Investment thesis
BU-managed funds focus on mid-market leaders and hidden champions in the DACH region and neighboring markets. Through minority and majority stakes, the firm typically invests between EUR 100 million and EUR 500 million in equity, frequently in the context of company successions. Founders or sellers often retain a stake and sit on an advisory board, while managers become co-owners. BU tailors each investment program to the situation—succession, growth, carve-out, management buy-out (MBO), or management buy-in (MBI)—using flexible financing structures backed by deep capital-markets knowledge and an extensive expert network, with the aim of accelerating growth and creating lasting value.
