These London-based companies are primarily established firms in the marketing services sector. Their activities cover a broad spectrum, from digital marketing and content solutions to specialized areas like sports and entertainment marketing, and even emerging fields such as crypto and metaverse marketing. The companies mostly appear to be mid-sized to large firms rather than young startups.
Among these, Property Marketing Agency offers digital marketing for real estate professionals, while Two Circles manages fan data for sports organizations. Inspired Thinking Group (ITG) provides AI-powered content solutions, and Kantar Media focuses on cross-media audience measurement and data analytics. A notable pattern is the recent founding of Social Media Agency in 2022, indicating new entrants in specialized digital marketing.

Turn this list into pipeline
Tamtam finds the decision-makers at every company on a list like this one, with verified emails, phone numbers and the buying signals that tell you when to reach out.
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.
