SaaS Companies Using Sanity in the UK: 70 Active Firms (2026)
SaaS companies using a structured CMS sell subscription cloud applications in the UK with content-led websites for growth and support.
For SaaS sellers, a structured headless CMS tends to sit between marketing operations, documentation, localisation and product education. Adoption signals a company with enough developer capacity to separate presentation from content modelling, and enough go-to-market maturity to care about reusable material across landing pages, help centres, release notes and sales enablement. The buying centre is usually split between product marketing, growth, engineering and customer support, with finance involved once the website becomes part of conversion and retention infrastructure. These users are more likely to sell to mid-market, public-sector or regulated-industry buyers than to rely on a purely self-serve consumer motion.

Across the UK, 70 actively trading SaaS firms run this structured CMS. Together they report 1,195 employees, giving the adoption base a visible but still fairly lean operating footprint. Within the SaaS CMS category, it has a 1.8% detected share against a 3,900-company denominator, placing it sixth in the category ranking rather than among the default website systems. Registration is tilted towards London, which accounts for 52.9% of the cohort, followed by the South East at 15.7%, Yorkshire and The Humber at 7.1%, the South West at 5.7% and the North West at 4.3%.
UK SaaS suppliers are not licensed as a single sector, so obligations follow the activity and customer base rather than the software model alone. Companies running a structured CMS on public websites usually need to consider UK GDPR and the Data Protection Act 2018 where forms, analytics, support journeys or account-linked content involve personal information; the ICO is the relevant UK regulator. Cloud dependency also sits within a competition-policy backdrop. The CMA closed its public cloud infrastructure services investigation on 31 July 2025, reported an adverse effect on competition leading to remedies, and recommended strategic market status work on major cloud infrastructure providers.
Adoption appears concentrated among SaaS firms with developer capacity, content-led acquisition and a need to reuse material across marketing, documentation and support. The pattern tends to favour product-led and API-first businesses over brochure-site operators, but the small installed base suggests that general-purpose CMSs still carry most default procurement decisions. Further movement is likely to come from migrations that combine website performance, localisation and documentation governance, rather than from sector-wide replacement. Procurement may also become more cautious where cloud dependency, personal-information handling and customer audit requirements sit close together.
Adoption by company size
Adoption of Sanity rises with company size across the trading UK SaaS companies in this cohort. 0.1% of the 37,913 companies with under 10 employees run Sanity (41 detected). 1.2% of the 1,886 companies with 10–50 employees run Sanity (23 detected). 2.4% of the 166 companies with over 50 employees run Sanity (4 detected). That is a 2.3% gap between the over 50 employees and under 10 employees bands.

Key facts
About 8% of the trading cohort reports turnover above £5M (6 of 70 firms) — the rest sits below that revenue band.
11% of the cohort was incorporated since 2022 (8 firms), so a sizeable share is in its first few filing cycles.
Among 3,900 SaaS firms where a CMS is detectable, this structured CMS has a 1.8% share; the five higher-share systems range from 4.3% (166) to 60.2% (2,347).
London accounts for 52.9% (37) of structured-CMS-running SaaS firms, followed by the South East at 15.7% (11).
Co-occurring stack signals point to product-led distribution: 65.7% (46) also run tag-management tooling, 55.7% (39) use a front-end deployment platform and 54.3% (38) use web performance or security infrastructure.
AI & Machine Learning overlaps with 40.0% (28) of this SaaS cohort, while Fintech appears in 21.4% (15).
The ICO is the relevant UK data-protection regulator; SaaS suppliers processing personal data must consider UK GDPR and Data Protection Act 2018 obligations.

How Sanity 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.
