Groupe National Immobilier

What Groupe National Immobilier does

Groupe National Immobilier (GNI) is a French participative groupement founded in 2007 by the Delchambre family and operated through SARL GNIMMO, headquartered in Verquières (453 Route Nationale 7). It serves independent real estate agencies that want collective purchasing power and shared digital tools without ceding brand identity or paying the 5–8% turnover commissions typical of franchise networks. The platform currently spans 427+ partner agencies, 1,400+ advisors, and 49 French departments, with member governance codified since 2024 through the SIPA (Société d'Investissement Participatif des Agences), a 100% agency-owned investment vehicle that votes on technology priorities in two annual general assemblies.

The technology stack is built around GNI Connect, a mobile and web application for real-time mandate sharing, buyer-lead notifications, and inter-agency messaging, backed by integrations with at least eight transaction CRMs (AC3, Apimo, Modelo, Immo-Facile, Logic-Immo, Hektor, Netty, Ubiflow) and the Jinka aggregator. Listings flow from a single entry point to 8+ national and regional portals (SeLoger, BienIci, Logic-Immo, Figaro Immo, A Vendre A Louer, ParuVendu) at negotiated volume rates. Ancillary services include the Guide National Immobilier and gnimmo.com portals (9,800+ listings from ~470 agencies), the GNI Store for commercial printing, the immo² training platform for Loi Alur certification and an AI-adoption community (GPT Club), and a shared "CRM groupement" rebuilt and rolled out in April 2026.

The business model is a fixed annual membership fee ("cotisation annuelle fixe") with à-la-carte selection of services and no commission on member-agency revenue, contrasted explicitly against traditional franchises. Revenue streams combine recurring subscription income, one-time commercial printing orders, and training/formation fees at preferential rates, while SIPA finances member-voted technology investments. GTM is consultant-led inside sales supported by community referrals, annual conventions, regional events, and public-facing portals that double as member service and lead-generation assets. The company remains privately held, with Dorian Delchambre as founder and director.
