Journeys Metabolic

Seed Round in 2019
Journeys Metabolic is a digital therapeutic platform that extends metabolic care from the clinic into the home. Its interoperable program is designed to address obesity and insulin resistance-related conditions by enabling health systems and accountable care organizations to transition toward value-based or fee-for-outcomes models with reduced provider burden. Grounded in several years of behavior modification, the physician-developed program integrates AI-enabled precision pathways, education through computer vision-enabled food analysis, and a proprietary biomarker of fat oxidation (Biosense) to guide nutritional interventions. The platform is HITRUST and EHR interoperable, supporting shared savings optimization across metabolic diseases and nutrition-related disorders. The approach emphasizes sustained lifestyle changes delivered over multi-month periods and aims to improve overall health outcomes while simplifying care delivery for clinicians and care teams.
