Market leader by size

The leading Hosting & PaaS system shifts with company size: among UK Startup with under 10 employees, Amazon Web Services leads at 37.8% of the 728 with a detectable system; among UK Startup with 10–50 employees, Amazon Web Services leads at 40.7% of the 253 with a detectable system; and among UK Startup with over 50 employees, Vercel leads at 42.9% of the 7 with a detectable system.

Under 10 employees

Amazon Web Services

37.8% of band

Under 10 employees contains 728 companies with a detectable system, so it is the largest band and mostly reflects micro-startup choices. Amazon Web Services is first at 37.8%, while Amazon S3 and Vercel sit in the main competing set at overall shares of 25.3% (250) and 21.4% (211).

10–50 employees

Amazon Web Services

40.7% of band

10–50 employees covers 253 companies with a detectable system, with Amazon Web Services first at 40.7%. Competition still includes the same front group seen overall, with Amazon S3 at 25.3% (250) and Vercel at 21.4% (211) across the full detected scope.

Over 50 employees

Vercel

42.9% of band

Over 50 employees contains 7 companies with a detectable system, so Vercel’s 42.9% first-place share should be read as a small-band signal. The wider scope has 31 detected systems, but this band is too small to infer a settled hierarchy beyond first place.

How Hosting & PaaS usage is detected

Methodology

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.

What is the most-used Hosting & PaaS among UK startup companies?

Amazon Web Services is the most-detected Hosting & PaaS among UK startup companies, with 38.5% share (380 of 988 companies with a detectable system), ahead of Amazon S3 (25.3%) and Vercel (21.4%).

How many UK startup companies have a detectable Hosting & PaaS?

988 of 2,576 actively-trading UK startup companies (38.4%) have a Hosting & PaaS detectable from their public website. The remainder either run systems with no public web footprint or none at all, so detected share figures are a conservative floor.

What is a Hosting & PaaS?

Hosting & PaaS systems give UK startup companies somewhere to run websites, applications, APIs, storage and deployment workflows without owning the underlying server estate. For small teams, the job is to keep hosting, releases, runtime capacity and operational access manageable while products change.

How is Hosting & PaaS usage detected?

Firmbase crawls the public website of every actively-trading company in this scope and fingerprints the technologies present — scripts, widgets, booking and checkout flows. A company is attributed to a system when that system's signatures are found; systems with no public web footprint are not attributable, which is why every share figure on this page means share of companies with a detectable system.

Which has more UK startup companies, Amazon Web Services or Amazon S3?

Amazon Web Services: 380 detected companies versus 250 for Amazon S3, of the 988 UK startup companies with a detectable Hosting & PaaS.
