Function Health is a healthcare technology company focused on empowering individuals to achieve optimal health and longevity through comprehensive health awareness. It is not a laboratory or medical provider; instead, it partners with independent, medically renowned labs such as Quest Diagnostics and Grail for all laboratory and medical services, ensuring data accuracy and privacy.

The company’s core offering is an annual membership that provides over 100 lab tests at the start of each year and more than 60 follow-up tests throughout the year for $499, allowing members to monitor and manage their health proactively without insurance requirements. Function Health emphasizes removing complexity from healthcare and placing advanced health technologies directly in users’ hands.

Function Health was founded with the mission to empower people to live 100 healthy years by promoting health awareness, which they consider the foundation of a fulfilling life. Their approach combines routine whole-body lab testing with access to top medical experts, aiming to help individuals avoid disease and feel their best throughout life.

The company operates with an asset-light, technology-driven model, outsourcing lab work and leveraging telehealth doctors for medical oversight. This approach allows Function to maintain high gross margins and scale efficiently while meeting regulatory needs. Their strong growth and high subscription volume provide negotiating leverage with lab partners, enabling competitive pricing and improved unit economics.

Function Health benefits from strategic partnerships with organizations like Equinox, Thrive Global, and the National Basketball Players Association, expanding their customer acquisition channels beyond direct consumers. Co-founder Dr. Mark Hyman’s significant social media presence also supports customer outreach. As of 2025, Function Health has rapidly scaled its user base and revenue, marking its position in preventive healthcare technology.
