CONVALOR Projektpartner GmbH

What CONVALOR Projektpartner GmbH does

CONVALOR Projektpartner GmbH is a Cologne-based, privately held German real estate equity partnership firm founded in 1974 by Erwin Walter Graebner. Operating as an independent Eigenkapitalgeber (equity partner), the firm provides equity capital, liquidity, and real estate development expertise to project developers across Germany, taking minority (and occasionally majority) stakes in project companies while allowing its development partners to retain operational control. Target project investment volumes start at EUR 10 million, with larger projects above EUR 100 million co-invested alongside additional equity partners.

The firm's portfolio spans residential developments (e.g., Heidekarree, Physikersiedlung, Waldviertel, Ringviertel in Cologne), commercial and office projects (Sky Eschborn, Vertikum Düsseldorf, Konrad-Adenauer-Ufer Köln, Q-West Gewerbequartier München), and an expanding Light Industrial / logistics book developed jointly with INBRIGHT (Holzpark Hanau, Brookkamp Hamburg, Businessparks in Nürnberg, Stuttgart, Solingen, and Friedberg). Over its 50-year history CONVALOR has participated in 190+ projects and currently deploys approximately EUR 50 million in invested equity capital.

CONVALOR earns returns through equity co-investment rather than fee-based revenue. Income is realized primarily upon project exit events — recent 2025 sales of the Bavaria Portfolio and Brookkamp to Swiss Life-funded vehicles illustrate the lump-sum return mechanics. The firm is led by Managing Directors Jan Hendrik Froesch (legal background, MD since 2008) and Dr. Oliver Bäumler (civil engineer, formerly of LANDMARKEN AG, MD since 2020), supported by a small team across project development, asset management, and controlling. It carries ICG compliance certification (audit standard PS 980) and was awarded the IHK Köln Ehrenurkunde for its 50th anniversary in 2024.

Direct peers

• BEOS AG: Germany's leading manager and project developer for commercial and light-industrial real estate. BEOS is both a long-standing JV partner of CONVALOR on multiple projects (Nürnberg, Dachau, Berlin, Garching) and a direct competitor for the same developer-led light-industrial mandates and institutional investor relationships.
• CILON GmbH: Mid-sized, owner-managed German project developer focused on value-based office-to-light-industrial investments. CILON co-developed the SKY Eschborn project with CONVALOR and operates the same minority-equity, partner-driven development model on similar asset classes.
• INBRIGHT: Berlin-based independent real estate developer and investor focused on light-industrial and office assets. INBRIGHT is CONVALOR's principal JV partner in light-industrial and competes for the same limited pool of mid-market German light-industrial equity co-investment opportunities.
• Bauwens Development GmbH & Co. KG: Owner-managed German real estate developer active at top German locations. Bauwens is both a CONVALOR JV partner (Waldviertel Köln-Rodenkirchen, Ringviertel Köln) and operates the same minority-equity, partner-driven development model on similar asset classes.
• Salik Holding: Second-generation family-run German project developer focused on terraced and apartment residential in Stuttgart/Baden-Württemberg with over EUR 100M completed volume. Listed as a CONVALOR partner and operates a comparable family-controlled, regional development model.

Broad incumbents

• Patrizia SE: European real estate investment manager with significant German CRE equity, investment, and asset management capabilities. Operates broadly across German residential, commercial, and value-add strategies and competes for institutional equity co-investment mandates of the type CONVALOR accesses.
• Art-Invest Real Estate: Cologne-headquartered German real estate investment and project development manager. Art-Invest is a comparable German equity-led platform operating across office, hotel, residential, and mixed-use developments and competes with CONVALOR for developer relationships in the Rhine-Ruhr region.
• Instone Real Estate Group: Frankfurt-listed German residential and quarter developer (formerly part of Deutsche Wohnen). Comparable in residential quarter co-investment activity (e.g., CONVALOR's Waldviertel, Ringviertel, Heidekarree projects) at a larger, publicly-traded scale.
• Deutsche Investment Holding GmbH: Berlin-based German real estate investment manager operating across residential, commercial, and value-add strategies with multiple vehicles. Comparable as a broader German equity-led real estate platform that institutionalizes the kind of co-investment model CONVALOR runs as a private firm.
• OFB Projektentwicklung: Frankfurt-based German project developer with broad activity across residential, commercial, and public-sector real estate. OFB competes for the same German development equity partnerships and end-buyer institutional demand as CONVALOR.
