Simile AI, Inc.

Simile AI, Inc. is a US-based company specializing in advanced AI-driven simulation technologies that model human behavior, enabling businesses to gain insights and make informed decisions based on real-world data. Founded in 2025 by co-founders Joon Park, Michael Bernstein, Percy Liang & Lainie Yallen and headquartered in Palo Alto, US, Simile AI, Inc. focuses on developing simulation platforms that leverage AI to understand customer and employee behaviors.

In February 2026, Simile AI, Inc. raised USD 100 million in venture funding led by investor Index Ventures, with participation from other new investors Hanabi Capital, A* Capital, and Bain Capital. Simile offers an advanced simulation platform that leverages artificial intelligence to model human behavior in response to various changes. The core functionality focuses on generating simulations that reveal insights into customer and employee behaviors, allowing organizations to understand their audiences more effectively and take timely action.

This platform is particularly valuable for businesses seeking to engage hard-to-reach demographics, gather critical feedback before product launches, and validate design choices through empirical data. Simile's technology has applications across a variety of sectors, including market research, product development, and organizational strategy. The platform's reach extends to clients in North America and Europe, catering to both large enterprises and smaller organizations that aim to make data-driven decisions based on real-world behavior. Simile generates revenue primarily through a subscription-based model, offering access to its simulation platform for businesses seeking to enhance their decision-making processes.

Clients may engage in partnerships that provide tiered service levels, allowing them to customize their access based on specific needs, such as the scale of data analysis and the depth of insights required. The transactions typically involve annual or multi-year contracts, ensuring a steady revenue stream as organizations invest in long-term strategies for customer understanding and behavior modeling. The offerings include flagship services that integrate seamlessly with client operations, facilitating the transition from analysis to actionable insights without significant delays. These structured engagements enable clients to unlock valuable data while ensuring transparency and replicability in their decision-making processes.

The company will use the February 2026 funding to build and scale its AI model that creates digital twins of individuals to simulate how people respond to product changes, user interface updates, and corporate events such as earnings calls.
