DLJ Merchant Banking Partners (now aPriori Capital Partners) is a private equity firm focused on leveraged buyout transactions, originally founded as the merchant banking arm of Donaldson, Lufkin & Jenrette.

DLJ Merchant Banking Partners (DLJMB) was founded in 1985 as the private equity arm of the investment bank Donaldson, Lufkin & Jenrette. Initially established to invest capital alongside the bank's clients using balance sheet funds and employee contributions, the firm transitioned to raising institutional private equity funds in 1992. Following the acquisition of DLJ by Credit Suisse First Boston in 2000, the group underwent significant leadership changes and saw several high-profile teams spin off to form independent firms such as Diamond Castle Holdings and Avista Capital Partners.

The firm historically managed a diverse range of investment vehicles, including real estate, international private equity, growth capital, mezzanine debt, infrastructure, and energy-focused funds. Despite internal turnover, the firm continued to raise multi-billion dollar funds throughout the 2000s, including a $5.3 billion fund in 2000 and a $2.1 billion fund in 2006. In 2014, the firm officially spun out from Credit Suisse to become an independent entity renamed aPriori Capital Partners.

Throughout its history, the firm has maintained a significant presence in major financial hubs, operating offices in New York, London, Los Angeles, and Detroit. Its investment activity has spanned various sectors including retail, media, healthcare, and industrial manufacturing, often targeting large-scale leveraged buyouts of established companies.
