TLDR: UST, a prominent digital transformation solutions company, is set to see its health insurance technology provider, HealthProof, merge with HealthEdge, a US healthcare software company recently acquired by Bain Capital. This strategic move, driven by significant capital and expertise from Bain Capital, aims to accelerate innovation in digital technologies, particularly in AI and GenAI enablement within the health plan sector. HealthProof, a UST-owned entity, generates $100 million in EBITDA and is expected to play a crucial role in enhancing HealthEdge’s service offerings and market reach.
UST, a global leader in digital transformation solutions, is embarking on a new phase of growth through a strategic transaction involving its health insurance technology subsidiary, HealthProof, and Bain Capital. While specific details of a direct investment in UST by Bain Capital on September 4, 2025, were not explicitly found, related reports from April 14, 2025, indicate a significant strategic alignment. Bain Capital recently acquired HealthEdge, a US healthcare software company, from Blackstone in a deal valued at approximately $2.6 billion, including debt. A core component of Bain’s strategy for HealthEdge involves the planned acquisition and merger of HealthProof, a UST-owned entity, into HealthEdge.
This partnership is poised to inject substantial capital and strategic expertise, enabling UST to expand its market presence, enhance its service portfolio, and accelerate innovation in cutting-edge digital technologies, with a particular emphasis on Artificial Intelligence (AI). Bain Capital partners Devin O’Reilly and Paul Moskowitz have articulated a clear vision for HealthEdge, expressing their hope that the company ‘can be a driving force for GenAI enablement at health plans.’ This strategic direction strongly aligns with UST’s stated goal of accelerating its innovation in digital technologies, including AI.
HealthProof, a long-standing partner of HealthEdge, is a robust health insurance technology provider that generates an impressive $100 million in EBITDA. The company further solidified its market position in 2022 through the acquisition of Advantasure, a technology firm specializing in government health programs. The integration of HealthProof’s capabilities with HealthEdge’s existing modernization software for healthcare insurers is expected to create a formidable force in the healthcare technology landscape.
Bain Capital’s investment in HealthEdge, at a hefty 30x EBITDA multiple of HealthEdge’s $86 million in earnings, underscores the private equity firm’s confidence in the growth potential, particularly fueled by AI advancements. This move is not Bain’s first venture into healthcare technology; the firm previously acquired Zelis, a healthcare payments administrator, in 2019, merging it with RedCard Systems to form a new company valued at $5.7 billion, which reportedly grew to $17 billion by September of the previous year. Such strategic mergers and leadership changes, including the installation of internal partners like Amanda Eisel as CEO and Brian Gladden as CFO at Zelis, are characteristic of Bain’s value creation process.
