Proof of Usefulness Score
Certified Problem Solver

Flexia Pilates is a legitimate, venture-backed hardware startup (raised $4M Seed in 2022 from ADvantage Sports Fund and Techstars) offering a smart Pilates reformer with AI-enabled sensors. Contrary to the submission's hyperbolic claim that 'most people have used my product', the actual user base is a niche but growing segment in the premium connected fitness market (est. revenue ~$1.7M). The project demonstrates high real-world utility and technical innovation (patent-pending sensors, Movement Quality Score) which distinguishes it from traditional equipment. However, the PoU score is constrained by the niche audience reach compared to mass-market platforms and the extremely poor quality of the submission data.
