## About

The Karg-Stiftung was established in 1989 by Hans-Georg Karg and his wife Adelheid. Hans-Georg Karg was the son of Georg Karg, owner of the Hertie department store chain. The foundation focuses on reshaping German education systems to identify and develop highly gifted children from kindergarten through secondary school. Capital deployment centers on buyouts and a legacy private equity portfolio. Real estate assets include Seeresidenz Alte Post in Seeshaupt, Residenz am Heilig-Geist-Park in Potsdam, and Gut Sossau in Grabenstätt. The foundation also holds the Hans-Georg Karg Collection and the Max Liebermann Collection. Geographic reach stays within Germany, with program activity nationwide and asset holdings concentrated in Bavaria, Brandenburg, and Hesse. Trutz Rendtorff serves as CEO and Chief Investment Officer. Ingmar Ahl acts as Chairman of the Board while also serving on the advisory board of the Bundesverband Deutscher Stiftungen. The foundation maintains membership in that industry association. No operational events from the last 24 months appear in available records. Asset management occurs through the separate vehicle Karg Vermögensmanagement GmbH, which handles securities and participations. This separation creates a distinct governance layer between investment execution and program delivery.
