Doughty Hanson & Co is a London-based European investment manager founded in 1985 that historically focused on private equity, leveraged buyouts and recapitalization transactions in mid-market companies across Europe, with additional investing activities in real estate and early-stage technology ventures; the firm has completed more than 100 investments since inception and has operated separate fund strategies across private equity, real estate and technology, though in recent years it rebranded as DH Private Equity Partners and scaled back broader fundraising efforts to concentrate on core buyout activities.
