations, cultures, and states.

We are backed by $100M in funding led by Index Ventures, with participation from Hanabi, A*, Bain Capital Ventures, Andrej Karpathy, Fei‑Fei Li, Adam D’Angelo, Guillermo Rauch, Scott Belsky, and others.

The future is too important to be left to chance. Join us.
