Similar Raises $200M Series B at $2B Valuation to Simulate All Eight Billion People—and the Simulations of Those Simulations

  • Agent Simulation
  • Behavior Models
  • Market Research

Foundation models for human behavior plus confidence scores and agentic simulation rails so enterprises can stress-test products, policies, and agent fleets against synthetic populations before they touch reality.

“The hard question is no longer whether you can build something. It is what happens when eight billion simulated buyers meet your agent mesh—and then you simulate that.”

— Founder

“Behavior simulation at population scale is infrastructure for an agentic economy—Similar is building the rails under the multiverse.”

— Neil Mehta · Greenoaks
