SaaS Companies Using Kinsta in the UK: 105 Active Firms (2026)
Hosted SaaS suppliers sell subscription cloud software while running public websites on a managed hosting platform in the UK.
For hosted SaaS suppliers, managed website hosting usually supports the public-facing estate: marketing pages, documentation, customer education and conversion paths, rather than the core product environment. Adoption points to a business-to-business sales motion with enough web traffic, lead capture and security scrutiny to justify a managed layer, but not necessarily a large internal infrastructure team. Buying centres tend to sit between revenue operations, marketing operations and engineering, with procurement drawn in where enterprise or public-sector customers ask about uptime, data handling, sub-processors and contractual controls.

Across the UK, 105 actively trading SaaS suppliers run this managed hosting platform, making it a focused adoption cohort rather than a broad software-market proxy. Reported headcount totals 2,130 staff. Within a wider SaaS hosting denominator of 831, the platform ranks third among hosting systems at 12.6% share. The regional skew is London-heavy at 40.0%, followed by the North West at 14.3%, the South East and South West at 11.4% each, and the East of England at 5.7%. That distribution fits a sales-and-marketing website use case: concentrated in London, but with a visible regional base outside the capital.
UK SaaS suppliers using managed hosting are not licensed as a single category, but website operations often intersect with UK GDPR, the Data Protection Act 2018 and customer security reviews. The ICO matters where public sites collect leads, handle trial sign-ups, serve logged-in help content or pass personal data to processors and sub-processors. Cloud dependency also has a competition-policy angle. The CMA closed its public cloud infrastructure services investigation on 31 July 2025, reporting an adverse effect on competition and identifying remedies. For SaaS teams, the practical issue is less sector licensing than portability, auditability and dependency across hosting, analytics and infrastructure suppliers.
Adoption appears tied to SaaS suppliers that have moved beyond founder-led marketing but still prefer to keep public website operations outside the core engineering backlog. The category tends to move with website rebuild cycles, security questionnaires and content-led acquisition plans, so switching is likely to be episodic rather than constant. Bundled hosting, caching, security and publishing support may keep appealing to lean teams, while larger software suppliers may pull more of the web estate towards their main cloud and governance stack. Privacy-led measurement changes and customer due diligence should keep pressure on how these tools are configured.
Adoption by company size
Adoption of Kinsta rises with company size across the trading UK SaaS companies in this cohort. 0.2% of the 37,913 companies with under 10 employees run Kinsta (70 detected). 1.7% of the 1,886 companies with 10–50 employees run Kinsta (32 detected). 1.8% of the 166 companies with over 50 employees run Kinsta (3 detected). That is a 1.6% gap between the over 50 employees and under 10 employees bands.

Key facts
About 10% of the trading cohort reports turnover above £5M (11 of 105 firms) — the rest sits below that revenue band.
8% of the cohort was incorporated since 2022 (9 firms), so a sizeable share is in its first few filing cycles.
Among 831 SaaS firms with a detectable hosting system, this hosting platform ranks third by detected share at 12.6% (105), behind two larger alternatives.
The stack is content-led: 100.0% (105) also run a content management system, 98.1% (103) run a CDN/security layer and 86.7% (91) run tag-management tooling.
Registered offices cluster in London, which accounts for 40.0% (42) of the cohort; the North West follows at 14.3% (15).
Financial-health labels are mixed, with 37.1% (39) stable, 18.1% (19) weak and 12.4% (13) distressed.
UK SaaS suppliers do not face a single sector licence, but the ICO remains relevant where hosted software processes personal data under UK GDPR and the Data Protection Act 2018.

How Kinsta 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. SaaS companies are identified using Firmbase's semantic classification of company activity, built from filings, websites and registered SIC codes rather than SIC codes alone. The detected counts and share figures on this page are computed within that sector cohort, so "share" always means share of SaaS companies with a detectable system — not of all UK companies.
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.
