Adonis Secures $40 Million Series C to Scale AI-Driven Revenue Cycle Platform

New updates have been reported about Adonis.

Adonis has raised $40 million in a Series C round led by Quadrille Capital, lifting total funding since its 2022 launch to more than $95 million and validating its position as an AI-native revenue cycle management platform for healthcare providers. The company reported more than 4x revenue growth in 2025 and net retention above 130%, signaling strong product-market fit as hospitals and health systems seek tools to stabilize financial performance amid mounting reimbursement complexity.

Adonis plans to use the new capital to accelerate development of its Intelligence, AI Agent, and Orchestration products, deepen penetration in the health system segment, and expand its New York–based team. Management positions the platform as an end-to-end AI orchestration layer that monitors revenue operations, flags root-cause issues, recommends actions, and autonomously advances claims, aiming to counter rising denial rates, workforce shortages, and underpayments that threaten provider margins.

The funding comes as recent policy changes, including the One Big Beautiful Bill’s impact on Medicaid and ACA subsidies, increase the number of uninsured and self-pay patients and complicate reimbursement rules. Against that backdrop, Adonis is pitching its technology as a way for RCM and finance leaders to regain predictability, reduce manual rework, and improve cash collections by leveraging models trained on millions of claims.

Health systems such as Mount Sinai report that Adonis’ platform helps them prioritize high-value exceptions and redeploy staff toward the most financially impactful work, illustrating how AI-enabled workflows can mitigate operational strain. For CIOs and CFOs cautious about AI risk, Adonis emphasizes a human-in-the-loop design and governance features intended to provide auditability and control.

Quadrille Capital’s participation, alongside existing investors including General Catalyst and Bling Capital, underscores investor conviction that revenue cycle performance is now a strategic lever for provider solvency, not a back-office function. For Adonis, the Series C represents both growth capital and a mandate to scale its orchestration model as AI adoption in healthcare accelerates.

Execution risk will center on product differentiation and integration depth with health system workflows, but if Adonis can maintain growth and retention metrics while proving sustainable ROI, it is positioned to be a key infrastructure provider in the next generation of RCM. The company’s focus on automating complex workflows from issue detection through resolution could make it a critical partner for providers seeking to offset reimbursement pressure and protect margins over the next cycle.
