What LGM does

LGM is a privately held French engineering group founded in 1991 and headquartered in Vélizy-Villacoublay, providing management, engineering, digital, and training services to operators of complex industrial systems and critical infrastructure. The company operates across seven verticals — aerospace, railway, defense, energy, naval, space, and automotive — serving marquee clients such as Airbus, Dassault Aviation, Thales, Safran, Alstom, SNCF, RATP, EDF, Naval Group, CNES, and Stellantis, primarily through long-cycle consulting engagements under a professional services revenue model.

The group's offering is organized around six solution areas: Safety & Systems Excellence, Supportability & Asset Management, Projects & Performance, Critical Electronics, Digital & AI, and Consulting & Training. Underlying capabilities include proprietary methodologies (notably MBSDA, developed for IMdR with Airbus Protect, Thales, EDF, and others), the AI4LGM internal AI platform, the ADEL training-engineering solution aligned with the ASD S-Series S6000T standard, and CNES-certified space-grade electronics manufacturing at the Marville site. LGM Academy delivers 96 training modules across 12 domains with 210 sessions per year and 2,000+ trainees trained.

LGM employs approximately 1,650 people across seven countries (France, Germany, Belgium, Canada, Spain, India, Morocco), generating €170M in annual revenue (2025) with 8% reinvested into R&D. The company is founder-controlled (President Frédéric Arnaud; co-founders Frank Weiser, Eric De Tocqueville, Michel Monteillard) and CEO Stéphane Yansenne leads operations, with no external private equity or venture capital backing.
