• Onos Well being has raised $17 million in Sequence A funding led by Costanoa, with CVS Well being Ventures and Flare Capital Companions becoming a member of lower than a 12 months after its earlier spherical.

• The AI platform is reside with Aetna and three of the six largest US well being plans, claiming to chop behavioural well being program prices by greater than 6% inside 12 months.

• CEO Akshay Agrawal spent years advising the well being plans he now sells to, at Bain & Firm and Bain Capital, earlier than founding Onos in 2024.

Akshay Agrawal spent years on the opposite aspect of the pitch assembly, advising well being plan executives at Bain & Firm on the right way to run their companies higher. Now, those self same executives are paying his firm to repair an issue he watched them battle with from the within: behavioural well being knowledge that’s too messy for legacy methods to make use of.

Onos Health has raised $17 million in Sequence A funding led by Costanoa, with Flare Capital Companions and CVS Well being Ventures becoming a member of as traders. 

The spherical follows a $6.3 million increase Onos closed in October 2025, co-led by Haystack and Pathlight Ventures with Bertelsmann Healthcare Investments and Nebular collaborating, which means the corporate has now raised roughly $23.3 million in underneath a 12 months.

Turning medical information into actionable intelligence

Behavioral well being has grow to be the fastest-growing price driver for a lot of US well being plans for the reason that pandemic, and direct medical prices already exceed $140 billion a 12 months within the nation. Greater than 23% of US adults expertise a psychological well being situation yearly, but well being plans nonetheless lean on guide, retrospective chart evaluations to guage whether or not care was applicable.

Onos says greater than 70% of the alerts plans have to assess care high quality sit in unstructured documentation, together with session notes, therapy plans, and assessments, which its AI fashions are constructed to parse. 

As an alternative of a plan ready months for a retrospective audit to catch a supplier drifting from medical tips, Onos says its platform flags the sample in close to actual time. 

The corporate studies a 35% enchancment in medical customary adherence, a 75% enchancment in overview effectivity, and a discount of greater than 6% in behavioural well being program prices inside 12 months.

Behavioral well being knowledge platforms sit adjoining to a broader and more and more crowded value-based care analytics market, the place Innovaccer and HealthEdge already promote payer-facing instruments. 

In contrast to opponents, Onos educated its fashions particularly on behavioural well being documentation, a class that bigger distributors have traditionally folded into broader utilisation-management merchandise somewhat than handled as a definite self-discipline.

A founder who used to take a seat throughout the desk

Onos was based in San Francisco in 2024 by Agrawal, Josh Levitan, and Suhaas Prasad, and now has 18 workers. 

Agrawal’s background is squarely payer-side: after Bain & Firm, he moved to Bain Capital, investing in care supply platforms, then took working roles at mPulse, a member-engagement platform for well being plans, and Presence, a digital behavioural well being supplier for youngsters and faculties. 

Levitan brings 15-plus years of constructing expertise for well being plans and authorities healthcare applications, together with Medicaid initiatives comparable to Hawaii Med-QUEST and Wisconsin BadgerCare.

That pedigree seems to be precisely what drew CVS Well being Ventures in. The strategic investor has beforehand backed Thyme Care, an AI-powered most cancers care navigation startup that turned a unicorn on a $97 million increase, and Simile, a Stanford spinout that closed $200 million months after its Sequence A, each indicators that CVS’s enterprise arm favours founders who can transfer from early traction to enlargement rapidly.

Buyers see infrastructure alternative

“Behavioral well being care high quality is obscure and handle as a result of it’s recorded in unstructured medical documentation which legacy options can’t course of. AI has the potential to basically rework how well being plans handle care by making medical high quality and care pathways measurable at scale,” stated Agrawal, co-founder and CEO of Onos Well being. 

“Behavioural well being is among the largest and least understood classes in healthcare,” stated Amy Cheetham, associate at Costanoa. She stated the corporate is constructing “vital foundational infrastructure for behavioural well being care” that has traditionally been missed.

CVS Well being Ventures additionally sees a possibility to enhance how well being plans interpret advanced behavioural well being knowledge. “Onos Well being helps floor actionable medical insights from knowledge that has traditionally been tough to interpret,” added Alyssa Reisner, vice chairman and common associate at CVS Well being Ventures.

“Onos is giving well being plans the behavioural well being medical intelligence they should transfer from reactive oversight to value-driven healthcare. Well being plans utilizing Onos’ AI-powered platform are seeing important enchancment in medical high quality and affordability, and we’re excited to associate with Akshay and the crew as they construct the class,” concluded Margaret Malone, associate at Flare Capital Companions. 

Two funding rounds inside a 12 months is a sign. What Onos nonetheless has to exhibit is whether or not AI educated on medical documentation can shift outcomes and prices throughout a big, various inhabitants of well being plans, or whether or not, like many category-defining bets in payer tech, the toughest half will not be the mannequin however getting entrenched well being plans to alter how they work.
