Overview
Function Health is a membership-based preventive health platform that sells consumers direct access to extensive lab testing — more than 160 blood and urine biomarkers plus optional imaging — bundled with physician-reviewed reports and an online dashboard for tracking results over time. Members typically test at Quest Diagnostics locations nationwide or via at-home draws, for an annual membership fee of $365.
Co-founded in 2021 by Jonathan Swerdlin (CEO), Dr. Mark Hyman (Chief Medical Officer), Pranitha Patil (Chief Business Officer), Seth Weisfeld (Chief Design Officer), and Dan Swerdlin (General Counsel), the company is headquartered in Austin, Texas, and operates with a largely remote team. Function's stated mission is to 'empower you to live 100 healthy years' by giving members earlier visibility into biomarkers tied to chronic disease risk.
Function has expanded through acquisitions and partnerships, including its 2025 purchase of full-body MRI provider Ezra, a 2026 acquisition of at-home testing company Getlabs, and a 2026 acquisition of supplement-rating platform SuppCo. It has also built AI integrations, launching its own 'Medical Intelligence Lab' assistant and connectors that let members bring their lab data into ChatGPT, Claude, and Perplexity.
Private securities are speculative, illiquid, and involve risk of complete loss of principal. You should be prepared to hold private securities for an extended period; there is no assurance of a secondary market, an IPO, or other liquidity event. You are fully responsible for conducting your own due diligence. Pricing is indicative — nothing here is an offer of securities.
