Solvia Vermögensverwaltungs

Solvia Vermögensverwaltungs manages the capital of the Mast family, owners of Mast-Jägermeister SE, the iconic German herbal liqueur brand founded in 1934 in Wolfenbüttel. The family office, formerly known as Phoenix Beteiligungs- und Vermögensverwaltungsgesellschaft mbH until a name change in 2006, was established to separate the operating business — now overseen by family member Florian Rehm as supervisory board chairman — from the investment portfolio. The office serves the family's fifth and sixth generations, maintaining the tight geographic and cultural ties to Lower Saxony that define its posture. The office deploys capital across a diversified mix that includes direct private equity, private credit, real estate, infrastructure, and fund commitments. Schäfermann, who joined with a background at Deutsche Beteiligungs AG, represents the shift toward professionalized direct investing — a track most visible in Solvia's stake in Pegasus CP Holding, where former managing director Ralf Bauderer chairs the advisory board. The renewable-energy book spans wind, photovoltaic, and rooftop solar installations on agricultural properties, while organic farmland holdings embed the family's thesis in carbon and environmental assets. Confirmed geographies include Germany and the United States, with New York City mixed-use real estate rounding out the hard-asset base. The office's leadership transition is unusually legible for a private German family vehicle. February 2025 marked the formal appointment of Wolf-Jakob Herpich — recruited from the Hasso Plattner Foundation and the Haub family legacy — as managing director alongside Jarno Schäfermann, while Bauderer moved to an advisory board role after roughly two decades at the helm. Authorized signatories Dirk Martin Meier and Dr. Ulli Wagner, both appointed in November 2021, round out the governance layer. Philanthropic activities flow through the Curt Mast Foundation, the eva foundation for ecosystem value, and Tomvia gGmbH, reflecting a formal separation between investment and mission-driven capital. Solvia's structural differentiator is the twin-engine approach: a permanent-hold hard-asset base — farmland, commercial real estate — that anchors the balance sheet, paired with a growing direct-investment capability that operates more like a deal-by-deal principal shop than a conventional multi-generational allocator. The dual managing director model, combining a Deutsche Beteiligungs veteran with a foundation-trained principal, creates a governance architecture designed for continuity rather than founder dependency. It is a deliberate departure from the single-CIO model common among mid-sized European family offices.

Frequently asked questions

Who runs investment decisions at Solvia?

Managing directors Jarno Schäfermann and Wolf-Jakob Herpich lead the office as of February 2025. Schäfermann, a Deutsche Beteiligungs AG alumnus, has been managing director since at least 2019. Herpich was recruited from the Hasso Plattner Foundation and previously worked with the Haub family office. Former managing director Ralf Bauderer, who ran Solvia for roughly two decades, moved to an advisory board chairman role in 2025.

Where does the underlying wealth come from?

The Mast family owns Mast-Jägermeister SE, the producer of the Jägermeister herbal liqueur brand, founded in Wolfenbüttel in 1934. Florian Rehm, a major shareholder, chairs the company's supervisory board. The family office serves the fifth and sixth generations, with its headquarters remaining in Wolfenbüttel.

What is Solvia's known posture on direct versus fund investments?

Solvia operates on both tracks. The office makes direct co-investments and stakes — most visibly in Pegasus CP Holding, where former MD Ralf Bauderer chairs the advisory board — alongside fund-of-fund commitments. The hard-asset portfolio, including German organic farmland and New York real estate, is held directly. The capital structure does not rely on outside LPs, keeping all deployment tied to family capital.

Which sectors does Solvia explicitly avoid?

The office does not tag exclusionary sectors publicly. The confirmed focus areas — ClimateTech, Energy Transition, AgriTech, PropTech, and Supply Chain — suggest an orientation toward real-asset-backed and sustainability-adjacent themes rather than consumer internet or pure-play software. The investment-stage range spans seed through buyout, but observable deployments concentrate on tangible asset classes.

Does Solvia maintain philanthropic structures, and how are they separated?

Three entities carry the family's philanthropic capital: the Curt Mast Foundation, the eva foundation which focuses on ecosystem value, and Tomvia gGmbH. These are legally distinct from the investment office, preserving the separation between Solvia's return-seeking portfolio and its mission-driven allocations.

How is Solvia related to the Haub family and Hasso Plattner Foundation?

Solvia is not structurally linked to either. The connection is through Wolf-Jakob Herpich, appointed managing director in 2025, who previously held roles at the Plattner Foundation and within the Haub family office ecosystem. His recruitment signals Solvia's effort to import institutional-scale governance practices from other prominent German family offices.

What is Solvia's renewable energy exposure?

The renewable-energy book includes wind assets, photovoltaic installations, and rooftop solar systems on agricultural properties, concentrated in Europe. These sit alongside organic land holdings and carbon-environmental asset positions, forming an integrated real-asset strategy that links energy transition with the family's broader agricultural footprint (per public record).
