Under 10 employees
18.8% of band
Among 1,123 marketing agency companies under 10 employees with a detected system, SiteGround leads on 18.8%. This band is where lower-median systems cluster, with Plesk at a 5-employee median and several 6-employee median systems in the profiled set.

24% of band
The 10–50 employees band covers 524 companies, with WP Engine ahead at 24.0%. Competition then runs through systems whose overall medians sit around 6–8 employees, including Amazon Web Services, Vercel, Kinsta and Cloudways.

How Hosting & PaaS usage is detected
Company data
Detected companies are joined to UK Companies House records and XBRL accounts data. Revenue and headcount figures come from the most recent filed accounts; where the company has not filed, values are estimated using a model trained on filed history and peer benchmarks and are labelled as estimates.
Detection
Firmbase crawls the public website of actively-trading UK companies and fingerprints the technologies present: tracking scripts, embedded forms, chat widgets, CMS markers and similar signatures. A company is included in this list when one or more of the technology's signatures are found on its site; closely-related variants of the same product are grouped under one name. Detection covers what is visible on the public web — a company using the technology purely internally, with no website footprint, will not appear. Counts are therefore a conservative floor, not a ceiling.
Freshness
Websites are re-crawled on a rolling basis and the underlying company data is refreshed from Companies House continuously; filings appear within days of submission. The list and its statistics are regenerated when the detected cohort moves meaningfully. You can see the last-updated timestamp near the top of the page.
