What Ortec Group does

Ortec Group is a France-headquartered (Aix-en-Provence) privately held industrial services integrator, organized as Ortec Services GIE, employing 12,500+ people across 28 countries through 300+ agency locations. Founded circa 1995, the group operates three integrated pillars — Design (engineering, calculation, modeling, project management support, digital and data services, maintenance engineering), Build (EPCI large projects, mechanical and metalworking, construction, revamping, nuclear maintenance, electrical and thermal engineering), and Preserve (industrial maintenance, industrial cleaning, depollution and site rehabilitation, waste management, sanitation, tertiary building services, industrial oil logistics).

The company serves enterprise clients in regulated, safety-critical end markets — nuclear, defense, aeronautics/aerospace, oil & gas, life sciences, heavy industries, and transport — plus public-sector waste and remediation work. Select named customers include TotalEnergies (oil & gas, with two HSE/Safety Awards at the Le Havre site), Sweetch Energy (regulatory studies for osmotic power), SYMBIO, Plastic Omnium, and Stellantis (hydrogen fuel cell and battery reliability studies), and the French Ministry of Ecological Transition via the TrackDéchets traceability platform. Ortec also develops proprietary tools: GEODE waste-management software (integrated with TrackDéchets), the I-CO2 carbon-footprint calculator for construction sites, the NT4 robotized descaler for nuclear maintenance, and a Dantech-led applied-innovation portfolio (Eolbox, Gaia, Smart-li, Oreve EV charging).

Revenue is generated via project-based, quote-driven B2B enterprise contracts across professional services (engineering, design, construction, environmental) and managed services (industrial maintenance, delegated facility management, waste treatment). Multi-year contracts dominate, with the go-to-motion relying on direct enterprise field sales, a 300+ agency footprint for local presence, and web-based project inquiry forms. The group has grown both organically and through roll-up M&A (six disclosed acquisitions between 2013 and 2021, including Sonovision, Brunet Group, and Soleo Services).
