Function Health

Function Health operates as a direct-to-consumer health technology platform focused on preventative care and longevity. Founded in 2022 by Jonathan Swerdlin, Pranitha Patil, and Dr. Mark Hyman, the company provides its members with comprehensive lab testing and actionable insights to manage their health proactively. The founding team's inspiration stems from personal health challenges and a collective vision to shift healthcare from a reactive to a proactive model. Dr. Hyman, a prominent figure in functional medicine and a 15-time New York Times best-selling author, serves as the Chief Medical Officer, guiding the company's scientific and medical direction. Co-founder and CEO Jonathan Swerdlin brings entrepreneurial experience from the venture capital sector, his interest in biomarker optimization fueled by his own journey with a neurological condition. Pranitha Patil, Co-founder and COO, was motivated by her personal health struggles to engineer a more accessible and empowering healthcare experience.

The company's business model is centered on an annual subscription of $499. This membership provides individuals with two comprehensive lab panels per year, conducted through a partnership with Quest Diagnostics, which has over 2,000 locations across the U.S. The initial panel analyzes over 100 biomarkers—covering areas like heart health, hormones, thyroid function, metabolic health, nutrient levels, and cancer signals—which is significantly more extensive than a typical physical. A follow-up test of over 60 markers is conducted 3-6 months later to track changes. Function Health operates on an asset-light model, not owning the labs but providing the technology and customer experience layer, which allows it to maintain transparent pricing without involving insurance, though services may be eligible for FSA/HSA reimbursement.

Subscribers receive their results through a secure digital dashboard, which includes a written summary and insights from clinicians based on the data. While the platform does not offer direct consultations or treatment, it alerts members to any urgent results. The service is designed to empower users to own their health data, track it over time, and share it with their own healthcare providers. In addition to the core lab tests, members can purchase specialized tests, such as for Lyme disease or STDs, and have access to advanced diagnostics like the Galleri multi-cancer early detection test through a partnership with GRAIL. The company has also expanded into imaging by acquiring Ezra, offering full-body MRI scans. Since its launch in 2023, Function Health has seen rapid growth, securing $53 million in a Series A funding round in June 2024, led by Andreessen Horowitz and backed by numerous angel investors.
