What atos groupe sogei does

ATOS Groupe SOGEI is a privately held French industrial engineering and manufacturing firm headquartered in Bagnols-sur-Cèze (Gard), operating from a single site in the Z.I. de Berret industrial zone. The company was formed in 2014 from the merger of founder Jean-Maurice PONGY's SOGEI Ingénierie (founded 1989) and ATOS Industrie (founded 2005), consolidating engineering studies and industrial realization capabilities under one structure. It operates six interconnected service poles: (1) Engineering Studies for general factory installation; (2) Special Mechanical Machines for custom industrial equipment; (3) Industrial Metalwork in steel, stainless steel, and aluminum; (4) Electro-Hydraulic Handling equipment, including a proprietary nucleariable gripper range developed in-house for dismantling applications; (5) HVAC / Climate Engineering; and (6) multi-trade Building Maintenance contracts. Underlying technology comprises AutoCAD, SolidWorks, Melody, TopSolid, Climawin, and See Electrical for design and calculation, and a FARO Focus S 150+ laser scanner for millimetric 3D site surveys acquired in 2020.

The company serves nuclear operators (AREVA, CEA), chemical and pharmaceutical clients (Sanofi), steel, food processing, and tertiary/municipal customers (Hôtel de Ville installations), operating in both conventional and non-conventional (hazardous, nucleariable) environments. The business model is project-based professional services plus custom equipment manufacturing: contracts are scoped per engagement with quote-based pricing, distributed through direct sales to industrial and institutional buyers. Multi-trade maintenance is offered under patrimoine contracts providing a recurring revenue layer on top of project work. The firm holds MASE (since 2011), CEFRI (since 2015), ISO 9001, and Qualibat certifications, and maintains nuclear security habilitations (PR1CC, GIES, Confidentiel Défense), making regulatory credentials a core operating asset.

ATOS Groupe SOGEI is a tightly held company owned and managed by Jean-Maurice PONGY, with a stated headcount of 1–10 employees and no evidence of external institutional investment or public listing. It operates exclusively in France, relies on its corporate website as the primary commercial channel, and has no disclosed social media presence. Strategic emphasis is on integrated turnkey delivery (study-to-installation by a single entity), specialization in hostile-environment work, and internal R&D into custom nuclearizable tooling — most notably the proprietary electro-hydraulic gripper line. Revenue is not publicly disclosed.
