What Dimo Diagnostic does

Dimo Diagnostic is a French real estate diagnostics company founded in 2016 and headquartered in Montpellier, providing the legally mandated suite of property inspections required before real estate sales or rentals in France. Its service portfolio spans 15+ diagnostic categories, including the Diagnostic de Performance Énergétique (DPE), audit énergétique, amiante, gaz, électricité, plomb (CREP), termites, Loi Carrez, Loi Boutin, ERP (État des Risques et Pollutions), état parasitaire, and diagnostic mérule. All work is performed by 100% in-house salaried diagnosticians certified by COFRAC-accredited bodies, with certifications valid for 5–7 years — a deliberate contrast to the subcontractor-heavy model common in the industry. Reports are issued after on-site intervention and payment, with the seller typically paying for sales diagnostics and landlords paying for rental diagnostics.

The company distributes through two distinct portals: a client portal (client.dimo-diagnostic.net) for individual property owners and a Pro portal (pro.dimo-diagnostic.net) targeting real estate agencies, property developers, and property managers. The go-to-market model combines a strong SEO-led local acquisition strategy — with city-specific landing pages for 13+ major French metros — direct phone-based quote conversion, content marketing via a French-language real estate blog, and earned media coverage in La Tribune, Le Figaro, Le Point, Challenges, 20 Minutes, and La Provence. Pricing is quote-based and not publicly disclosed, with the company claiming competitive positioning ("parmi les meilleurs prix du marché").

The business operates France-wide through a distributed network of salaried diagnosticians and reports cumulative scale of +200,000 diagnostics performed and +60,000 clients served, with a stated 96% customer satisfaction rate. Revenue is generated on a per-report basis with no subscription or recurring contract layer, making the company's financial profile directly tied to the volume of French residential real estate transactions. The company is privately held with no disclosed funding rounds, parent company, or institutional investors in the available source material, and currently employs 11–50 staff.
