What ATIXIS does

ATIXIS is a France-based engineering and project management group, founded in 2012 in Paris and registered as a SAS (€300,000 capital), that delivers multidisciplinary construction consultancy across the full project lifecycle — from feasibility studies through to handover. The firm's service portfolio spans eight integrated lines: MEP engineering and fire safety, owner's representative / PMO, project management (maîtrise d'œuvre), BIM management and 2D/3D synthesis, design & build (general contractor), structural engineering, a proprietary digital/real-estate management offering under the COMBOS brand, and environmental engineering under the TERAO brand. Two specialized subsidiaries have been integrated via acquisition: SYCOB (BIM synthesis, joined 2021) and TERAO (sustainable development and low-carbon engineering, joined 2022 and operating on five continents), giving the group both domestic depth and international reach.

The business model is professional-services B2B: revenue is generated through fee-based engineering and project-management engagements sold via direct enterprise sales to large accounts and public-sector clients, with services delivered by teams deployed across six offices (Paris La Défense, Lyon, Rennes, Nice, Marseille, and Ho Chi Minh City). Underlying technology is BIM-centric (Building Information Modeling) with proprietary digital tools — COMBOS for real-estate management, document control, 360° Plan VR visualization and non-conformity tracking, and TER'ACV for predictive life-cycle assessment and low-carbon materials analysis. The group reports approximately 130 employees, around €14M in annual turnover, 300+ active clients, and 1,000+ completed projects, with named reference clients including EDF, SNCF, RATP, Amundi, AXA, Roche, CitizenM, Thalie Santé, ROXEL and the Normandy Bridge infrastructure project. Operations are supported by ISO 9001:2015 (since 2014), OPQIBI professional qualification (since 2018) and a 2022 EcoVadis Silver Medal; the company became an 'entreprise à mission' in December 2025.

Direct peers

• Setec Group: French engineering consultancy providing building, infrastructure, energy, and project management services through subsidiary firms (setec bâtiment, setec tpi, etc.). Closely comparable as a multi-disciplinary French engineering and PMO platform, with similar culture of technical specialization and office network.
• Burgeap (Ginger group): French environmental and sustainable-development engineering consultancy offering building and urban environmental assessments, LCA, and AMO services. Highly comparable to TERAO's environmental AMO/MOE practice, with similar French regulatory expertise and sustainability consulting positioning.
• Alterea (Energy & Environment): French energy and environmental engineering consultancy specializing in building energy efficiency, fluid systems, and sustainable operation. Highly comparable to TERAO's energy/sustainability practice and to ATIXIS's MEP engineering core, serving similar mid-sized French building retrofits.

Broad incumbents

• Egis: French engineering group operating across mobility, urban development, buildings, energy, and environment, with full project management, engineering, and operations capabilities. Directly comparable as a multi-disciplinary French PMO/MEP player, far larger than ATIXIS, and explicitly cited as a competitor.
• Arcadis NV: Global design and engineering consultancy with French operations (Arcadis AG5, IBI) covering buildings, sustainability, and project management. Comparable in offering integrated design, PMO, and sustainability services to enterprise clients across multiple sectors.
• Ingerop: Independent French engineering and project management group with building, infrastructure, energy, and environment practices. Directly comparable in scope of multi-disciplinary engineering and owner's-rep services, and named by ATIXIS as a larger competitor.
• Tractebel (Engie Solutions): Global engineering and consulting firm owned by Engie, operating across energy, water, infrastructure, and buildings with strong MEP and sustainability credentials via its EDR/Coyne-et-Bellier heritage. Comparable in providing integrated MEP and sustainability consulting, but at much larger scale and with deeper energy-sector DNA than ATIXIS.
• Artelia: Major French-headquartered engineering and project management consultancy offering MEP, structural, and PMO services across buildings, infrastructure, energy, and industry. Named by ATIXIS in its own competitive set as a larger incumbent, with a multi-thousand employee scale and global footprint that dwarfs ATIXIS.
• WSP Buildings (France): Global engineering consultancy with French buildings practice providing MEP, structural, environmental, and project management services. Comparable to ATIXIS across the same service stack and end-markets (healthcare, offices, transport) but at materially larger scale.
• Systra: French-headquartered transport and engineering consultancy providing project management and engineering for rail, urban transit, and infrastructure, with a strong owner's-rep and PMO practice. Comparable on PMO/owner's-rep services for French infrastructure and rail clients (e.g., SNCF, RATP) and a key competitor for that segment.
