J.F. Müller & Sohn AG is an investment holding and family office in Hamburg, Germany, founded in 1795. It works as a long-term participations vehicle, taking direct equity stakes through its holding structure in "Old Economy" industrial assets and in digital businesses. The legal seat and registration are in Hamburg (HRB 2346), with a listed address on Klopstockstrasse. Leadership includes Raetke Müller (Vorsitzender) and Raphael Söhngen (Vorstand). Public records show a tracked Series A in Kiwi in March 2015 and an exit from Drooms in June 2026, and corporate listings link the group to port and terminal interests within the EUROGATE/Eurokai scope. Its activity profile points to direct-equity, holding-company participations, not a publicly marketed pooled fund. Multi-century family ownership, a Hamburg base, and a blend of industrial and digital investments make it a potential long-horizon, strategic partner for sponsors seeking a European investor with industrial capability.
