The Information Services companies in France listed here are mostly mid-sized to large firms, with several established before 2000. Their activities range from data management and business intelligence to specialized expert assessments and sustainability ratings. For instance, AFNOR Group focuses on standardization and certification, while EcoVadis provides business sustainability ratings. Lefebvre Dalloz offers legal and tax knowledge, and Altares - Dun and Bradstreet specializes in data collection and analysis.

Tamtam finds the decision-makers at every company on a list like this one, with verified emails, phone numbers and the buying signals that tell you when to reach out.
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 15, 2026.
