Arbiter Emerges from Stealth with $52M to Build the AI System that Connects Healthcare

Arbiter has announced its official launch from stealth with $52 million in funding, positioning itself as an AI-powered platform designed to unify payers, providers, and patients in a single care coordination system. The funding round, led by TriEdge Investments and MFO Ventures with participation from WindRose Health Investors and other private equity partners, values the company at $400 million.

Healthcare fragmentation is a persistent challenge, costing the U.S. system nearly one trillion dollars annually and delaying or preventing timely care. Arbiter’s mission is to resolve these inefficiencies by consolidating disparate technologies and stakeholders into a single, intelligent care orchestration framework that enables real-time collaboration and optimized decision-making.

At the center of Arbiter’s platform is its Record-Action-Alignment model, which establishes a longitudinal patient record integrating clinical, financial, and policy data. Using AI, the platform automates key actions and ensures synchronization among all parties involved in care delivery. The system’s first commercial application, real-time site-of-care optimization, is already operational through collaborations with a national payer and leading provider networks. It matches referrals to the most suitable providers based on cost, quality, and availability, while automating authorization, outreach, and scheduling tasks to reduce bottlenecks and eliminate handoff delays.

“Arbiter’s mission is nothing less than to rebuild the operating spine of U.S. healthcare,” said Michelle Carnahan, co-founder and CEO of Arbiter. “By aligning payers and providers around the needs of patients, we’re transforming healthcare from a fragmented set of parts into a connected system that works for everyone.”

Over time, Arbiter plans to expand its platform capabilities from reactive problem-solving to proactive management and predictive intelligence. The AI model aims to forecast hospital utilization, disease onset, and system-wide risk, enabling earlier interventions and more efficient resource deployment.

“Healthcare fragmentation isn’t an abstract problem—it’s deeply human,” said Dr. Clive Fields, board member and co-founder of VillageMD. “Every delay or missed connection represents a patient waiting for care that should already be underway. Arbiter is uniting the system around them, so care can move at the speed of need.”

The company’s leadership and investor network represent more than $25 billion in annual healthcare payments and oversee millions of patient lives. With expertise drawn from organizations including Cigna, UnitedHealth, Kaiser Permanente, One Medical, and VillageMD, alongside technology veterans from Meta, Apple, Google, and Amazon, Arbiter aims to establish a new infrastructure for connected, AI-driven healthcare delivery.
