Onos Health is a San Francisco-based company founded in 2024 that builds AI-powered software for health plans managing behavioral health programs. Its platform helps payers distinguish necessary from wasteful care, route members to appropriate clinical pathways, identify cost leakage, and track both member progress and provider care quality across the full spectrum of behavioral health diagnoses and care settings.
At the core of the platform is a proprietary AI/ML model trained on millions of claims, plan policies, clinical notes, and member data points. The model is available as a HIPAA-compliant, locally hosted deployment, allowing health plans to generate actionable clinical insights without exposing sensitive member data to external systems. The platform automates clinical and quality review workflows, with reported outcomes including a 50–60% improvement in review efficiency, a 3–5% reduction in total clinical behavioral health spend, and a 2x improvement in network satisfaction.
Onos Health raised a $6.32M Series A round, with investors including Haystack and Pathlight Ventures. The company signed its first national health plan client within months of launch and is working with several of the largest health plans in the United States.
The company was founded by healthcare and technology experts with a stated mission of directing every healthcare dollar toward the highest-quality care. Its technical focus spans AI and machine learning, claims data analysis, clinical notes processing, plan policy analysis, and on-premises model deployment.
