AGENTIC AI FOR PREVENTIVE HEALTH AND LONGEVITY - THAT IS XSPAN Most health apps tell you how you are doing today. XSpan builds a model of who you are and tells you what is coming before it arrives. YOUR DIGITAL TWIN XSpan creates a living Digital Twin of your health - a continuously updated, AI-powered biological model built from your biomarkers, wearable data, lab results, sleep patterns, activity, and clinical history. Unlike static health records or periodic checkups, your Digital Twin evolves in real time. It reflects not just your current health status, but your trajectory - where your biology is heading over the next 6 to 12 months. Your Digital Twin is what makes prediction possible. When the AI detects that your metabolic markers, cardiovascular signals, and recovery patterns are converging toward a risk event, it intervenes before your body reaches a clinical threshold. YOUR HEALTH PASSPORT XSpan generates your personal Health Passport - a comprehensive, longitudinal health profile that travels with you across every provider, specialist, and health system you interact with. Your Health Passport captures the full picture of your health: biomarker history, risk scores, intervention outcomes, medication history, and lifestyle data - organized and structured for clinical use. When you see a new provider, face a health decision, or need to share your history quickly, your Health Passport delivers it in seconds. No more repeating your story. No more fragmented records. One complete, intelligent health story. CLINICALLY VALIDATED PROGRAMS Every intervention XSpan delivers is grounded in clinical evidence and validated through partnerships with leading health systems and medical institutions. This is not wellness advice from an algorithm - it is evidence-based preventive medicine. Programs address the major drivers of chronic disease: Metabolic Health and Diabetes Prevention Cardiovascular Risk Reduction Obesity and Weight Management Stress and Behavioral Health Sleep Optimization AVAILABLE THROUGH YOUR PROVIDER XSpan is offered through health systems, hospitals, medical groups, and employer health plans as a preventive health benefit. Ask your doctor, HR team, or health plan if XSpan is available to you. CONNECTS TO YOUR WEARABLES Sync with Apple Watch, Oura Ring, Fitbit, Garmin, WHOOP, glucose monitors, blood pressure devices, and 200+ integrations. YOUR DATA. YOUR CONTROL. Your personal health data is never sold to advertisers, insurers, or third parties. Your data belongs to you. XSpan may participate in de-identified research to advance medical science, with your identity always protected. USED BY LEADING HEALTH SYSTEMS XSpan powers preventive health programs across major health systems and employer health plans. Extend your lifespan and healthspan with XSpan.
