What Sigma Informatique does

Sigma Informatique is a French-headquartered IT services and software publishing firm based in La Chapelle-sur-Erdre (Nantes region). Founded in the early 1970s and operated as a Société par actions simplifiée (SAS) under the SIG-ALTAÏR holding, the company operates three integrated business lines — software publishing, consulting and systems integration, and managed services — and serves mid-market and enterprise customers across regulated French verticals including healthcare, public administration, social housing, retail, services, and industry. Operations are delivered through five regional agencies across Nantes, Toulouse, Strasbourg, Lyon, and Paris, with roughly 700 employees and disclosed revenue of approximately €75 million.

The technology stack is anchored by Microsoft Gold partner status and a portfolio of proprietary assets: Lixa ERP (built on the open-source Axelor platform), Lixa ESG/CSRD for sustainability reporting, Speed WMS for warehouse management, Suite Linéa Finance for accounting, Imhoweb for the social housing vertical, Easydore, and the HOSTIZ sovereign cloud platform. Sigma owns and operates French datacenter infrastructure with HDS certification for health data, runs a 24/7/365 managed Security Operations Center, and has developed proprietary responsible-digital methodologies branded as EcoExpertises, EcoOps, and FinOps/GreenOps. The firm holds ISO 27001, ISO 9001, Label Numérique Responsable Niveau 2, and Happy at Work 2026 recognitions, and was cited by Exægis as a Leader in Managed SOC and Visionnaire in Cloud de Confiance.

The commercial model blends license and subscription revenue from proprietary software, time-and-materials consulting/integration fees, and recurring managed-services revenue from hosting, cybersecurity, and infrastructure outsourcing. Named customers include the Fédération Française de Football, Groupe Libaud, Mutuelle Garance, and Ageneau Group. Historical growth has been supported by acquisition — Cinatis (2017), Actium Developpement (2011), Eirsys Technologie (2007), and Delta Ressources (2006) — supplemented by a reported €6.7M investment from Crédit Mutuel Innovation in 2016. Sigma reports a carbon intensity of 45 kgCO2e/k€ versus a 141 kgCO2e/k€ sector average, positioning operational efficiency and responsible-IT as marketed differentiators.
