# The 100 largest companies in the Bas-Rhin department

Tamtam tracks 1,381 companies headquartered in the Bas-Rhin department. This list ranks the 100 largest by number of employees on LinkedIn, led by Crédit Mutuel Alliance Fédérale, Groupama Grand Est and University of Strasbourg. Their median headcount is 453. Half of them were founded in 1975 or later. The most common headquarters are Strasbourg (59), Schiltigheim (6) and Illkirch-Graffenstaden (3).

The largest companies in Bas-Rhin primarily represent banking, insurance, and public services, alongside significant players in specialized manufacturing and retail. Many are well-established entities, with a notable presence of large groups. Crédit Mutuel Alliance Fédérale is a leading bancassurance provider, while Groupama Grand Est is a mutualist insurance company. Würth France specializes in fastening and assembly materials for professionals, and KUHN Group offers agricultural equipment.

A clear pattern is the strong concentration of headquarters in Strasbourg, which hosts major institutions like the University of Strasbourg, the Council of Europe, and several large financial service providers. This reflects Strasbourg's role as a major administrative, educational, and economic hub within the department, attracting diverse sectors from IT services with Euro Information Developpements to construction with SOPREMA Entreprises.

## 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.
