# List of managed service providers in Europe

Tamtam tracks 1,750 managed service providers headquartered in Europe. This list ranks the 100 largest by number of employees on LinkedIn, led by Capgemini, Orange and FUJITSU. Their median headcount is 3,306. Half of them were founded in 1995 or later. The most common headquarters are London (7), Paris (6) and Madrid (3).

This selection of European managed service providers predominantly features large IT services and IT consulting firms. Companies like Capgemini, Fujitsu, and Atos offer end-to-end services from strategy to operations, specializing in areas such as AI, cybersecurity, and cloud solutions. Telecommunications giants Orange and TIM also appear, providing a mix of digital services alongside their core offerings. The companies listed are generally large, with employee counts ranging from over 12,000 to over 340,000.

A notable pattern is the concentration of headquarters in major European cities. Paris, Madrid, and London are frequently cited, indicating these cities as key hubs for large-scale IT and telecom operations. While many companies focus on IT services, there is a clear blend of established telecommunications providers and specialized IT consultants, reflecting the convergence of these 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 12, 2026.
