Sentinel Capital Partners, a private equity firm, has acquired a majority stake in TriMech, an engineering services firm, from The Halifax Group, a middle-market private equity firm.

TriMech sells and services engineering and manufacturing-related software and additive manufacturing hardware and supports 3D modeling, simulation, and virtual replication. The firm is a technology and business services provider that serves more than 15,000 active clients.

“Working together, we were able to expand TriMech’s solution offering into new products and services as well as new geographies, creating a more complete solution provider for TriMech’s customers,” said David Bard, partner at Halifax. “The advanced engineering and manufacturing sector is seeing significant growth, and we believe the company is well-positioned to meet a wide array of customer needs through its innovative products, best-in-class service, and operational excellence.”

Piper Sandler served as a financial advisor, Stifel served as a co-financial advisor, and Arnold & Porter, Perkins Coie and Borden Ladner Gervais served as legal advisors to Halifax and the company.
