Onos Health raised $17 million in a Series A round to expand its AI-powered behavioral health platform. The round was led by Costanoa with participation from Flare Capital Partners and CVS Health Ventures, reflecting continuing investor appetite for clinical workflow tools in mental health settings. The company’s platform is positioned to scale behavioral health delivery using AI-driven assessment and engagement workflows. The financing is intended to support product expansion and operational growth. The deal underscores that, even as oncology and immunology dominate headlines, investors continue to fund AI systems designed to integrate into care pathways where access and continuity remain key constraints.
