Middle-market private equity firm Thompson Street Capital Partners recently closed its fourth fund, TSCP IV, with $640 million in capital. The fundraising began in September and exceeded the initial target range of $500 million. 

Thompson Street, founded in 2000 and based in St. Louis, Missouri, focuses on founder-led targets in the middle-market that have up to $15 million in Ebitda across the health care, engineering and business services sectors. Some of the firm’s current investments include Logan’s Linens, which rents linens to health care facilities, and building products manufacturer Stone Panel.

“We are confident that our focus on founder-led businesses and deep expertise in the business services, health care and engineered products industries will continue to help businesses accelerate growth,” says Thompson Street managing partner Jim Cooper.

PE firms have been actively raising funds lately. Ardian raised a $1.1 co-investment fund; Audax Group closed its fifth PE fund; and Revelstoke Capital Partners LLC recently raised its first fund.

Park Hill was TSCP IV’s placement agent.
