Overview

Hylas Holdings GmbH (Amtsgericht München HRB 117045) was founded in 1997 by Andreas Buchner and Thomas Leitermann as a joint holding company and was converted into a single family office from 2008; since 2017 the family has been its sole owner. In 2019 most of its direct stakes were merged with those of the Claudy family holding into Maffei GmbH & Co. KGaA, listed since 2024, in which Hylas holds 50% of the general partner and about 35% of the shares. It also manages liquid and illiquid assets (Hylas.Capital), family residential property, further stakes (Hylas.Investments, incl. the Proculus Verlag imprint), the Margarete-Franz-Stiftung and the Sammlungen Buchner art and book collections.
