Thompson Street Capital Partners

Thompson Street Capital Partners, based in St. Louis, is a middle-market private equity firm that partners with founders and managers to scale specialized businesses, including healthcare service platforms in the care delivery and tech-enabled services category. The firm’s healthcare focus skews toward operating businesses with clinical, ancillary, or outsourced service models rather than core software. Thompson Street is not flagged as an AI-themed investor, so AI-enabled physician tools should be positioned as productivity or quality enhancements within an underlying services thesis rather than the central value proposition.

Check sizes typically fall in the $5M to $25M range at the growth stage, consistent with a lower-to-middle-market mandate. The firm is geographically anchored in the central United States but invests broadly across North America. Typical transactions include majority recapitalizations, founder-led buyouts, and add-on acquisitions inside platform investments. Companies that fit Thompson Street’s profile generally have demonstrated profitability, defensible local or regional market positions, and a runway for organic and acquisitive growth.

Founders approaching Thompson Street should be prepared to discuss operational metrics, payer mix where relevant, and the playbook for adding sites, providers, or services. Limited public information is available on the firm’s specific intake preferences for technology-led pitches, so working through healthcare-focused investment bankers or leveraging board-level introductions tends to be the most effective route into a preliminary conversation.
