What G.A.O • Groupement d'Artisans de l'Ouest does

G.A.O • Groupement d'Artisans de l'Ouest is a French general building contractor (entreprise générale de bâtiment) structured as a SARL and incorporated in 2024 under RCS Nantes (889 522 173), with operational presence in Vertou and a registered office in Les Sorinières. The company aggregates multiple specialized artisans under a single point of contact to deliver residential renovation services across five western France departments: Loire-Atlantique (44), Maine-et-Loire (49), Vendée (85), Morbihan (56), and Ille-et-Vilaine (35). Its service portfolio is organized around four core pillars — Couverture (roofing), Isolation (insulation), Murs & Façades (walls and facades), and Chauffage (heating with wood and pellet stoves) — augmented by electrical, ventilation, solar panel installation, and wood/framework treatment services.

The underlying technology is conventional construction and renovation craft rather than any software platform. The heating pillar rests on resale and installation of branded wood-burning stoves (Arès, Hermes) and pellet stoves (Gaïa, Freya, Fuji-Front, Oya) sourced from manufacturers such as Jolly-Mec, Godin, and Artense, with efficiency ratings of 91–95% for the pellet line. The company holds RGE Qualibat and Qualibois certifications, which qualify customer projects for French state energy-renovation subsidies and is the primary regulatory enabler of its demand funnel. Its digital footprint is a WordPress website with service pages, a project portfolio, and an online cost simulator (Simulation Travaux), supported by Google Maps, Facebook, and Instagram profiles.

Commercially, G.A.O operates a sales-led, quote-based B2C model targeting residential homeowners seeking to improve energy performance, roofing condition, and facade integrity. Revenue is generated per project with free estimates (devis gratuit) as the primary lead-conversion mechanism; pricing is custom to each scope of work and is not publicly disclosed. The company is bootstrapped with a €1,000 share capital, owner-directed by Alexandre ALLORY, and operates with approximately 12 employees. There are no disclosed funding rounds, institutional investors, or parent/subsidiary structures.
