Liesner & Co

Liesner & Co

Founded in 2012 by Jan-Henrik Supady, Dr. Jörg Liesner and Eric M. Balzer, the firm operates from offices in Hamburg, Kassel and Düsseldorf. Its 27-person team serves wealthy families, foundations and medium-sized enterprises, advising on asset controlling, succession planning and real-estate management. The three managing partners own and run the firm, which presents itself as deliberately independent — its website stresses that a family office is only independent when the company and its individuals answer solely to the asset owner. Liesner & Co structures bespoke portfolios across public and private markets with an emphasis on long-term capital preservation. Asset-class coverage spans real estate, private equity, private credit, hedge funds, natural resources and agricultural and forestry holdings. The firm makes direct co-investments and participates in fund-of-funds structures. Its thematic focus tilts toward ClimateTech and the energy transition; Jan-Henrik Supady holds a supervisory-board seat at SMA Solar Technology AG, Germany's largest solar-equipment manufacturer, connecting the office directly to the renewables supply chain. Geographic coverage extends across Europe and North America. The firm reports a headcount of 27 professionals across its three German offices and recently disclosed that it had offset 285 tonnes of CO₂ emissions generated by its own operations — a small but observable signal of its ESG posture. Its real-asset footprint includes commercial properties in Hamburg, such as the Tarpen 40 business park and a building on Essener Straße, alongside Valvo Beteiligungs GmbH. Liesner & Co participates in pemacom, a German private equity and M&A community, and maintains ties to the Hamburgische Kulturstiftung and the Foundation of the Friends of the HfMT. What makes Liesner & Co structurally distinct is the dual role its managing partner Jan-Henrik Supady plays: he both leads investment decisions at the family office and represents shareholder interests on the board of SMA Solar Technology AG. That alignment gives the firm a level of operational proximity to a sizable industrial asset that most multi-family offices — which typically take fund interests or minority co-investment stakes — do not enjoy.
