Hinge Health

Hinge Health is the dominant digital musculoskeletal (MSK) platform in the US. Founded in 2015 by Daniel Perez and Gabriel Mecklenburg in San Francisco, the company delivers smartphone-based exercise programs, AI motion tracking that provides real-time form feedback, and human care navigators including PTs, board-certified pain coaches, and orthopedic surgeons. Hinge Health covers over 19 million people through employer benefit programs and went public on the NYSE in 2025. The company's positioning is digital-first MSK care — back, neck, joint, and pelvic-floor pain treated through smartphone-supervised home exercises rather than in-clinic physical therapy. Employers pay Hinge to enroll their employees, replacing or augmenting traditional PT benefits with a measurably-cheaper digital alternative. The AI motion-tracking technology was developed in-house and competes directly with Kaia Health's similar capability — users prop their smartphone against a wall and the camera-based AI watches their form during exercises, flagging incorrect form, counting reps automatically, and adjusting exercise difficulty in real-time. Optional Hinge Connect Bluetooth motion sensors clip to the body for higher-fidelity form data on exercises where smartphone camera doesn't work. Beyond AI-driven exercises, Hinge Health employs licensed PTs, board-certified pain coaches, and orthopedic surgeons who interact with users via in-app messaging and video calls — the human-AI hybrid is the main differentiator versus pure-app competitors. Surgery decision support consults users considering joint replacement, ACL reconstruction, or back surgery on whether surgery is genuinely warranted. Pelvic floor rehab is the fast-growing women's-health expansion segment.
