4 Friends Investment
4 Friends Investment GmbH was founded by Stefan Zimmermann and Matthias Schmitz, two former ACREST Property Group executives who brought operational real estate experience into the multi-family office structure. The firm operates out of Frankfurt am Main, managing capital for a group of families and associated investors with a mandate centered on long-term value creation. Christoph Wöstefeld serves as CEO, while Friedrich Lammers leads transaction execution. The portfolio spans direct real estate holdings, private equity, distressed and turnaround situations, and a dedicated crypto investment vehicle called TRUBICON. Real estate exposure includes the 4FI Berlin Mitte mixed-use development, the 4FI Berlin Properties residential portfolio, the 4FI European Properties commercial portfolio, the 4FI Poland Portfolio of mixed-use assets, and the FDB GmbH Property Portfolio in Germany. On the operating side, the firm owns TRU Fitness, a German fitness chain that anchors the Sports & Wellness sector allocation. The private equity book includes direct co-investments and SPVs across Europe. 4 Friends Investment maintains an active membership in the GRI Club, a professional network focused on real estate and infrastructure, which provides a sourcing channel for off-market European property transactions. The firm also operates the TRUBICON Crypto Investment vehicle, signaling a willingness to allocate into digital assets alongside traditional real assets. The Poland portfolio and pan-European commercial holdings indicate a geographic footprint that extends well beyond the German domestic market. What distinguishes 4 Friends Investment structurally is the combination of an operating business — TRU Fitness — held alongside a discretionary multi-asset portfolio within a single multi-family office vehicle. Most German multi-family offices remain strictly allocative; 4 Friends Investment blurs the line between asset manager and holding company, running a fitness chain as a controlled subsidiary while simultaneously managing direct real estate, private equity co-investments, and a crypto fund on behalf of its families.
