What Oiso.fr (observatoire Immobilier Du Sud Ouest) does

OISO (Observatoire Immobilier du Sud-Ouest) is a French non-profit association (loi 1901, SIREN 522 800 408) founded in 2009 and headquartered at 51 Quai Lawton, Bordeaux. It operates as an associative observatory dedicated exclusively to the new-build real estate market in the Nouvelle-Aquitaine region, serving real estate professionals including property developers (promoteurs), social landlords (bailleurs sociaux), urban developers (aménageurs), banks, study offices, urban planning agencies (A'Urba, Audap), and territorial authorities (Bordeaux Métropole, CA de la Rochelle, MACS, CA Pays Basque et Pau Béarn, DDTM33, Département 33). The organization is governed by President Christophe Duportal with day-to-day operations led by General Delegate Orianne Esvan, supported by a small staff of under 10.

The core technology is an online data platform providing member-restricted access to an interrogable database with aggregated data by commune, departmental dashboards, building permit data, socio-economic indicators, interactive cartography of current and historical development programs, and customizable PDF exports. The platform's data is sourced through quarterly operator surveys directly collected from industry players — a methodology not replicated by commercial data providers — and is governed by RGPD-compliant privacy practices.

OISO generates revenue exclusively through annual membership subscriptions across three tiers (Membre actif for data contributors, Membre partenaire for non-contributing banks and study offices, and Membre partenaire abonné for macro-level subscribers), with pricing varying by geographic sector and member category and not publicly disclosed. Go-to-market is community-led and event-driven, combining direct outreach, annual economic conferences, and thematic roundtables held in Bordeaux, La Rochelle, and Anglet. The association is also part of a national network of regional housing observatories (OREAL, OCELOR, OLOMA, OLONN, Observer, Capem) that share data standards and methodologies across French regions.
