Gemeinnütziger Spar- und Bauverein Friemersheim eG

What Gemeinnütziger Spar- und Bauverein Friemersheim eG does

Gemeinnütziger Spar- und Bauverein Friemersheim eG is a registered German housing cooperative (eingetragene Genossenschaft / eG), founded on May 18, 1919 and headquartered at Kaiserstraße 53 in Duisburg-Friemersheim. The cooperative manages approximately 1,350 residential apartments — supplemented by commercial units, parking spaces, and garages — across four left-Rhine southwestern districts of Duisburg (Friemersheim, Rheinhausen, Bergheim, Rumeln-Kaldenhausen), serving roughly 2,500 members who hold at least one €600 business share plus a €40 joining fee and receive a 4% annual dividend.

The technology stack is operational rather than product-oriented: a CRM-based MeinBauverein customer portal (web and iOS/Android app) on Aareon integrates with Techem for real-time consumption data and supports digital contract management, service requests, and push notifications; property listings are distributed through ImmobilienScout24 and the wohnungshelden GmbH application service; cable infrastructure is provided via Vodafone Kabelnetz; and a new ERP system was deployed in 2025 to process heating and operating cost invoicing.

The business model is non-profit cooperative housing: recurring rental income on approximately 1,350 units is the primary revenue stream, supplemented by commercial and parking income. Distribution is fully direct — apartment seekers apply via the cooperative's own website, wohnungshelden, or ImmobilienScout24, with onboarding handled in-house. Governance is democratic: a Vorstand (Hendrik Brendgen, Sebastian Petereit) runs operations; an Aufsichtsrat chaired by Jörg-Wilhelm Höffken provides oversight; and a 65-member Vertreterversammlung elected across 6 districts sets strategic direction every 5 years. The cooperative is affiliated with the Duisburger Wohnungsgenossenschaften consortium ('Ein sicherer Hafen'), VdW Rheinland-Westfalen, and GdW Bundesverband.
