Simile Secures $200 Million in Series B Funding Led by Greenoaks

Simile Raises $200 Million in Series B Funding

Simile, a company based in San Francisco specializing in a simulation platform for human behavior, has successfully raised $200 million in a Series B funding round. The round, which took place on July 30, 2026, was led by Greenoaks, with participation from other notable investors including Index Ventures, A*, Factory, CVS Health Ventures, and Definition.

Company Overview and Leadership

Simile is carving out a niche in the tech world by providing a platform that utilizes artificial intelligence to simulate and predict human behavior. This ambitious technology aims to model the behavior of all 8 billion people on Earth, offering insights into decision-making processes that are fundamentally human.

The company is guided by a trio of founders: Joon Sung Park serves as the CEO, Lainie Yallen is the COO, and Michael Bernstein is also a co-founder. These leaders are at the forefront of developing Simile's groundbreaking AI models.

Strategic Use of the New Funding

The recent influx of $200 million is set to propel Simile's development of a "first-of-its-kind confidence model," which is designed to predict the accuracy of each simulation. This innovative approach aims to address the challenge of determining what to create, for whom, and how to implement it effectively.

CVS Health Ventures, one of the recent investors, has previously collaborated with Simile to tackle the issue of medication adherence. By leveraging Simile’s AI-generated "agentic twins"—digital replicas of real individuals—CVS Health sought to understand and influence patient behavior regarding prescription completion.

Investor Participation

Greenoaks led the funding round, signaling strong confidence in Simile's vision and potential. Other investors, such as Index Ventures and CVS Health Ventures, have shown interest in supporting the company's mission to revolutionize the understanding of human behavior through advanced AI technology.

Future Outlook

With this substantial capital injection, Simile is poised to advance its simulation capabilities, potentially transforming industries that rely on nuanced human decision-making. The company's ongoing efforts to refine its AI models could have wide-ranging implications, from product development to policy-making.

As Simile continues to innovate at the intersection of technology and human behavior, it stands as a significant player in the realm of AI-driven insights.
