Company Overview
About Function Health
Function Health is a consumer preventive diagnostics company offering 160+ laboratory tests plus a $499 full-body MRI scan, all direct-to-consumer with AI-powered health intelligence layered on top. The company raised $298 million in Series B financing in November 2025 at a $2.5 billion valuation — the largest private fundraise in the longevity and preventive health space in history. The Medical Intelligence generative AI model, launched alongside the round, personalizes health guidance based on longitudinal biomarker data accumulated across repeat testing cycles.
Business Model & Competitive Advantage
Function Health acquired Ezra to integrate full-body MRI into its core offering, combining functional blood biomarkers (organ health, hormones, metabolic markers, cancer screening panels) with anatomical imaging into a comprehensive diagnostic picture unavailable from any single provider. The combined offering positions Function as the consumer-facing layer of the "longevity movement" — people who want data-driven visibility into their health trajectory before disease manifests.
Competitive Landscape 2025–2026
The preventive diagnostics market is large and growing rapidly, driven by a generational shift toward proactive rather than reactive healthcare. Function Health's subscription model creates recurring revenue from an affluent, health-engaged demographic willing to pay out of pocket for comprehensive monitoring. As longevity medicine moves from boutique clinics to mass-market consumer products, Function Health is positioned as the data infrastructure layer of that transition.
