ATECSI

What ATECSI does

ATECSI (Aménagement Technique de Salles Informatiques) is a French specialist engineering and installation firm founded in 2005 that designs, builds, and maintains technical IT rooms, data centers, and control rooms for enterprise clients. The company operates from a Mérignac (Bordeaux) headquarters with regional offices in Paris and Lyon, serving a primarily French customer base across industries including satellite services and audiovisual production. ATECSI organizes its offering into three integrated service lines: Ingénierie (audits, feasibility studies, specifications, and project management), Travaux (physical installation covering IT room urbanization, control room fitting, compliance upgrades, energy optimization, and structured cabling), and Services (preventive maintenance, IT transfer, DCIM/AIM software integration, video wall control, and site decommissioning).

The technology stack is built around third-party platforms rather than proprietary IP: ATECSI is the certified French distribution and deployment partner for GESAB (Spain) control room and image wall systems and for EkkoSense (UK) digital twin and cooling optimization software, supplemented by DCIM/AIM tooling, copper and fiber structured cabling, and physical security systems. Engineering work is grounded in TIA-942-B, Uptime Institute tiering, and ECOVADIS Silver sustainability standards, with the firm holding CDCP, EXIN, ATD, and Uptime Institute accreditations.

The business model is predominantly project-based professional services (engineering and construction) supplemented by recurring multi-year maintenance contracts, all delivered via direct enterprise sales in France. Pricing is custom and quote-driven with no standardized public tiers. Distribution is heavily reliant on direct enterprise relationships, industry event participation (notably Data Center World Paris and London), and the GESAB/EkkoSense technology partnerships that broaden the addressable product surface within the French market.

Core offering

ATECSI designs, fits out, and maintains technical IT rooms, data centers, and control rooms for enterprise information systems. The company delivers end-to-end critical infrastructure services from initial audit and feasibility studies through project management, installation, energy optimization, and ongoing maintenance, primarily targeting enterprise clients in France across three service poles: Engineering, Works, and Services.

Product overview

ATECSI (Aménagement Technique de Salles Informatiques) is a data center and critical technical space design, engineering, and construction firm founded in 2005. The company operates as a single-service provider organized across three complementary poles: Ingénierie (audit, feasibility studies, technical specifications, and project management), Travaux (physical installation including IT room urbanization, control room fitting, energy optimization, cabling, and compliance upgrades), and Services (ongoing operations including proximity services, IT transfer, DCIM/AIM software, video wall control, maintenance, and site decommissioning). The portfolio is not a software platform with modular add-ons but rather an integrated suite of consultative, engineering, and hands-on technical services delivered from design through full lifecycle support.

Scale indicators2 records

Recent moves7 records

Expansion highlights4 records

Broad incumbents

• Equans (Equans Digital): Major European multi-technical services group with French data center infrastructure offerings. Overlaps with ATECSI's cabling, cooling, and DCIM integration work as part of a much wider portfolio.
• Spie ICS: Large French IT services and systems integrator with significant data center infrastructure capability. Competes with ATECSI for DC build and modernization projects but at materially larger scale and broader scope.
• Axians (Vinci Energies): Vinci Energies' ICT brand operating across Europe with French data center infrastructure services. Comparable to ATECSI on integration and managed services but with vastly greater scale and cross-border reach.

Direct peers

• APL Data Center: French specialist data center consulting and engineering firm offering audit, design, and project management for DC builds. Highly comparable to ATECSI's Ingénierie pole in scope, customer base (French enterprise), and service-only positioning.
• Cap Ingelec: French engineering firm providing design, construction, and commissioning for data centers, including energy-efficient DC builds. Closely comparable to ATECSI on engineering-led DC infrastructure delivery in the French market.

Others

• GESAB: Spanish manufacturer of 24/7 critical environment control room and video wall solutions and ATECSI's core technology partner. Adjacent relationship: GESAB enables ATECSI's control room offering rather than competing with it, though GESAB could in principle sell direct in France.
• Schneider Electric (EcoStruxure for Data Centers): Global infrastructure vendor whose DCIM software, power, and cooling products compete with components of ATECSI's offerings. Adjacent rather than direct — Schneider enables integrators like ATECSI but also competes via direct delivery.
• Eaton: Global power management vendor with strong European DC presence (UPS, PDU, monitoring). Supplies hardware that ATECSI designs around and integrates in French customer projects.
• Vertiv: Global provider of power, cooling, and IT management solutions for data centers. Comparable technology stack to what ATECSI integrates; potential partner and competitor depending on channel strategy.
• Rittal: German enclosure, power distribution, and IT infrastructure manufacturer active in European data center markets. Provides physical infrastructure components that ATECSI resells and integrates into DC builds.
