DEFIM

What DEFIM does

DEFIM (legal entity: DEFIM Expertises SAS) is a French franchise network specializing in mandatory and voluntary real estate diagnostics for property sales, rentals, and renovation projects. Operating 51 independently franchised agencies across France under the EXIM group umbrella, DEFIM delivers the full spectrum of legally required inspections — including DPE (energy performance), amiante (asbestos), plomb (lead), termites, gaz, électricité, Carrez/Boutin mesurages, and état des risques — alongside specialized services such as DTG, DTA, Audit Énergétique, Bilan 360 / DPE Projeté, DPE Tertiaire, mise en copropriété, and pre-demolition asbestos and HAP surveys. Technology inputs include latest-generation X-ray fluorescence (XRF) analyzers for lead detection and ADEME/Ministry-validated software applying the 3CL method for DPE calculations; DEFIM also publishes a DPE reform 2026 simulator on its website to capture regulatory-driven demand.

DEFIM operates a dual revenue model. At the franchisor level (DEFIM SAS, 11–50 employees), revenue is generated through recurring franchise fees, royalties, and centralized services (marketing, technical support, purchasing power, legal and commercial coaching). At the network level, franchisees charge property owners and real estate professionals one-time transactional fees for inspection work. Pricing is quote-based and not publicly disclosed; customers reach the network via the website quote form, phone, and direct contact with local franchisees. The customer base is structurally diversified across individual property owners (sellers, landlords, buyers) and SMB real estate professionals (agencies, notaries, property managers, municipalities), with no named enterprise anchor customers.

The network is governed by a parent conglomerate (EXIM) that also owns Ex'im, Minerva, and Infodiag; DEFIM maintains membership in the Fédération Alliance du diagnostic immobilier for industry advocacy. Leadership comprises Christine Boutry as Directrice Nationale and Julien Coupe as Responsable éditorial. The company has positioned itself to benefit from the 2026 French DPE regulatory reform, which is expected to drive increased diagnostic and energy audit demand across an estimated 850,000 dwellings exiting the 'passoire thermique' category.

Revenue model

1. Diagnostic inspection fees: DEFIM franchised cabinets charge property owners for mandatory real estate diagnostic inspections required for property sales and rentals. Fees are quoted per inspection or bundled per property, typically varying by property size and diagnostics required. Revenue is generated through one-time transactional service fees paid by individual clients (homeowners, landlords, real estate professionals) and is not subscription-based.
2. Franchise fees and network services: DEFIM generates revenue as franchisor through fees charged to franchisees, including initial franchise fees, ongoing royalties, and access to shared services (centralized marketing, technical support, purchasing power through network partnerships, legal and commercial coaching).
