About Onos Health

Onos Health's mission is simple but ambitious: ensure every healthcare dollar goes toward delivering the highest quality care. Today, nearly 30% of U.S. healthcare spending is wasted due to ineffective care and administrative burden, driven by misalignment between providers and payers. This waste is a primary reason healthcare remains unaffordable for so many.

Onos is addressing this by building the largest AI-driven healthcare data platform for clinical decision-making. Onos’ models help health plans make faster, more accurate decisions across their populations. The result is less friction between plans, providers, and members, better outcomes, and more affordable care.

• Meaningful impact: Help fix what is fundamentally broken in healthcare

• Direct collaboration: Work alongside experienced founders with deep healthcare and data expertise

• Culture: Join a high-performing, transparent, and results-oriented team

• Ownership: Significant responsibility and autonomy from day one

• Opportunity: Play a pivotal role in building a fast-growing, category-defining healthcare AI company
