Wrnch

Niche innovator in AI-powered human pose estimation and motion tracking, acquired to bolster digital health MSK capabilities

Wrnch was a Canadian AI startup founded in Montreal that developed cutting-edge computer vision technology for real-time human body motion analysis and understanding. The company built deep learning-based pose estimation and motion intelligence solutions capable of tracking human skeletal movement from standard video input — without the need for specialized hardware like depth sensors or motion capture suits. Its technology had broad applicability across industries including sports performance, fitness, healthcare, gaming, and industrial safety. Wrnch's flagship technology centered on its AI-powered human pose estimation engine, which could accurately detect and track body keypoints and joint movements in real time from monocular video. This made it particularly attractive for applications requiring scalable, cost-effective motion analysis. The company positioned itself as a developer-friendly platform, offering APIs and SDKs that allowed third parties to integrate human motion intelligence into their own products and workflows. In 2021, Wrnch was acquired by Hinge Health, a leading digital musculoskeletal (MSK) clinic and one of the most highly valued digital health companies in the United States. Hinge Health acquired Wrnch specifically to enhance its motion tracking and movement analysis capabilities within its physical therapy and MSK care platform. Following the acquisition, Wrnch's technology and team were absorbed into Hinge Health, and the Wrnch brand no longer operates as a distinct entity. The acquisition underscored the growing strategic value of AI-driven human motion intelligence in digital health and rehabilitation.
