Adonis, a NYC-based provider of an AI orchestration platform for revenue cycle management (RCM), has raised $40 million in a Series C funding round led by Quadrille Capital.
The round also saw participation from existing investors General Catalyst and Bling Capital.
The company plans to use the funds to grow its operations and improve development.
The funding round brings Adonis’ total funding to over $95 million since its 2022 founding. In 2025, the company grew revenue more than 4 times and achieved a net retention of over 130%. This strong growth shows rising investor confidence in its technology, which helps solve key challenges in healthcare revenue operations.
The announcement comes at a key moment for the healthcare industry. Recent policy changes, including the One Big Beautiful Bill, have altered Medicaid and ACA subsidies, leading to more uninsured patients and more complex payments. With rising claim denials and changing insurance rules, healthcare teams are under increasing pressure to navigate a complex payment system.
Adonis, an AI platform for revenue cycle management, helps solve these challenges. Its AI tools track and identify issues, suggest actions, and automatically move claims toward payment. This helps healthcare organizations improve revenue, better handle insurer challenges, and reduce staff workload.

This Series C funding shows that improving revenue cycle performance is now a top priority in healthcare. Many health systems want better control and predictability, which older tools cannot provide. Adonis offers practical AI solutions that learn from millions of claims to improve collections, reduce unnecessary work and ease staff burden. Its system also includes human oversight, giving leaders confidence in using AI.
Before this, Adonis had raised over $54 million by early 2025, with investors like General Catalyst and Point72 Ventures. With the new funding, the company plans to improve its AI products, grow its presence in the healthcare market and expand its team in New York City.
“Mount Sinai Health System said that managing healthcare payments is becoming more complex due to changing insurance rules, higher claim denials, and staff shortages. They see Adonis as a strong partner that uses AI to identify important issues, improve financial results, and help teams focus on the most important tasks, setting a new standard for revenue operations.”
“Adonis CEO Akash Magoon said the pressure on healthcare organizations is growing, and this funding shows that investors support solutions to fix key problems like staff shortages, claim denials, and underpayments. He added that the company’s goal is to simplify revenue cycle management and help teams solve these challenges more efficiently using AI.”
“Amine Baji from Quadrille Capital said revenue cycle performance is now critical for financial stability in healthcare. He noted that Adonis’ AI platform can handle complex processes from identifying problems to solving them, and they are excited to support the company’s growth.”
