Münster Stegmaier Rombach Family Office

Stephan Jäggle serves as Chief Investment Officer and Managing Partner, responsible for strategic asset allocation. He operates within a management board that includes CEO Werner Gasser, founder Johannes Stegmaier, Wolfgang Rombach, and Vanessa Matheis. The group sets investment policy collectively, with individual transaction authority likely subject to the multi-signatory structure reflected in the firm's eleven registered Prokurists.

MSR's sourcing combines the personal networks of its founding families, its role on advisory boards such as Precisis GmbH's, and its position as a founding board member of VuFO, the association of independent family offices in Germany. The firm's dual noble-entrepreneur origin gives it access to industrial-family deal flow — most notably the Hymer family during the sale of Erwin Hymer Group — that a pure financial sponsor would struggle to replicate.

MSR is a multi-family office, advising roughly 50 high-net-worth families. Unlike a single-family office that manages one family's wealth, MSR pools advisory and investment resources across multiple clients. This structure gives it a broader capital base and a wider deal-sourcing network than a pure single-family office.

MSR uses a hybrid model: it makes direct co-investments and uses special purpose vehicles alongside commitments to private equity funds, hedge funds, and real estate vehicles. The firm targets buyout and co-investment opportunities, favouring control-oriented private equity but maintaining a diversified asset-allocation approach across asset classes.

Confirmed portfolio exposure includes digital health and healthcare services, shown by Thorben Katzer's board seat at Precisis GmbH, a medical device firm. MSR also lists climate technology and energy transition as focus areas. There is no public statement naming sectors the firm avoids, though its historic ties to the industrial and recreational-vehicle sectors through the Hymer family suggest comfort with manufacturing-adjacent investments.

The founding wealth is a blend of old European nobility — Count Hermann-Siegfried zu Münster-Meinhövel — and entrepreneurial capital from co-founder Johannes Stegmaier. MSR's client base includes the Hymer family, whose fortune originated from Erwin Hymer Group, the recreational-vehicle manufacturer. The firm's roughly 50 families are primarily German, with industrial and inherited wealth.

Philanthropic activities run through separate charitable vehicles, including MSR Social Impact gGmbH, the Erwin Hymer Stiftung, and the Paula Kubitscheck-Vogel-Stiftung. The firm also supports Zeppelin University, ProKA Oberschwaben, and the SEENEMA cinema cooperative in Bad Waldsee. These entities are legally distinct from the advisory and investment operations, preserving fiduciary separation.

MSR actively participates in direct co-investments and special purpose vehicles, often alongside corporate families or aligned GPs. Its representation of the Hymer family in the sale of Erwin Hymer Group demonstrates the firm's capability to lead complex transactions. The firm's network within VuFO and the Lerbach Competence Circle further expands its co-investor universe.
