What SNEF Group does

SNEF Group is a privately held French multi-disciplinary engineering, systems integration, and maintenance group headquartered in Marseille and operating since 1905. Through its core Snef brand and a portfolio of specialty sub-brands — Snef Connect (digital networks, hypervision, cybersecurity), Snef Clim (HVAC and climate engineering), Snef Audiovisuel (audiovisual systems integration), Snef Power Services (nuclear sector), and Snef Maintenance (24/7 multi-technical maintenance) — the group delivers high- and low-voltage electrical engineering, industrial automation, energy optimization, security systems, climate engineering, audiovisual integration, and facility maintenance. It also owns acquired specialty brands including Ekium, Fouré Lagadec, WATT, visiativ, iQanto, ABGi, and Protea, extending capabilities into engineering, energy, digital transformation, and ESG consulting.

The group's 8,800 contributors operate from 80 branches across France and 14 international locations, with a 100% in-house manufacturing capability for electrical cabinets including seismic and nuclear-grade specifications. Its technology stack spans power distribution and substations, ATEX-zone industrial electrical engineering, SCADA and instrumentation, building management systems, electronic security and hypervision, and renewable energy EPC (photovoltaic, hydroelectric, wind farm electrical infrastructure). The group is differentiated by long-tenured nuclear qualifications covering the full fuel cycle and by the density of its French maintenance network servicing more than 10,000 sites.

Revenue is generated primarily through project-based engineering and systems integration work plus multi-year managed services and maintenance contracts, with pricing determined per project and per scope rather than via published rates. Go-to-market is direct enterprise field sales targeting industrial operators, infrastructure owners, defense and naval customers, energy producers, food processors, healthcare and public-sector clients; key accounts include EDF, CEA, Orano, Framatome, Naval Group, Chantiers de l'Atlantique, TotalEnergies, Siemens Energy, SNCF, the Palace of Versailles, and Paris CDG. The business model combines lumpier project revenue with the recurring stability of long-term maintenance and multi-site contracts, which together underpin a diversified vertical mix across energy, nuclear, marine, defense, food, healthcare, and infrastructure.
