What STUDELEC does

SEO Group is a privately-held French industrial group headquartered in Colomiers, in the Toulouse aerospace corridor, that designs, produces, and maintains critical electronic, electrical, and mechanical systems for European aerospace, defense, and industrial customers. Founded in 1994, the group operates through two wholly-owned subsidiaries: Studelec SEO, leading conception and engineering (mechanical and electronic design, CAD mechanical and electrical, PCB routing, technical documentation, NATO codification), and Sotrem SEO, leading industrialisation and production (electrical kitting, harnesses, electronic cards, systems integration, and AIT). At approximately 100 employees and €11.5M in annual revenue, the operating model is built around long-running technical programs with stringent quality and qualification requirements.

The commercial motion is enterprise field sales targeting large industrial groups, ETIs, SMEs, and startups, with technical sales engineers scoping custom projects from functional analysis through series delivery. The customer base is concentrated on European prime contractors including Airbus, Thales, Safran, KNDS, CNES, and Vitesco, with named use cases covering embedded systems, test benches, simulators, custom tooling, harnesses, and enclosures. Beyond initial design and manufacturing, the group offers MCO/MRO maintenance, obsolescence treatment, media duplication, and retrofit, converting one-off project revenue into lifecycle support streams. Pricing is non-public and project-based across engineering, production, and support services.

STUDELEC, the engineering arm of the group, operates in workshop and cleanroom environments with NATO codification expertise to support regulated defense and aerospace procurement. The company is private with no external funding, no recorded M&A, no partnerships disclosed, and no public listing; ultimate beneficial ownership and capital structure are not in the input data.

Core offering

STUDELEC designs, produces, and maintains critical electronic, electrical, and mechanical systems for aerospace, defense, space, and industrial customers. Through its two subsidiaries (Studelec SEO for engineering and Sotrem SEO for production), it delivers the full lifecycle from functional analysis and CAD/PCB design through industrialization, wiring, integration and AIT, to functional testing and MCO/MRO lifecycle support including obsolescence management and retrofit.

Product overview

STUDELEC (as part of SEO Group) operates as a dual-subsidiary industrial group combining Studelec SEO (engineering) and Sotrem SEO (production) to offer a complete lifecycle service for critical electronic, electrical, and mechanical systems. The portfolio spans three principal domains: (1) Conception & Ingénierie covering mechanical/electronic design, CAD, PCB routing, and NATO codification; (2) Industrialisation & Production for kitting, wiring, integration, and AIT; and (3) Tests & Maintenance for functional testing and MCO/MRO. These core capabilities are delivered through four service offerings: Systèmes & Équipements (custom embedded systems and test benches), Support & Cycle de vie (lifecycle extension and obsolescence management), Production & Câblage (electrical production from prototype to series), and Services & Assistance (training and quality support). The company serves major clients including Airbus, Thales, Safran, KNDS, CNES, and Vitesco.
