About Onos Health

Onos Health's mission is simple but ambitious: ensure every healthcare dollar goes toward delivering the highest quality care. Today, 30% of total U.S. healthcare spending is wasted due to ineffective care and administrative burden caused by misalignment between providers and payers. Onos is addressing this by building the largest AI-driven healthcare data platform. Our models enable payers to make faster, more accurate decisions across their populations. By guiding members to the right care, Onos is channeling more dollars to high-quality care that drives outcomes while making healthcare more affordable.

Onos recently closed a $6M Seed round with top-tier investors and is already working with some of the nation's largest health plans, signing its first national plan just months after launch. Join us to be part of a category-defining company and help reimagine healthcare for the better.
