What You Should Know:
– Function has created a new category in preventive health—one that shifts how people think about longevity, early detection, and everyday decision-making. The company’s mission is simple but ambitious: empower people to live 100 healthy years. It began by redefining routine testing through its bi-annual, 100+ biomarker lab panel, giving individuals an expansive, longitudinal view of their changing biology.
– The acquisition of Ezra accelerated this mission further, making fast, advanced MRI and CT imaging as accessible and routine as lab work.
A New Category of Health Built on Depth, Access, and Predictive Insight
Since 2023, members have completed more than 50 million lab tests, underscoring mainstream adoption of Function’s proactive health model. Recently named to the TIME100 Most Influential Companies list, Function is helping members identify conditions such as cancer, cardiovascular disease, diabetes, thyroid dysfunction, hormonal disorders, and other silent pathologies earlier and more reliably than traditional care pathways.
Today, the company introduces the Medical Intelligence Lab (MI Lab), co-directed by Chief Medical Scientist Dan Sodickson, MD, PhD. The MI Lab unites leading clinicians, researchers, and technologists to build Medical Intelligence—a system that integrates lab results, advanced imaging, wearables, IoT data, medical records, and global research into a dynamic, deeply personalized health model. While AI is central, Function emphasizes that true insight requires the fusion of intelligent systems with expert clinical judgment.
Healthcare has long been reactive, intervening only after symptoms appear. Yet every person generates thousands of signals across a lifetime—biomarkers, patterns, micro-changes—most of which remain invisible within fragmented medical systems. Medical Intelligence aims to surface these early warning signals, continuously learn from new data, and convert complexity into meaningful, actionable guidance.
Function’s Medical Intelligence launches with three core capabilities:
• Private AI Chat that delivers context-aware explanations grounded in each member’s health data.
• Protocols that turn complex biomarker and imaging insights into simple, practical steps members can implement immediately.
• Upload Health Records, a secure vault for medical history—lab reports, imaging, visit notes—that feeds into Medical Intelligence for longitudinal interpretation.
As Mark Hyman, MD, Chief Medical Officer and Co-Founder, notes: “Function delivers depth without compromise. This is the new standard for health.”
New leadership joins to advance this vision:
• Daniel K. Sodickson, MD, PhD, Chief Medical Scientist and MI Lab Co-Director, known for inventing parallel MRI and previously serving as Chief of Innovation in Radiology at NYU Langone Health.
• Tiffany Lester, MD, Women’s Health Medical Director, translating biomarker-driven insights into strategies for personalized, equitable care.
• Neil Shah, COO, formerly COO at Slack, bringing deep experience in scaling complex platforms.
Supported by a $298 million oversubscribed Series B led by Redpoint Ventures, Function now holds a $2.5 billion valuation. The round fuels its Medical Intelligence development and global expansion. The investor roster includes A16z, Aglaé Ventures, Battery Ventures, QuantumLight, Wisdom VC, and a broad coalition of athletes, founders, and cultural leaders.
Function is designed to make comprehensive health data accessible, affordable, and understandable. Members receive over 100 lab markers—far beyond the ~19 biomarkers typically assessed during an annual physical—covering heart health, hormones, thyroid, liver and kidney function, inflammation, cancer signals, nutrients, heavy metals, and more. MRI—powered by FDA-cleared AI—takes only 22 minutes and costs $499, identifying conditions such as early-stage cancers, unruptured aneurysms, endometriosis, and stroke-related changes. CT scans extend detection to lung cancer and coronary plaque.
All data flows into one integrated interface, giving every member a personalized, continuously updated health profile. By turning complex datasets into clear next steps, Function is redefining how people monitor, understand, and act on their biology over a lifetime.
