Summary
Karpel Solutions, a St. Louis-based software company that develops case management systems for prosecutor offices nationwide, has completed its first institutional private equity investment with Thompson Street Capital Partners (TSCP), a local PE firm. The transaction marks a significant inflection point for the company, which was founded in 1985 by Jeff Karpel and has established itself as a mission-critical infrastructure provider in the criminal justice technology space.

In connection with the investment, Todd Hicks has been named Chief Executive Officer, taking on expanded leadership responsibilities for the company's growth strategy. According to company announcements, Hicks brings more than 20 years of experience leading and scaling software businesses serving highly regulated industries. His appointment signals TSCP's intent to accelerate Karpel's market expansion and operational scaling under professional management. Founder Jeff Karpel, who previously served as CEO, remains involved with the company and expressed enthusiasm for the partnership with TSCP.

Thompson Street Capital Partners' investment in Karpel reflects the firm's focus on acquiring and scaling software solutions serving specialized, high-regulation end markets. The PE firm's involvement underscores growing investor appetite for software-as-a-service platforms that support critical government and law enforcement operations, where switching costs and customer stickiness create stable, recurring revenue streams.

The transaction was facilitated by investment banking advisors Raymond James and Lewis Rice, indicating institutional-quality deal infrastructure. This represents a transition from Karpel's founder-led operational model to a more structured growth capital approach, typical of PE-backed software acquisitions targeting further market penetration and geographic expansion.
