These companies are critical infrastructure operators in the Moselle department, primarily large to mid-sized organizations. They encompass a range of essential services, predominantly in banking, healthcare, and public services. Notable examples include Banque Populaire Alsace Lorraine Champagne, a cooperative bank; CHR Metz-Thionville, operating multiple hospitals; UEM, an energy partner offering diverse services; and SDIS 57 - Sapeurs-Pompiers de la Moselle, providing emergency rescue services. OuiLab - biologie médicale is a group of medical biology laboratories, and Eurométropole de Metz is involved in government administration.
A significant pattern observed is the concentration of headquarters in Metz, suggesting it is a central hub for critical infrastructure operations within the Moselle department.

How this list is built
Every company on this list has a Tamtam company profile. The industry is the one the company gives on LinkedIn; categories such as SaaS or fintech are classified by Tamtam's AI from the company's website and LinkedIn page; and the headquarters city must match the company's own address. Companies are ranked by the number of employees on LinkedIn, and the list is refreshed every night. Classifications can be wrong, so treat the list as a starting point rather than an official ranking. Last updated Nov 11, 2026.
