Constellation Tech Stack

French IT services firm scaling cloud, managed services, and AI integration

IT Services and IT Consulting Saint-Cloud 501–1,000 employees Founded 2016 Privately Held

Constellation is a 500–1000-person French IT services firm built around four business lines: IT Foundations, Cloud & Outsourcing, Data & Applications, and Transformations & Resilience. The stack is heavily infrastructure-focused—Check Point, Palo Alto, Fortinet, Citrix, plus AWS, Azure, and OCI—with emerging depth in security (SASE, ZTNA, IAM, bastion hosts). Active hiring across engineering and sales (28 roles posted in the last 30 days) paired with projects around Azure industrialization and AI integration suggests a push to productize managed services and move beyond custom consulting.
