What Nexio Group does
Nexio Group, founded in 2003 and headquartered in Toulouse, France, is an independent engineering services and software firm specializing in electromagnetic compatibility (EMC), radio frequency (RF), lightning protection, and radar cross section (RCS). The company operates three French offices (Toulouse/Occitanie, Trappes/Ile-de-France, and Saint-Martin-d'Hères/Rhône-Alpes) and claims a presence in 25+ countries. Its proprietary software portfolio spans two families: BAT-EMC (with BAT-RADIO and BAT-SCANNER modules) for automated EMC/RF test execution, and CAPITOLE-EM (with CAPITOLE-RF and CAPITOLE-RCS) for electromagnetic simulation, incorporating proprietary KRON and ACA numerical methods developed through collaborative R&D.
The company generates revenue across three streams: (1) one-time software licensing for BAT-EMC and CAPITOLE simulation suites, (2) engineering services including technical assistance, EMC/RF studies, consulting, laboratory measurements, and R&D project support, and (3) professional training delivered through 13 course themes with 50+ annual sessions (priced at €1,050-€1,300 per participant). Customer base spans French aerospace and defense primes (Airbus, Thales, Safran, ArianeGroup, Dassault Aviation, DGA, Nexter), automotive OEMs (Renault, Valeo, Continental), electronics manufacturers (NXP, ACTIA), and independent testing laboratories. The company holds ISO 9001:2015 and QUALIOPI certifications and operates state-of-the-art EMC and radio testing laboratories.
Nexio has participated in 15+ collaborative R&D projects since 2008 with partners including ONERA, LAAS-CNRS, IRSEEM, XLIM, and major European OEMs, most recently the NEX-UP power electronics project launched in 2020 under France's Recovery Plan. The firm is founder/management-controlled under CEO Frédéric Amoros-Routié, with €681,819 in share capital, no external institutional investors, and no disclosed funding rounds. Its operating geographies extend across Europe, North America, Asia Pacific, and South America, with recent North American outreach via IEEE EMC+SIPI 2026 in Dallas.
