Simile

Enterprise AI platform simulating human behavior

Overview

Simile builds AI models that simulate human behavior to forecast how individuals and groups will respond to different scenarios, using generative agents grounded in interviews and behavioral data. Its foundation-model approach powers these agents to mimic real decision-making for tasks like testing product launches, policy changes, or corporate announcements. The platform targets enterprises seeking decision intelligence, enabling rehearsals of earnings calls, litigation outcomes, and market strategies. By grounding agents in real data and behavioral science, Simile differentiates from general AI tools and focuses on helping organizations test decisions to reduce uncertainty before acting.

Simile raises more than $200 million at a $2 billion post-money valuation.

Simile raises more than $200 million at a $2 billion post-money valuation. Key points * Greenoaks led the Series B, with Index Ventures, Hanabi, Bain Capital Ventures, A*, Factory, CVS Health Ventures and new investor Definition participating.[[1]] * The $2 billion figure is a post-money valuation; Simile did not disclose its pre-money valuation, share price or whether the round included secondary sales.[[1]] * Simile says revenue has increased fivefold since its February launch, but it provided no revenue figure, customer count or contract values.[[1]] Simile has raised more than $200 million in a Series B led by Greenoaks, giving the artificial-intelligence startup a $2 billion post-money valuation just five months after its public launch. Returning investors Index Ventures, Hanabi, Bain Capital Ventures, A*, Factory and CVS Health Ventures participated, while Definition joined as a new investor.[[1]] The Palo Alto company builds AI models intended to simulate how people and groups respond to products, marketing, pricing and other decisions. Simile says customers include CVS Health, Wealthfront, Deloitte and Gallup, and that Fortune 100 enterprises have run tens of millions of simulations through its technology.[[1]] Those product and usage figures were reported by the company and have not been independently audited. Rapid growth, limited financial disclosure. Simile said revenue has grown fivefold since it launched in February and that its workforce now exceeds 50 people. It did not provide starting or current revenue, annual recurring revenue, customer totals, pricing or retention figures, making the valuation difficult to assess against conventional software metrics.[[1]] The company also did not explain whether the $2 billion valuation resulted solely from the price paid for newly issued shares or whether the financing contained secondary transactions. The company says its models begin with data from real people and are checked against human responses. Its website claims more than 7,000 evaluations across demographic groups and enterprise use cases, along with a confidence model designed to estimate the accuracy of each simulation.[[2]] Simile has not released enough underlying commercial validation data for outsiders to test those claims broadly. Simile said the proceeds would accelerate its work and support hiring researchers, engineers, designers and operators, without providing a spending breakdown.[[1]] Index Ventures led its $100 million Series A announced on February 12, alongside Bain Capital Ventures, A* and Hanabi Capital and several individual AI investors.[[3]] TechCrunch first reported the new financing as a $200 million Series B.[[4]] Discover more Computer Science Market intelligence reports AI market analysis Discover more AI infrastructure solutions Dictionaries & Encyclopedias Web Apps & Online Tools At the intersection of AI, tech, and markets.

Daily research News online. The global MR industry's daily paper since 2000. Follow DRNO on... Prediction tech company Simile launches with $100m. February 13 2026 AI firm Simile has secured $100m in funding, to develop its prediction technology, whose applications range from forecasting consumer behavior to suggesting likely questions from analysts during company earnings calls. Simile says it is building 'a foundation model that predicts human behavior in any situation, and a product that deploys it at scale.' According to Bloomberg News, the company emerged from stealth this week after training its model on a combination of consumer interviews, transaction data and behavioral experiment findings from scientific journals. For the first of these, it taps the probability-based, nationally representative panel of partner firm Gallup. The firm was founded by Stanford researchers Joon Park (CEO, pictured), Percy Liang and Michael Bernstein, and is backed by researcher Fei-Fei Li, co-director of Stanford's Human-Centered A.I. Institute; and OpenAI co-founder Andrej Karpathy. The $100m round was led by Index Ventures, with participation from Hanabi, A* and Bain Capital Ventures. Web site: www.simile.ai.
