About Onos Health

Onos Health is a San Francisco behavioral-health clinical intelligence platform for health plans that uses proprietary AI to turn unstructured clinical documentation, claims and utilization data into actionable quality and care-pathway insights so payers can proactively partner with providers, reduce administrative delay and improve outcomes and affordability. Press cites gains including about 35% better clinical-standard adherence, 75% faster clinical review and more than 6% lower behavioral-health program costs within 12 months, and notes that more than 70% of behavioral-health quality signals sit in unstructured notes. Customers include Aetna and other large U.S. health plans; Onos says three of the six largest U.S. plans use the platform. Co-founded by CEO Akshay Agarwal, Onos in August 2026 raised a $17 million Series A led by Costanoa, with Flare Capital Partners and CVS Health Ventures, to accelerate adoption across health plans.
