Flex Capital
Oct 2018
Wir glauben, dass Deutschland nicht nur ein Land der Ingenieure, sondern auch ein Land der Programmierer ist. Hierzulande gibt es über 11.000 mittelständische Software- und Internetunternehmen, die sich aus eigener Kraft zu wachstumsstarken und profitablen, mitunter Weltmarktführern, entwickelt haben. Als „digitales Rückgrat“ leisten diese Tech-Pioniere die Innovationsarbeit, die unseren Wohlstand auch in Zukunft gewährleisten werden. Darin wollen wir sie unterstützen – mit Investitionen und Know-how. FLEX Capital ist ein Private Equity Fonds, der von erfolgreichen Serienunternehmern gegründet wurde und in profitable und wachsende Unternehmen aus dem deutschen Internet- und Software-Mittelstand investiert. Der Anfang 2023 verkündete zweite Fonds in Höhe von 300 Millionen Euro enthält erstmalig eine gewerbliche Struktur, die es FLEX Capital ermöglicht, Portfoliounternehmen mit einem eigens aufgebauten 30-köpfigen Expertenteam operativ zu unterstützen, wodurch sich der Investor von vielen anderen Private Equity Fonds unterscheidet.
