Franz Martz & Söhne Private Treuhand
Founded in 2011, Franz Martz & Söhne Private Treuhand operates as a wholly owned subsidiary of framas Kunststofftechnik GmbH, the plastics-technology group that supplies components to major athletic footwear brands including Nike, Reebok, Under Armour, and New Balance. The firm manages capital generated by this industrial legacy alongside assets for more than 250 external client families, blending single-family-office DNA with an MFO mandate. The firm deploys across a fund-of-funds architecture supplemented by direct portfolio construction. Confirmed investment types include fund commitments and philanthropic or mission-related allocations, with a disclosed emphasis on industrial technology, advanced materials, and circular-economy exposures. Geographic concentration spans Europe and North America. The firm states it has over €200M in fund mandates and manages over €500M in total client assets, with portfolios that Morningstar has rated four and five stars in prior periods. Every advisor on the team claims at least 25 years of financial-market experience. The firm maintains membership in the Verband unabhängiger Vermögensverwalter Deutschland (VuV) and participates in its arbitration process. In 2023 it was recognized in the WIN-Journal of the regional Wirtschaftsnetzwerk Saarland network, reflecting embedded ties to the Saar-Lor-Lux business community. Since August 2018 the firm has sponsored SV Elversberg, the local football club, and is visible at Ursapharm-Arena. The defining structural feature is the combination of a multi-family-office client business with full ownership by an active industrial operating company, framas Kunststofftechnik. That architecture links the firm's wealth-management clients to a still-operating manufacturing enterprise, which creates a materially different governance and capital-preservation framework than a standalone MFO. The Dassler family connection — Franz Martz's daughter married Adi Dassler — adds a multigenerational credibility layer unique among German family offices.

Frequently asked questions
How does Franz Martz & Söhne source its clients?
The firm draws heavily on the regional Saar-Lor-Lux network, along with the industrial relationships of its parent, framas Kunststofftechnik. Its membership in the Wirtschaftsnetzwerk Saarland and sponsorship of local club SV Elversberg reinforce a community-based sourcing model. More than 250 client families have been onboarded since 2011, according to the firm's website.
What is the relationship between the firm and the Adidas founding family?
The connection is marital. Franz Martz, the founder of the framas group, had a daughter who married Adi Dassler, the founder of Adidas. While the multi-family office does not manage the Dassler fortune directly, the family tie adds multigenerational industrial credibility and informs the firm's long-term, capital-preservation orientation.
Is Franz Martz & Söhne a single-family office or does it serve external clients?
It is a multi-family office serving over 250 external client families. However, it is 100% owned by framas Kunststofftechnik GmbH, the Martz family's industrial operating company. This creates a hybrid structure where the MFO sits inside a single-family holding company, managing both family-derived and outside capital.
What entity provides the underlying wealth managed by the firm?
The industrial operating company framas Kunststofftechnik GmbH is the ultimate source. Framas supplies plastic components to global athletic footwear brands — confirmed relationships include Nike, New Balance, Reebok, and Under Armour. The MFO operates as a wholly owned subsidiary of that company.
Does the firm invest directly or through funds?
It operates primarily as a fund-of-funds manager with over €200M in fund mandates. It also constructs custom portfolios for individual client mandates, with stated sector focuses in industrial technology, advanced materials, and the circular economy. There is no public evidence of direct co-investment or direct-deal capability.
How are the firm's own funds rated?
Morningstar has rated the firm's funds four and five stars in prior evaluations, according to its website. The firm highlights this as an external validation of its active risk management and portfolio-construction discipline. No specific fund names or current ratings are disclosed publicly.
What governance or oversight structure applies to the firm?
The firm is a member of the Verband unabhängiger Vermögensverwalter Deutschland (VuV), the association of independent asset managers in Germany, and participates in its ombudsman arbitration process. This provides an external mechanism for client disputes, complementing internal governance under the parent company's ownership structure.
