Company Overview
About Adonis
Adonis is an AI-powered healthcare revenue cycle management (RCM) platform targeting the surging hospital denial crisis: payer denials are now the primary driver of healthcare revenue risk, with denial rates increasing year-over-year as commercial payers deploy more aggressive prior authorization and claims review protocols. The company raised $40 million in Series C financing in March 2026 led by Quadrille Capital and General Catalyst, bringing total funding to $95 million+ on the back of 4x revenue growth in 2025.
Business Model & Competitive Advantage
The platform's AI orchestration automatically researches denied claims, identifies the correct supporting documentation, and prepares appeals at scale — compressing a process that typically requires multiple days of manual research per denial into minutes per automated appeal. Clients including Mount Sinai, Baptist Health South Florida, and AdventHealth represent health systems where denial management has direct and material impact on annual revenue.
Competitive Landscape 2025–2026
With 130%+ net revenue retention, Adonis demonstrates that existing customers consistently expand their usage — the natural expansion path being from specific service lines (where RCM automation begins) to the full hospital system. The RCM automation opportunity is substantial: the average US hospital loses 1-3% of net patient revenue to preventable denials, and for a $2 billion health system that represents $20-60 million in recoverable revenue annually.
