What Constellation does
Constellation is a French multi-specialist IT services group (ESN) founded in 2016 and headquartered in Saint-Cloud, France. The company targets French mid-sized enterprises (ETIs — Entreprises de Taille Intermédiaire) and selected large enterprises with a full-stack service offering spanning IT infrastructure, cloud and managed services, cybersecurity, data and applications, and digital transformation consulting. Operations are organized around four core business units (Fondations IT, Cloud & Infogérance, Transformation & Résilience, Data & Applications) and approximately 11 wholly-owned subsidiary brands delivering specialized capabilities, including Login Sécurité (cybersecurity/PASSI-qualified SOC), Novahé (IBM infrastructure integration), Easyteam (cloud migration and managed services), Clariteam (datacenter proximity services), Ekyo (carbon footprint management), STELR (executive IT consulting), Tyr Networks (sovereign connectivity), and Endexar (SAP environment management).
Revenue is generated through professional services engagements, managed-services contracts, and project-based consulting, delivered via direct enterprise field-sales teams and account managers across a 14-agency territorial network in Metropolitan France and one location in Mauritius. The group holds Platinum-level partnerships with Oracle and IBM, Gold partnership with Microsoft, and maintains a technology stack spanning IBM Power Systems, SAP, Azure, AWS (for FinOps), and proprietary platforms including the Tyr One unified network management console and the Ekyo carbon analytics platform. AI capabilities are deployed as feature layers within service offerings — including AI copilots for finance cycle automation and sovereign AI deployment — rather than as standalone products.
In 2024 Constellation became an Entreprise à Mission, legally committing to reduce carbon intensity by 50% by 2030, and the same year raised €116M from 3i Group (succeeding Qualium Investissement) to finance continued roll-up M&A. Reported revenue reached €212M in 2024 with 800 employees; the company serves 1,500+ clients across defense, retail, banking, pharmaceutical, construction, and public-sector verticals, with marquee engagements including Dassault Aviation (20+ years), Decathlon, CNETP, Banque Fiducial, Seqens, and Bonduelle.
