Half of them were founded in 2003 or later. The most common headquarters are Strasbourg (16), Schiltigheim (5) and Entzheim (2).

The professional services firms in Bas-Rhin are primarily large and mid-sized companies, with a strong presence in IT services, engineering, and home care. Euro Information Developpements, an IT subsidiary of a bank-insurance group, is a prominent example. Technology & Strategy provides engineering, digital, and consulting services, while Axima Réfrigération France specializes in industrial refrigeration.

## 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.
