Ring Deutscher Makler

What Ring Deutscher Makler does

Ring Deutscher Makler – Landesverband Berlin und Brandenburg e. V. (RDM) is a registered non-profit professional association (eingetragener Verein) representing real estate agents and property managers in the German states of Berlin and Brandenburg. The association operates as a regional state chapter (Landesverband) and delivers a bundled portfolio of membership services: the RDM-Fachkundesiegel professional certification, the twice-yearly RDM-Immobilienpreisspiegel price guide, the RDM-Expertensuche online directory, online and in-person training seminars (covering rental law, property management, and regulatory compliance, with MaBV continuing education credit), periodic RDM Kompakt newsletter, and an exclusive member portal. Annual flagship events include the Immobilientag conference and Neujahrsempfang reception, which regularly attract senior Berlin politicians and industry leaders.

RDM is governed by a board led by Chairman Markus Gruhn, with operational management handled by Managing Director Axel Lipinski-Mießner. The association is financed primarily through member dues (undisclosed) and seminar/training fees (EUR 120 for members, EUR 220 for non-members per seminar). Its technology stack is modest: a WordPress website with member authentication, an external price database operated via immobilienpreise-berlin.de, and Zoom-delivered seminars. There are no proprietary software products, no AI/ML capabilities, and no venture capital or external ownership. Its competitive positioning rests on long-standing regional brand recognition, regulatory advocacy, and the cumulative value of its bundled content and certification assets.

The customer base consists of licensed real estate brokers (Immobilienmakler) and property managers (Hausverwalter) operating in Berlin and Brandenburg, with a secondary consumer-facing touchpoint via the Expertensuche directory. The organization maintains minor commercial partnerships with VARM, Finioo, Schnoor Immobilien, and Markus Gruhn Immobilien, and does not pursue geographic expansion beyond its two-state remit.

Scale indicators1 record

Recent moves6 records

Expansion highlights3 records

Broad incumbents

• Engel & Völkers: Large Hamburg-headquartered international real estate brokerage franchise with strong Berlin presence — operates in the same real estate professional services category as RDM's members but as a brokerage rather than an association.
• Von Poll Immobilien: Germany-based premium residential and commercial real estate brokerage franchise — comparable to RDM's agent constituency in service offering and Berlin market presence, but as a competing commercial operator.

Direct peers

• Haus & Grund Deutschland: Germany's largest property owner and landlord association, providing member education, legal advice, and political advocacy — highly comparable membership-association model even though its core constituency (owners) differs from RDM's (agents/managers).
• Immobilienverband Deutschland (IVD): Germany's national professional association for real estate agents, brokers, and property managers — directly comparable in mission, member services, training, and advocacy focus to RDM, but with national scope rather than Berlin-Brandenburg only.
• ZIA Zentraler Immobilien Ausschuss: German real estate industry's umbrella lobbying organization representing the full real estate value chain — comparable in advocacy/policy focus to RDM but operating at national rather than regional level.
• BFW Bundesverband Freier Immobilien- und Wohnungsunternehmen: National trade association for German real estate companies and project developers, offering similar member training, certification, and industry advocacy — directly comparable in structure to RDM.
