Simile raises $200M Series B at $2B valuation just 5 months after Series A

Enterprise buyers are now paying to simulate how customers will react before a single real person is surveyed.

• Simile raised $200 million in Series B funding at a $2 billion post-money valuation, led by Greenoaks with Index Ventures doubling down, just five months after its $100 million Series A.
• Simile builds AI foundation models that create simulated 'agentic twins' of consumers, letting companies test pricing, messaging or policy changes before deploying them in the real world.
• CVS Health, Deloitte, Wealthfront and Gallup already use Simile's simulations to strategize product launches, optimize customer experience and model policy trends before real-world rollout.
• CEO Joon Sung Park, a Stanford PhD known for the 2023 'Smallville' generative-agent study, co-founded Simile with Michael Bernstein, Percy Liang and Lainie Yallen.
• Since its public launch five months ago, Simile says revenue has grown 5x, headcount has passed 50, and it has run tens of millions of simulations for Fortune 100 companies.
• As generative AI makes producing content or products trivial, the bottleneck shifts upstream to knowing what will actually work for whom — a judgment problem Simile is betting enterprises will pay to outsource to simulation.
• Lead investor Greenoaks is a long-term growth fund whose portfolio includes Stripe, Figma, Nubank and Brex, signaling conviction that behavioral-simulation infrastructure is a durable enterprise AI category.
