Function Health
Function Health is an Austin-based membership platform that gives consumers direct access to 100-plus lab tests, optional full-body MRI scans, and AI-generated insights for a flat annual fee. Founded in 2021 and led by CEO Jonathan Swerdlin with physician co-founder Mark Hyman, the company sells a data-first, preventive approach to healthcare aimed at helping members catch problems early and track their biology over time. After a $298M Series B in November 2025 at a $2.5B valuation, Function has become one of the fastest-growing consumer health companies in the US.
Parsley Health
Parsley Health is a functional-medicine telehealth provider founded in 2016 by physician Dr. Robin Berzin. It pairs in-depth diagnostics and biomarker testing with longitudinal, team-based care - doctors plus health coaches - to find and treat the root causes of chronic conditions like gut, autoimmune, hormonal, metabolic and mental-health issues, rather than just managing symptoms. Originally a cash-pay membership model with clinics in New York and Los Angeles, Parsley has shifted to a virtual-first national service and in 2026 became the first functional-medicine provider to accept insurance in-network nationwide, putting its care within reach of roughly 150 million insured Americans.
