As people generate increasing volumes of health data — from electronic medical records and lab tests to wearable device metrics — making sense of that information remains a major challenge. Function Health aims to bridge that gap by consolidating health data and applying artificial intelligence to deliver personalized insights.
The company has raised $298 million in a Series B funding round led by Redpoint Ventures, valuing the company at $2.5 billion. The round also included participation from Andreessen Horowitz (a16z), Aglaé Ventures, Alumni Ventures, Battery Ventures, investment firm NFDG, and Anthony Wood. NBA players Allen Crabbe, Blake Griffin, and Taylor Griffin also participated. With this round, Function Health’s total funding now stands at $350 million.
Alongside the new capital, Function Health introduced Medical Intelligence Lab (MI Lab), an initiative focused on building a generative AI model designed to provide tailored health insights. The “medical intelligence” model is trained by physicians and integrates users’ lab results, doctor’s notes, imaging scans, and other health data to deliver personalized recommendations. Customers can access the system through an AI-powered chatbot that answers questions and offers guidance based on their unique medical history.
“It is not good enough to be in a world where AI exists and not be applying it to your health,” said CEO and co-founder Jonathan Swerdlin. “You should be able to manage your biology. The objective of Function Health is to apply the best available technology to human health.”
The company emphasizes that its platform complies with HIPAA requirements, encrypts all user data, and does not sell personal information. According to Swerdlin, user data and identity are fully protected and remain private.
Medical Intelligence Lab is being led by chief medical scientist Dr. Dan Sodickson and co-founder and chief medical officer Dr. Mark Hyman, along with a team of doctors, researchers, and engineers. Physicians remain actively involved in training and refining the AI model.
In a competitive landscape that includes companies like Superpower, Neko Health, and InsideTracker, Function Health differentiates itself through a device-agnostic strategy. The platform combines lab testing, diagnostics, and clinical interpretation rather than offering a standalone AI coach or wellness app. Function Scans, the company’s advanced MRI service focused on early disease detection, is currently available at 130 locations and is expected to expand to 200 sites by the end of 2025. Members can also access lab testing at 2,000 Quest Diagnostics locations nationwide. Since 2023, Function Health reports completing more than 50 million lab tests.
