Onos Health, a behavioral health clinical intelligence platform for payers, announced Wednesday that it raised $17 million in Series A funding.
The San Francisco-based company’s AI-powered platform analyzes structured and unstructured behavioral health data to identify care patterns, treatment gaps and where quality can be improved. Payers can use these insights to collaborate with provider networks while improving outcomes and reducing costs. It works with numerous commercial insurers, including Aetna.
The Series A funding round was led by Costanoa, with support from Flare Capital Partners and CVS Health Ventures. It comes after a $6.3 million seed round in October 2025 co-led by Haystack and Pathlight Ventures. In total, the company has raised $23.5 million to date.
“Behavioral health populations are often complex and require dedicated focus and coordination with health care providers to improve outcomes and affordability,” said Alyssa Reisner, vice president and general partner at CVS Health Ventures, in a statement. “Onos Health helps surface actionable clinical insights from data that has historically been difficult to interpret. It provides a clearer understanding of treatment patterns and quality of care and supports more informed decision-making and collaboration with behavioral health care providers.”
The financing will be used to accelerate adoption of Onos’ platform among health plans, grow its team and continue building out its AI infrastructure, the company told MedCity News.
More than 23% of U.S. adults battle a mental illness, while annual U.S. spending on mental health and substance use disorder treatment has reached nearly $140 billion. Behavioral health is a large and complex area of healthcare, but health plans often lack the tools to make sense of clinical data needed to assess care quality, according to Akshay Agrawal, co-founder and CEO of Onos Health.
“As a result, plans often lack visibility into whether members are receiving the right care, leading to reactive oversight (significant amounts of prior auth), administrative burden and delays in care,” he said. “Onos uses AI to turn fragmented data into actionable clinical intelligence, helping health plans identify treatment gaps, reduce reliance on reactive measures, improve care quality, and guide members toward better, more cost-effective care.”
The Onos Health platform can improve clinical standard adherence by 35% and clinical review efficiency by 75%, according to the announcement. It can also reduce behavioral health program costs by 6% within a year.
Other behavioral health technology companies include Lucet, NeuroFlow and Carelon Behavioral Health.
