Jul 2026Series BGreenoaks (lead); Index Ventures; Hanabi Capital; Definition; CVS Health Ventures; Bain Capital Ventures; Factory; A*$200M$2BSimile raised $200 million in a Series B at a $2 billion post-money valuation, led by Greenoaks with participation from Index Ventures, Hanabi, Bain Capital Ventures, A*, Factory, CVS Health Ventures, and Definition. The company said the capital will accelerate development of its foundation model for human behavior and scale its simulation platform, following a $100 million Series A five months earlier that brought total disclosed funding to more than $300 million. Strategically, the round reflects investor demand for synthetic-user and human-behavior simulation tools that let enterprises test decisions before launch. Simile’s product is positioned around AI-generated “synthetic users” or “AI twins” used for software testing and decision-making simulation, with reported customers and use cases spanning enterprise research and consumer insight workflows. Simile is a simulation technology company focused on human-behavior modeling and synthetic users. The company emerged from stealth in early 2026 and is described as a Stanford spinout. Reported operating context includes rapid scaling after launch, with one source stating revenue increased fivefold since public launch and headcount above fifty, while other coverage notes the company is building a platform for simulated human decision-making and behavior testing.
Feb 2026Series AIndex Ventures (lead); Adam D’Angelo; Fei-Fei Li; Hanabi Capital; Guillermo Rauch; Andrej Karpathy; Bain Capital Ventures; Scott Belsky; A*$100M-Simile is a Stanford spinout AI startup founded by Joon Park, Michael Bernstein, Percy Liang, and Lainie Yallen, developing high-fidelity digital twins that simulate individual human decisions and behaviors using data from interviews, transaction logs, and scientific journals. The company emerged from stealth with a $100 million Series A funding round on February 12, 2026, led by Index Ventures partner Shardul Shah, with participation from Bain Capital Ventures, Hanabi Capital, A*, and individual investors including AI pioneers Fei-Fei Li, Andrej Karpathy, Adam D’Angelo, Guillermo Rauch, Scott Belsky, and others. The model, trained over seven months, enables enterprises to predict customer responses to products, UI changes, earnings call questions, and corporate announcements, positioning Simile as foundational infrastructure for AI-native decision-making. Early traction includes customers like CVS Health, which has used the platform for five months to simulate real customers for stocking and display decisions instead of focus groups, and Telstra, Australia’s largest mobile provider. Simile demonstrated predictive accuracy by forecasting eight out of ten questions on a recent earnings call. A potential partnership with Gallup could enhance its synthetic research capabilities using probability-based panels. The company addresses limitations of traditional methods like focus groups in a growing synthetic research market. Competitors in simulated human behavior include Aaru, which raised at a near-$1 billion valuation in December 2025 led by Redpoint Ventures, and stealth ventures like Prior Computers and People Make Things. Simile differentiates with its focus on individual digital twins partnered with real people data, backed by world-class researchers tied to ImageNet and Stanford. Index Ventures highlights unprecedented market pull from large enterprises across industries, comparing it to early Wiz, with funds to scale the platform amid surging demand for behavioral prediction tools.
