Flex AI has ceased active operations, confirming that its efforts to sell the company failed and its funding was exhausted. Co-founder and CEO Amin Niri informed employees and contractors of the shutdown in March 2026, stating that the startup would liquidate remaining assets and handle outstanding payments due to workers.
The closure marks a significant operational constraint for early-stage health tech companies attempting to monetize specialized AI features like real-time, on-device computer vision for exercise form feedback. While the overall global fitness app market is large, projected to generate $3.4 billion in annual revenue by 2025, the sector remains intensely saturated, presenting major challenges related to user retention and high market competition.
The closure suggests that even innovative, specialized AI features like on-device vision are insufficient to sustain a business in an oversaturated and capital-intensive health tech market without clear monetization pathways.
Flex AI had built an application offering workout tracking, AI-driven form correction, and a personalized AI persona for fitness guidance. The company previously reached nearly one million users and was noted for its innovative use of on-device processing. However, Niri acknowledged the difficulty of building sustainable businesses in crowded categories, citing economic challenges in specific markets.
The shutdown impacts not only former employees but also contractors who reported difficulties receiving payments for work dating back to January. The company eventually addressed these outstanding obligations directly through personal family loans when corporate funds were unavailable.
