Gainline Capital Partners LP, a private equity firm that invests in U.S.-based lower middle-market companies, has closed its $400 million second fund, Gainline Equity Fund II LP.

Gainline targets fundamentally sound businesses with proven business models, stable and mature revenue bases, prospects for substantial returns and which stand to benefit from Gainline’s management approach. Gainline had targeted $300 million for this fund with a hard cap of $400 million. The $400 million closing marks a 258 percent increase in the size of Fund II over Gainline Equity Fund LP, which closed in 2019. Gainline has already deployed $106 million in two Fund II investments.

Credit Suisse acted as placement agent for Gainline Equity Fund II LP and Willkie, Farr & Gallagher LLP provided legal counsel.
