# The 50 largest Information Services companies in Île-de-France

Tamtam tracks 80 Information Services companies headquartered in Île-de-France. This list ranks the 50 largest by number of employees on LinkedIn, led by EcoVadis, AFNOR Group and BCA Expertise. Their median headcount is 56. Half of them were founded in 2006 or later. The most common headquarters are Paris (27), Courbevoie (3) and Boulogne-Billancourt (2).

These Information Services companies in Île-de-France primarily offer business intelligence, legal and tax knowledge, and sustainability ratings. The list includes a mix of established mid-sized firms and younger companies. EcoVadis provides business sustainability ratings, while AFNOR Group specializes in standardization and certification. Lefebvre Dalloz offers legal and tax knowledge, and Altares - Dun and Bradstreet focuses on global business data.

A notable pattern among these companies is their diverse range of specializations within information services, from vehicle damage assessment by BCA Expertise to environmental intelligence by Kayrros. Many companies, such as EDD and Groupe Moniteur, focus on providing specialized information and solutions for specific professional sectors.

## 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.
