The owners of the two holding companies (Quadrat Capital GmbH and Sycamore GmbH), Matthias Woestmann, Thomas van Aubel, Jutta Freifrau von Falkenhausen, and Dinnies von der Osten, have a history of profiting from investments in companies that fail spectacularly and under suspicious circumstances. They and their associates are linked to a long list of companies involved in some of Germany’s largest financial scandals, including IGB, Balda (renamed to Clere), Q-cells, and Solon."
