Industry Mainstay

Project is a legitimate, high-impact mental health AI company (rebranded to Cass) with verified reach of 29M+ covered lives (via insurance/EAP partnerships) and over 13,000 documented suicidal crisis de-escalations. While the submission's claim 'most people have used my product' is hyperbolic and the response quality was low effort (missing revenue/users), the underlying technology and clinical impact are substantial and verifiable via external sources (SFGate, multiple RCTs).
