# List of subscription businesses in London
Tamtam tracks 544 subscription businesses headquartered in London. This list ranks the 30 largest by number of employees on LinkedIn, led by Vodafone, BT Group and RELX. Their median headcount is 6,081. Half of them were founded in 1999 or later.
These London-based companies predominantly operate in telecommunications, financial services, and information services, reflecting a concentration of large, established firms. Among them, Vodafone uses technology to connect people globally, BT Group provides global communication services, RELX offers information-based analytics, and LSEG provides financial indexing and analytic services. Many of these companies are major players with significant employee numbers.
A notable characteristic is the prevalence of companies with a long history, such as BSI, founded in 1901, ACCA, founded in 1904, and The Economist, established in 1843. This indicates a strong presence of mature organizations rather than newly emerging ventures, with a mix of sectors including media like Financial Times and wellness services like Nuffield Health.

## 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 11, 2026.
