SASI

What SASI does

SASI is a French multitechnical industrial services company headquartered in Alsace (operational base in Haguenau; registered office in Gambsheim), founded in the early 1970s and operating as a SARL with €840,000 in share capital. The company delivers integrated industrial services across five core disciplines: industrial electricity (electrical engineering, HT/BT distribution, cabinet building, compliance), industrial automation (PLC programming, SCADA/IHM, industrial networks, special machines, custom industrial software), industrial mechanics (machining, welding, mechanical maintenance, industrial relocation), industrial instrumentation (sensor verification, transmitter calibration, valve positioner configuration with COFRAC-traceable metrology), and industrial valves (regulation valve calibration, safety valve testing, pump overhaul). A multitechnical engineering office (bureau d'études) coordinates concept-to-commissioning project delivery, supported by in-house workshops for machining, welding, electrical cabinet wiring, and valve/pump overhaul with dedicated test benches rated up to 600 bar hydraulic / 190 bar nitrogen. SASI is part of the SERINDUS Groupe (since 2003), which federates complementary industrial service companies across France and Germany, with ERAT as its German sister entity.

SASI's customer base is concentrated in process-intensive industrial verticals — chemical/petrochemical, pharmaceutical, agri-food/brewing, automotive/aeronautics, and paper — operating primarily in the Grand Est region of France and Baden-Württemberg in Germany, with industrial relocation services extended nationwide across France. The company is certified MASE (industrial safety), ISO 9001 (quality management), and ATEX (explosive atmospheres), enabling it to operate on hazardous and high-risk industrial sites. Business model is project- and contract-based professional services sold through direct field engagement by charged d'affaires and technical teams; services are quoted per project, billed on a pay-as-you-go cadence, with no public pricing. Revenue streams include contractual and emergency maintenance, new installation/construction, valve/pump/safety-valve overhaul, structural steel fabrication, and build-to-order special machines and test benches. Industrial software and IIoT offerings (custom PC and embedded development, ERP/MES integration) represent an emerging capability area, though AI/ML is not explicitly disclosed.

Broad incumbent overlapping SASI's industrial-services niche within a much wider portfolio.
• VINCI Energies: VINCI Energies is a global network of multitechnical services brands (including Actemium, Omexom, Infrateam) serving industry, infrastructure, and energy markets. Broad incumbent competitor; competes for the same large industrial maintenance and modernization contracts SASI targets, but at a much larger scale and brand recognition.
• ENGIE Solutions (Endel): ENGIE Solutions is the ENGIE group's B2B services arm covering industrial maintenance, electrical engineering, instrumentation, and energy-efficiency retrofits. Broad incumbent that competes with SASI for industrial-maintenance and modernization tenders, especially in chemical and energy verticals.
