Overview
Twin Health has built the Whole Body Digital Twin, a continuous digital model of an individual's metabolic physiology constructed from continuous glucose monitors (CGM), wearable sensors, blood biomarkers, and lifestyle data. The platform's AI analyzes over one million data points per person per day to build a personalized metabolic model that predicts how each individual responds to food, sleep, exercise, stress, and medication changes. Based on these predictions, Twin's coaching platform — delivered via a dedicated health team and mobile app — guides patients through precision nutrition, lifestyle, and behavioral interventions uniquely tailored to their digital twin. Health systems, employers, and payers deploy Twin Health's platform for patients with type 2 diabetes, pre-diabetes, obesity, and metabolic syndrome. Clinical outcomes data published in peer-reviewed journals demonstrates that 54% of Twin Health patients achieved type 2 diabetes remission (defined as HbA1c below 6.5% without diabetes medications) after one year — a result that significantly outperforms standard diabetes care and comparable to bariatric surgery outcomes. The platform has been deployed across major health systems in the United States and India. Twin Health's approach differs from other diabetes management platforms by treating metabolic disease as a precision medicine problem requiring individual-specific optimization rather than population-average guidelines. The Whole Body Digital Twin enables clinicians to test interventions virtually before implementation and continuously refine the model as new physiological data arrives. The company has raised over $140 million from investors including ICONIQ Capital, Sequoia Capital India, and Sofina, and holds regulatory clearances for its clinical programs across multiple markets.
