Rosenberger, Langer & Cie. is a German multi-family office managing capital for entrepreneurs across real estate, funds, and alternative assets.
ROSENBERGER, LANGER & CIE.
Founded by Michael Rosenberger and Hans-Jürgen Langer, Rosenberger, Langer & Cie. operates as a multi-family office anchored in Bad Soden, Germany. The firm was built to address complex, intergenerational financial needs for wealthy families and entrepreneurs. It emphasizes long-term capital preservation, succession planning, and tailored advisory on family and business priorities. The co-founders continue to serve as Managing Partners, and in 2024 Hans-Jürgen Langer's son, Andreas Heinz Langer, was appointed Managing Director. The firm deploys capital across a deliberately diverse set of asset classes. Confirmed commitments include commercial property through a 12-unit portfolio in Germany, mixed-use development projects in the state of Hesse, and collectibles and passion assets. It also maintains exposure to rare earths and technology themes — AI/ML, consumer tech, and semiconductors — alongside fund-of-funds vehicles. Two Luxembourg-domiciled funds, RL&C – Global Dynamic Fund and RL&C – OneWorld Multi-Asset Fund, form part of the investment architecture. Geographic focus centers on Europe, with direct real assets concentrated in the Frankfurt region. Andreas Heinz Langer joined the firm as Managing Director in 2024, marking a deliberate step in generational leadership transition. The office is a member of the Verband unabhängiger Vermögensverwalter Deutschland e.V. and the Bundesverband für Wirtschaftsförderung und Außenwirtschaft, reflecting its integration into Germany's independent wealth-management community. Co-founder Hans-Jürgen Langer also serves on the board of the Haus- und Grundbesitzerverein Ffm.-Sossenheim e.V., the local property owners' association. The firm's Luxembourg fund platform, combined with direct real asset ownership and a family-led governance structure, distinguishes it from purely advisory multi-family offices. It operates simultaneously as an allocator and a direct principal in property and alternative assets. The involvement of the founder's next generation in day-to-day management underscores an active, multi-decade succession blueprint.

Frequently asked questions
Who runs investment decisions at Rosenberger, Langer & Cie.?
The firm is led by co-founders Michael Rosenberger and Hans-Jürgen Langer, who serve as Managing Partners. In 2024, Hans-Jürgen Langer's son, Andreas Heinz Langer, was elevated to Managing Director, signaling a next-generation transition in day-to-day oversight. Day-to-day portfolio construction spans direct real estate, fund selection, and thematic technology exposures.
How is the firm structured — as a single family office or a multi-family office?
Rosenberger, Langer & Cie. is structured as a multi-family office, serving multiple wealthy families and entrepreneurs from its Bad Soden headquarters. It combines traditional wealth-advisory functions with direct investment in real estate and collectibles, plus a Luxembourg-based fund platform that pools capital across clients.
Does the firm participate in fund commitments or only direct deals?
The firm uses both approaches. It makes direct investments in commercial real estate — including a 12-unit portfolio in Germany and mixed-use development projects in Hesse — while also operating two Luxembourg-domiciled fund vehicles: RL&C – Global Dynamic Fund and RL&C – OneWorld Multi-Asset Fund. This hybrid model allows it to blend direct asset control with diversified fund exposure.
What sectors and asset classes does the firm target?
Confirmed asset classes include commercial and mixed-use real estate, collectibles and passion assets, rare earths, and technology themes encompassing AI/ML, consumer tech, and semiconductors. The firm also commits capital through fund-of-funds structures, with a geographic emphasis on European, particularly German, investments.
Where does the underlying wealth come from?
The firm does not publicly disclose the specific wealth origins of its founding principals or client families. Its public footprint reflects a multi-client multi-family office model rather than a single-source fortune. The co-founders' involvement in local property-owner associations and independent wealth-manager networks suggests deep ties to the German Hesse and Frankfurt business communities.
