## About

Martin Widerker established the firm in the 1970s. He financed early property acquisitions through parallel ventures in building cleaning and wholesale. His wife Karolina Widerker participated from the outset. Sons Bernard Dov Widerker and Benny B. Widerker joined in 1989 and 2006 respectively and now share managing director responsibilities. The office invests directly in four asset classes: retail, office, logistics and hospitality. It executes development projects and ongoing management through two internal vehicles, bc Boden-Commercial-Immobilien and Widerker Investment Management. Confirmed holdings include Wiener Platz 1 in Stuttgart and Schlosspark-Passage in Berlin-Buch. All activity remains inside Germany and other European markets. The structure favors direct ownership and co-investments over fund commitments. The firm reports more than 50 years of experience and states that over 1,000 employees work across its portfolio companies. It operates offices in Stuttgart and Berlin. Martin Widerker has served on the board of the Israelitische Religionsgemeinschaft Württembergs since 1968. No new operational events have been recorded in the last 24 months. Ownership stays entirely within the Widerker family. This arrangement keeps investment decisions, risk allocation and governance inside one household, eliminating external LP reporting cycles and allowing multi-decade hold periods on individual assets.
