Castle Harlan is a New York-based private equity firm specializing in buyouts and growth capital investments in middle-market companies.

Founded in 1987 by John K. Castle and Leonard M. Harlan, Castle Harlan has a history rooted in the early private equity activities of Donaldson, Lufkin & Jenrette. The firm focuses on acquiring controlling interests in middle-market companies across a variety of industries, including industrial services, consumer products, and energy. Since its inception, the team has completed over 50 acquisitions with a total value of approximately $10 billion.

Beyond its domestic operations, the firm expanded into the Asia-Pacific region in 1999 by partnering with Australian Mezzanine Investments to create Castle Harlan Australian Mezzanine Partners (CHAMP). The firm has raised several investment vehicles, including five U.S.-based funds and three Australian-based funds. Notable recent activity includes the acquisition of sunless tanning equipment manufacturer Sunless Inc. and the creation of Titan Production Equipment through the purchase of assets from Exterran Corporation.
