List of data and analytics companies in Europe

Tamtam tracks 2,591 data and analytics companies headquartered in Europe. This list ranks the 100 largest by number of employees on LinkedIn, led by Capgemini, SAP and Atos. Their median headcount is 4,203. Half of them were founded in 1992 or later. The most common headquarters are London (29), Paris (6) and Amsterdam (5).

๐ŸŒ Europe100 companiesUpdated Nov 12, 2026

This selection showcases large European companies with significant operations in data and analytics, encompassing a range of industries. Capgemini, Atos, NTT DATA Europe & Latam, and Orange Business are prominent in IT services and consulting. Other notable firms include SAP, a software development company, and RELX, a provider of information-based analytics. The list also features Johnson Controls, specializing in smart building solutions, and Publicis Groupe, a leader in marketing and digital business transformation.

A recurring pattern observed is the concentration of headquarters in major European cities. Paris, London, and Madrid are frequently represented as headquarter locations for these large enterprises. The companies on this list generally represent established, large-scale operations rather than younger ventures, with several, like SAP and Wolters Kluwer, having been founded decades ago.

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.
