Liesner & Co
Liesner & Co is a Hamburg-based multi-family office founded in 2012 by Jan-Henrik Supady, Dr.
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.

Frequently asked questions
Who runs investment decisions at Liesner & Co?
The three founding managing partners — Jan-Henrik Supady, Dr. Jörg Liesner and Eric M. Balzer — jointly oversee investment decisions. Supady's operational proximity to SMA Solar Technology AG, where he serves on the supervisory board, adds a direct corporate-governance layer to the firm's investment process. Day-to-day asset allocation and portfolio work is supported by senior investment consultants including Nicole Schomburg and Lena Christina Heß, who specialize in liquid allocations and private equity, respectively.
Is Liesner & Co a single-family office or does it operate more like an investment firm?
Liesner & Co is structured as an independent multi-family office — it serves multiple wealthy families, foundations and medium-sized enterprises, not a single fortune. The firm emphasizes its independence in marketing materials, stating that its decisions are made solely for the asset owners. Unlike many multi-family offices that function as asset gatherers, Liesner & Co maintains a deliberately compact team of 27 and also holds direct commercial real estate on its own account.
What is Liesner & Co's connection to SMA Solar Technology AG?
Managing partner Jan-Henrik Supady holds a supervisory-board seat at SMA Solar Technology AG in his capacity as a shareholder representative. This board position gives Liesner & Co direct exposure to listed German renewable-energy infrastructure and signals the firm's deep commitment to the energy-transition sector.
Does Liesner & Co participate in fund commitments or only direct deals?
The firm uses a blend of direct co-investments, special-purpose vehicles, fund-of-funds commitments and allocations to hedge funds. It also holds physical real estate, agricultural and forestry properties directly. This combination allows it to tailor portfolios for clients who require both liquidity management and long-duration illiquid exposure.
Which sectors does Liesner & Co explicitly focus on?
Confirmed sector concentrations include ClimateTech, Energy Transition & Renewables, and AgriTech & FoodTech, alongside traditional asset classes such as real estate, infrastructure, private credit and hedge funds. The firm's website and published insights also emphasize ESG integration and impact investing across its mandates.
How is Liesner & Co's philanthropic activity structured?
Liesner & Co maintains relationships with the Hamburgische Kulturstiftung and the Foundation of the Friends of the HfMT. It does not disclose whether these are client-related or internally funded, but the firm markets its work to foundations and charitable entities, suggesting philanthropy is both a client mandate and a personal commitment of the partners.
What is Liesner & Co's posture on co-investments alongside external GPs?
Liesner & Co's private-market exposure includes direct co-investments and SPVs, indicating it will underwrite individual deals alongside general partners rather than relying solely on blind-pool fund commitments. The firm's membership in pemacom, a private equity and M&A networking community, facilitates the deal flow necessary for such co-investment activity.
