About Onos

We’re transforming healthcare from reactive to proactive

Behavioral health is a top 3 challenge for health plans. Fractured systems and fragmented data have turned payers’ work into a defensive utilization management and cost containment effort. Onos is the behavioral health clinical intelligence platform that brings clarity to care quality and utilization, so health plans can proactively identify the optimal care pathways for members that deliver the best outcomes more affordably.

From the founders

Founded by operators who turn AI into outcomes

Healthcare is built around a system of highly manual, retrospective reviews and authorization processes. Fractured systems and fragmented data have turned payers’ work into defensive utilization management and cost containment efforts. This comes with a high operational burden that drives up costs and prevents payers and providers from collaborating to deliver the highest quality care to members.

At Onos, we believe in a better, more proactive approach. We have deep experience building AI products that deliver tangible business outcomes, and we’re applying this expertise to address an area that has become a major cost trend for health plans: behavioral health. More specifically, we believe in a world where everything in behavioral health isn’t managed exclusively through UM.

We have assembled a panel of behavioral health industry experts to guide the evolution of Onos and ensure that our platform is perfectly attuned to the needs of payers and providers. In partnership with our advisors, we’re identifying opportunities to enable seamless payer-provider collaboration, drive better outcomes, and lower cost of care—with AI as the central mechanism.

The result is Onos, the clinical intelligence platform purpose-built for behavioral health that brings clarity to clinical quality and utilization management, so health plans can proactively partner with providers to maximize health outcomes and affordability.
