Business model
Folmer raises and manages private equity funds from institutional and professional investors and acquires majority or significant stakes in Finnish SMEs, then develops them with the sitting management team before exiting to strategic or financial buyers. Portfolio companies are also used as platforms for add-on acquisitions, as with ProMart's purchases of Ruuvilinja and Kuopion Tekniikka, Umacon's acquisition of Romuta, Donier Gastronomie's acquisition of Cheese Witches, and Finnsiirto's acquisitions of Simeri and Suomen Telakone.
Management of private equity funds on behalf of institutional and professional investors, with returns generated from the development and eventual sale of majority-held portfolio companies.
Traction
