DLJ Merchant Banking Partners (now aPriori Capital Partners) is a private equity firm originally founded as the investment arm of Donaldson, Lufkin & Jenrette.

DLJ Merchant Banking (DLJMB) was established in 1985 as the merchant banking arm of Donaldson, Lufkin & Jenrette to invest capital in leveraged buyouts alongside the bank's clients. The firm transitioned from investing off the bank's balance sheet to raising institutional private equity funds, including a $5.3 billion fund in 2000. Following the acquisition of DLJ by Credit Suisse First Boston, the firm saw significant leadership turnover and several high-profile spin-outs, including the formation of Diamond Castle Holdings and Avista Capital Partners.

In 2014, DLJMB was officially spun out from Credit Suisse to become an independent firm known as aPriori Capital Partners. Throughout its history, the group managed a diverse range of investment vehicles covering real estate, international private equity, growth capital, and mezzanine debt. The firm maintains a presence in major financial hubs including New York, London, and Los Angeles.
