Tamtam tracks 124 Marketing Services companies headquartered in London. This list ranks the 30 largest by number of employees on LinkedIn, led by Property Marketing Agency, Two Circles and Performance Marketing. Their median headcount is 562.

These London-based companies are primarily established firms in the marketing services sector.

## 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 13, 2026.
