Long Tail, a Chicago-based AI-native healthcare technology company focused on utilization management and physician advisory services, has received a strategic growth investment from Eir Partners Capital. Financial terms of the transaction were not disclosed.
Founded in 2023, Long Tail develops software and services designed to help hospitals, medical centers, and health systems navigate payer complexity. Its platform leverages proprietary payer intelligence and AI-driven automation to improve reimbursement outcomes, streamline denial workflows, and reduce operational costs tied to utilization management and physician advisory programs.
The company’s approach centers on aggregating insights from a growing network of providers and physicians, enabling healthcare organizations to better understand payer behavior and optimize revenue cycle performance. By targeting utilization management, a key driver of high-cost claim denials, Long Tail aims to address one of the most significant inefficiencies in healthcare operations.
The new investment will support continued product innovation, expansion of Long Tail’s proprietary data network, and scaling of its go-to-market capabilities as demand increases across health systems. Eir Partners Capital, a Miami-based private equity firm focused on healthcare technology and tech-enabled services, typically invests in growth-stage companies and works closely with management teams to build scaled platforms across payer, provider, employer, and pharmaceutical sectors.
