Function Health, often stylized as simply Function, is an American health technology company and platform headquartered in Austin, Texas. The company was co-founded by Mark Hyman, Pranitha Patil, Mike Nemke, Seth Weisfeld, Jonathan Swerdlin and Daniel Swerdlin.[2][3]

The company offers a membership-based health platform with direct-to-consumer clinical labratory testing, diagnostics including full-body MRI and CT scans, clinical analysis and insights related to supplements and foods to consider.[1][4] Function Health offers five times more lab testing than is usually conducted during an annual physical exammination with a doctor, as reported by Allure and The Daily Beast.[5][6]

History

[edit]

Function Health was founded in 2021 by Mark Hyman, Pranitha Patil, Mike Nemke, Seth Weisfeld, Jonathan Swerdlin and Daniel Swerdlin.[7]

In 2023, Function Health completed more than three million lab tests.[8] As of 2024, the company had at least 100,000 members and a waitlist of 200,000.[9][10][11] That same year, Hyman stated there were over a million data points on Function Health’s first group of 10,000 people.[12]

In May 2025, Function Health acquired Ezra and planned to add its MRI scanning technology to the its platform.[4][13]

In 2025, Function Health was one of the offerings included in the Academy Awards nominees gift bag.[14] That same year, the company launched a brand campaign for Mother's Day, called "Long Live Moms."[15]

In June 2025, Function Health was named to Time's most influential companies of 2025 list.[16]

Technology

[edit]

Through its diagnostic platform, the company offers access to lab tests in areas including organ health, hormone, nutrient, metabolic and cancer signal tests. Members can schedule required lab work and tests through the platform with lab partners such as Quest Diagnostics.[17] It provides its members with lab test results with analysis and clinical summary from its doctors.[10] The results are designed to be shared with a patient's other doctors to further address the medical findings reported by the lab tests.[8]

The company's methodology is based on use of biological datapoints and phenotypic age (which is an assessment of biomarkers including albumin, creatine, glucose and mean corpuscular volume) and is based on the philosophy of personalized medicine.[18][10]

Fundraising

[edit]

Since its founding, the company conducted three seed rounds. In March 2022, the company raised $3 million, with additional rounds in December 2023, and April 2024, although the amount raised during these rounds was unreported.[19]

In June 2024, the company was valued at $191 million following its series A fundraising round of $53 million from Andreessen Horowitz, Wisdom.vc, Draft Ventures, K5 and G9 Ventures, among others.[20][19]

Function Health has received investment from institutions like 53 Stations and Embiid Ventures, as well as individual businesspeople, investors and doctors, including Ari Emanuel, Casey Means, Harvey Spevak, Harpeet Singh Rai and Jeff Dean.[2] The company also has received investment from actors and influencers like Matt Damon, Kevin Hart, Zac Efron, Pedro Pascal and Jay Shetty, and sports figures including Blake Griffin, Colin Kaepernick and Jimmy Rollins.[10][18]

Partnerships

[edit]

In May 2024, the company partnered with health club Equinox Group to offer a personalized nutrition, sleep and fitness coaching program, which included lab testing from Function Health.[9][21] The program was developed to help members measure physical and mental performance in relation to their fitness goals.[22][23] In October 2024, the company partnered with Thrive Global, a health technology company founded by Arianna Huffington. The partnership offered a health coaching program to employees.[24]

In December 2024, the company announced its partnership with biotechnology company Grail to provide members with a multi-cancer early detection (MCED) test, or liquid biopsy, that screens for 50 different types of cancers, including the Galleri test, which is a blood-based MCED test developed by GRAIL. The test reviews DNA patterns of different types of cancers before they become symptomatic.[9]

In February 2025, the company announced a partnership with the National Basketball Players Association.[25] The partnership provided NBPA members with access to its lab tests, which Forbes reported is "significantly more" than players receive in their standard medical panels through their teams.[26][27] In April 2025, the company partnered with Thatch, an employer health benefit platform, to offer employees access to preventive diagnostic testing.[28]
