Fit3D is a mature, revenue-generating business with a strong hardware/software moat and verified global traction (5k+ units, 5M+ scans). While the submission text contained hyperbolic claims ('everyone', 'most people'), external search confirms significant B2B partnerships (Gold's Gym, Equinox) and a robust subsidiary brand (WAIR). The project scores highly on utility, innovation, and traction, significantly outperforming the 'Response Quality' of the application itself.
