Hinge Health is a digital musculoskeletal (MSK) care platform that delivers physical therapy remotely through a mobile app, AI motion-tracking technology, and a care team of licensed physical therapists, physicians, and health coaches. The core product guides members through personalized exercise therapy programs across 16 body areas — including back, knees, hips, and shoulders — using Hinge Health's proprietary AI motion-tracking technology (TrueMotion) to provide real-time feedback on form. Hinge Health also distributes Enso, a wearable electrical nerve stimulation device, to higher-risk members to manage pain. Customers are primarily self-insured employers who offer the platform as an employee benefit to reduce MSK-related medical costs. Hinge Health had roughly 24.6M contracted lives across over 2,800 clients as of year-end 2025. Hinge Health charges clients per enrolled and engaged member, with revenue driven by contracted lives, the percentage of eligible lives that enroll and engage (yield, ~3.9% at year-end 2025), and price per engaged member. Gross margins are high because AI automates much of the work that would otherwise require physical therapist time. In 2025, Hinge Health served 47% more members while keeping care team costs flat. Growth is driven by expanding contracted lives, increasing yield within the existing base, and upselling new products — most notably HingeSelect, a vetted in-person network of physical therapists and orthopedic specialists launched in 2025 to complement the digital platform.
