STIA

What STIA does

STIA (Services de Technologies Industrielles Atlantique) is a privately held French industrial-services company founded in 2012 by William Wafo, François Griveau, and Hervé Quérard. Headquartered in Sainte-Luce-sur-Loire near Nantes with a second site in Aizenay (Vendée), STIA operates as an industrial ensemblier providing three interconnected core services: industrial maintenance (mechanical, electromechanical, electrical, boiler-making, and piping repairs aimed at production-tool uptime), industrial transfer and assembly (study through commissioning of complex equipment relocation and reinstallation), and industrial piping (design, prefabrication, and on-site installation of fluid and gas networks including modules and skids). Underlying technical capability rests on qualified welding procedures (QMOS/DMOS, QS certifications across TIG, MIG/MAG, covered-electrode processes on stainless and carbon steel), POLYSOUDE orbital welding for hygienic applications, endoscope-based internal pipe inspection, and compliance with CODETI, DESP 97/23 CE, NF EN 13480, NF EN 10088, and ASME BPE standards.

The company generates revenue through project-based professional-services engagements with enterprise industrial clients across food and beverage, pharmaceutical and cosmetic, energy, aerospace, and general manufacturing verticals. Documented customers include Air Liquide, Safran, Biscuiterie Saint-Michel, LU (Lefèvre-Utile), Lydall, Christeyns, NGK Berylco, Alisma Filtration, Galliance, Rector, Solina, Chicago Pneumatic, and ArcelorMittal; notable project signals include 1,400 meters of 316L stainless-steel special-gas piping installed for Safran in five weeks and a 12+ year helium-transfer partnership. Pricing is bespoke per project scope and duration, with multi-year maintenance contracts; no standardized public pricing exists. Go-to-market is exclusively direct field sales via mobile technical teams dispatched from the two Pays de la Loire offices, with daily service in Loire-Atlantique and Bretagne and nationwide deployment for specialized projects.

STIA operates at human scale (~60 employees, including ~40 technicians) and reports a €9M revenue figure as of 2024/2025 for the STIA Vendée scope. Beyond services, STIA runs STIA Académie, an internal training pipeline partnering with La Joliverie, UIMM Fab'Academy, and AFPA to develop welders, boiler-makers, and maintenance technicians — currently hosting its 7th apprenticeship promotion at ~12% of headcount. The company is pursuing MASE safety certification and maintains a regional brand presence through welding championships, the HBC Nantes partnership, and local employment forums. Ownership is concentrated among the three founders; no institutional investors or parent-company structure have been disclosed.

Core offering

STIA is an industrial ensemblier providing multitechnical services to industrial clients: (1) industrial maintenance covering mechanical, electromechanical, electrical, boiler-making and piping repairs to optimize production line performance; (2) industrial transfer and assembly, encompassing engineering, technical operations management, and reinstallation of complex industrial equipment; and (3) industrial piping — design, prefabrication, and on-site assembly of piping networks, modules and skids for fluid and gas transfer applications. Services are delivered by pluritechnical teams from offices in Nantes and Vendée, primarily across the Grand Ouest region.

Product overview

STIA operates as an industrial ensemblier (general contractor) offering three interconnected core services: industrial maintenance (maintenance industrielle), industrial transfer and assembly (transfert & montage industriel), and industrial piping (tuyauterie industrielle). These complementary services are delivered through a pluritechnical team and enable STIA to provide turnkey solutions to industrial clients. The company also operates STIA Académie for training and workforce development, and offers custom skid/module fabrication as a specialized sub-product. Safety services and MASE certification preparation support operational excellence.
