How Function Health’s Medical Intelligence Platform Works

- Reference previous lab results and medical history
- Provide tailored health guidance
- Help users understand complex medical information
CEO Jonathan Swerdlin emphasizes: “It is not good enough to be in a world where AI exists and not be applying it to your health. You should be able to manage your biology.”
Building a Comprehensive Health Data Platform
What sets Function Health apart is its device-agnostic approach and comprehensive integration of lab testing, diagnostics, and clinical insights. The company has established an impressive operational footprint with:
- 75 current locations across the United States
- Plans to expand to nearly 200 locations by year-end
- Over 50 million lab tests completed since 2023
Security and Privacy in Healthcare Technology
In an era of increasing data privacy concerns, Function Health maintains strict security protocols. The platform meets HIPAA standards, fully encrypts user data, and never sells personal information. Swerdlin assures users: “Your data and your identity are never for sale. Every bit of your information is fully encrypted and protected.”

The development of Function Health’s medical intelligence capabilities is led by Chief Medical Scientist Dr. Dan Sodickson and co-founder Dr. Mark Hyman. Their team includes doctors, researchers, and engineers who ensure the AI model maintains medical accuracy and clinical relevance.
Competitive Landscape and Market Position
While competitors like Superpower, Neko Health, and InsideTracker operate in the health tracking space, Function Health distinguishes itself through its comprehensive approach that goes beyond typical AI coaching or wellness applications.
Future Outlook and Industry Impact
