MindDay develops a mental-health app based on cognitive behavioral therapy, offering more than 60 programs and over 300 interactive sessions that address issues from stress and sleep to depression and relationships. Since launch the company reports nearly two million downloads (including 600,000 in 2025) and more than 50,000 paying subscribers, with 100% growth between 2024 and 2025. The platform was developed in part with psychiatrist Hervé Montès and positions itself as a preventive, scientifically grounded complement to professional care. MindDay has moved toward a B2B2C distribution model, integrating in early 2026 with the Santéclair ecosystem to reach nearly ten million French people via partner mutuelles and insurers. The company ran a 2025 study with MGEN of 1,000 users that reported an average 38% improvement in wellbeing after six months of use. Plans include launching a complete English version imminently and prioritizing expansion into North America, contingent on reproducing its insurer/partner distribution model.
