ABMI

What ABMI does

ABMI Groupe SAS is a French specialty engineering services company incorporated in February 1985 and headquartered in Nanterre, France. The firm operates 12 regional agencies across France plus international offices in Brussels (Belgium), Bristol (United Kingdom, opened 2021), Toronto and Montreal (Canada), organised around 11 engineering centres covering operational performance, robotics and obsolescence management, infrastructure engineering, tools innovation with immersive reality, and industrial vehicles. ABMI serves industrial leaders, R&D teams and startups across five demanding verticals — Aeronautics/Space/Defence, Mobility, Energy, Chemistry/Oil & Gas, and Health — with named clients including Airbus, EDF, Framatome, Sanofi, RATP, Arquus, Veolia, Suez, SNCF, Alstom, Boeing, ArianeGroup, MBDA, Collins Aerospace and the European Space Agency.

The group's product portfolio combines traditional engineering services with two wholly-owned digital subsidiaries: Rtone (IoT and smart connected products, acquired 2020, Lyon, with 1,500+ products deployed) and Openium (native iOS/Android mobile applications, acquired 2024, Clermont-Ferrand, 34 employees). Revenue is generated through professional services engagements — outsourced project packages, multi-FTE service centre contracts billed in "Work Units" or per FTE, and flat-rate/fixed-price project scopes — typically structured as multi-year deals with enterprise clients in regulated sectors. Since 2023, ABMI has operated within HOUSE OF HR's HOUSE OF ABY ecosystem of 10 brands spanning 55 sites and nearly 20 centres of excellence, enabling cross-border delivery. The company holds ISO 9001 (since 2022), EN 9100, ISO 19443 (nuclear, June 2024), ISO 14001 (early 2026), CEFRI-E and MASE certifications, and has received the Ecovadis Gold Medal in 2024 and 2025. François Laborde serves as CEO and Chairman.

Broad incumbents

• ALTEN: Large European engineering and technology consulting group. Overlaps with ABMI across industrial verticals but at significantly greater scale and broader geographic reach.
• Capgemini Engineering: Engineering and R&D services arm of Capgemini, covering aerospace, automotive, energy, and industrial sectors. A scaled, broader-scope incumbent with overlap on the digital transformation (Rtone/Openium-equivalent) and traditional engineering mandates ABMI pursues.

Direct peers

• FEV: Engineering services provider for automotive, mobility, and energy sectors with strong digital and software-defined vehicle capabilities. Comparable to ABMI's combination of traditional engineering plus embedded digital/IoT competencies (Rtone/Openium equivalent).
• Akka Technologies (Akkodis): European engineering consulting and digital services firm, now part of Adecco/Akkodis. Directly comparable across mobility, aerospace, energy, and life sciences verticals with similar service centre and outsourced package models.
• AVL List: Austria-based engineering services firm focused on automotive, powertrain, and industrial sectors. Comparable as a specialist engineering firm delivering outsourced FTE and project-based services to large OEMs.
• Segula Technologies: French-headquartered engineering services group serving automotive, aerospace, energy, rail, and defence. Closely comparable in terms of multi-sector specialist engineering positioning and FTE-based delivery model.
• Assystem: French engineering services group focused on nuclear, energy, aerospace, defence, and transport infrastructure. Closest direct peer given overlapping vertical mix and similar French public-private customer base.
• Bertrandt: European engineering services partner with strong automotive, aerospace, and mobility focus. Comparable specialist engineering services model serving major industrial OEMs across France and Germany.
• Expleo: Engineering, technology and consulting services firm with strong French footprint across aerospace, automotive, energy, and industrial sectors; comparable in scope to ABMI's traditional engineering plus digital transformation offering.

Regional players

• SPIE: French multi-technical services group with energy and industrial services overlap. While more focused on technical facility services than engineering consulting, it competes for adjacent infrastructure engineering mandates with utilities and industrial operators.
