Function Health — Mark Hyman's $365/Year Preventive-Testing Company

Dr. Mark Hyman is co-founder and Chief Medical Officer of Function Health, a direct-to-consumer preventive-health company he founded with Jonathan Swerdlin, Pranitha Patil, Seth Weisfeld, Mike Nemke, and Dan Swerdlin. According to the company, Function sells a $365-per-year membership — framed as “$1 a day” — that includes 160-plus lab tests, described by Hyman as roughly five times a standard physical, plus advanced imaging. Hyman frames the company’s mission as enabling “100 healthy years.”

2026 has been a growth year for the company. The record includes a $450M growth financing round from General Catalyst’s Customer Value Fund, announced July 30, 2026; the acquisition of the Getlabs mobile blood-draw platform (April 8, 2026); and the acquisition of SuppCo, a supplement-trust ratings platform (May 12, 2026). Function also announced a research partnership with NYU Grossman School of Medicine on earlier disease detection (Aug 12, 2026), AI integrations with Perplexity Health and Microsoft Copilot Health (March 2026), and a Robinhood Platinum Card benefit deal (July 2026). The company says it has passed 500,000 members and 100 million completed lab tests — all company-stated figures, not independently verified.

Independent coverage has been mixed. Inc. noted the direct-to-consumer lab-testing market is projected to reach $6.5B, with some experts urging caution about the category. Public Citizen’s February 2026 “MAHA, Means, Money” report flagged Hyman as a “MAHA influencer/entrepreneur” who could benefit from HHS-adjacent policies, pointing to supplement recommendations tied to Function Health results as an example of potential financial conflict — a criticism included here under the site’s for-and-against coverage policy.
