CREHA OUEST

What CREHA OUEST does

CREHA OUEST is a French non-profit association (loi 1901), founded in 1998/1999 and headquartered in Saint-Herblain (Pays de la Loire), that serves as the designated manager and animator of the departmental social housing demand information system across nine departments in the Bretagne and Pays de la Loire regions. The organization operates on a membership-funded model, with approximately 950 partner organizations — including social landlords (bailleurs sociaux), local authorities (collectivités territoriales), the French State (DREAL services), Action Logement Services, and ADIL agencies — representing over 4,000 active users. Governed by a Board of Directors drawn from its membership, CREHA OUEST coordinates shared digital infrastructure, training, and statistical services for the social housing sector in western France.

The organization's core technology is the IMHOWEB platform, a solution provided by Groupe SIGMA that manages social housing demand files, offer management, demand-supply matching, instruction processing, and reporting. In March 2026, CREHA OUEST completed a three-year project to merge nine separate departmental databases into a single interregional database containing 354,000 housing requests, 4,000,000 digitized documents, 435,000 housing units, 518,000 instruction phases, and 31,000,000 events. Complementing IMHOWEB, the Observatoire Augmenté provides statistical and cartographic observation with monthly data updates from FDLS, RPLS, OPS, and INSEE sources. A multilingual AI-powered chatbot, developed in partnership with monLogement.ai and hosted in France, supports 25 languages across demandelogement.fr sites. The API DRM enables retrieval of monthly resource data from CAF and MSA for housing demand management.

CREHA OUEST generates revenue through three streams: recurring membership fees from partner organizations (with collectivité tier access to Observatoire Augmenté at approximately €700 per year); professional training services on IMHOWEB and statistical tools, offered in both open-enrollment (INTER) and customized on-site (INTRA) formats at €60–€420 per session; and ad-hoc data processing services (lists, extractions, special treatments) that exceeded 200 solicitations in 2020. Distribution is direct via the IMHOWEB platform, the Observatoire Augmenté portal, a Freshdesk-powered support system, and a dedicated training portal, all gated by individual authentication for member organizations.
