Breidenbach von Schlieffen & Co.
Breidenbach von Schlieffen & Co. was established in Hamburg in 2013 by Dr. Marc Breidenbach and Magnus Graf von Schlieffen. Both founders arrived from long tenures advising entrepreneur families and institutional clients at major German and international banks. The firm constructs and monitors portfolios that combine private equity, real estate and digital assets. Mandates typically include direct holdings, external manager mandates and co-investments. Geographic exposure spans Europe, North America and Asia. Clients receive consolidated reporting, manager due diligence and succession planning without exclusive arrangements with any product provider. No recent operational events from the last 24 months appear in public records. Team size and AUM remain undisclosed. Adjacent vehicles include the Schlieffen family land, forestry and real-estate holding in Schloß Holte-Stukenbrock. The firm operates under BaFin authorization as a securities institution and maintains memberships in the VuV and Versammlung Eines Ehrbaren Kaufmanns zu Hamburg. This regulatory posture and network access distinguish its service model from unregulated advisory platforms.
