# Top 100 Advertising Services companies in Europe

Tamtam tracks 4,444 Advertising Services companies headquartered in Europe. This list ranks the 100 largest by number of employees on LinkedIn, led by WPP, Publicis Groupe and Clinic. Their median headcount is 2,073. Half of them were founded in 2001 or later. The most common headquarters are London (41), Paris (8) and Milan (4).

This selection of advertising services companies in Europe primarily features large groups, many of which are global networks. WPP, a creative transformation company, and Publicis Groupe, which helps clients transform their marketing and digital businesses, are prominent examples. Other notable firms include Clear Channel Europe, a leading outdoor media company, and Havas, a global communications network. This list highlights the diverse specializations within the sector, ranging from creative agencies to media buying and outdoor advertising.

A clear pattern among these companies is the concentration of headquarters in London, indicating its role as a major hub for the advertising industry in Europe. Publicis Groupe is based in Paris, Havas in Puteaux, and JCDecaux in Neuilly-sur-Seine. While some companies like BAR (Milan) and MERCADO (Lisbon) were founded in the 2010s, many of the largest firms have a longer history, with Clinic founded in 1983 and JCDecaux in 1964.

## 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 14, 2026.
