B2B Companies Using Platform.sh in the UK: 107 Active Firms (2026)
B2B companies using managed cloud application platforms sell products and services to other organisations across the UK.
Adoption usually sits at the point where marketing, engineering and IT operations overlap. For business-to-business suppliers, a managed cloud application platform handles hosting, deployment pipelines and web operations for sites or applications that need controlled releases rather than occasional brochure-page updates. Running this stack tends to signal a more developed digital operating model: version-controlled code, multiple environments, agency or in-house developer support, and buyers in IT, web operations, security and procurement. It is most consistent with lower mid-market to enterprise organisations selling software, professional services, data services, telecoms or financial services into corporate accounts.

UK adoption is a small, specialist slice of business-to-business web operations: 107 active UK companies run this managed application platform. The system sits eighth in detected PaaS use within the sector, at 1.3%. Registered-office distribution is tilted towards London at 25.2%, followed by the South East at 19.6%, the North West at 14.0%, the East of England at 10.3% and the East Midlands at 7.5%. Reported headcount totals 1,093, pointing to a cohort that spans small specialist teams and larger employers rather than hobby deployments.
Business-to-business activity does not sit under a universal UK licence obligation. The relevant rulebook follows the underlying activity: financial services, telecoms, data processing and professional services each pull different duties into procurement and operations. For marketing and customer communications, ICO guidance treats PECR as covering live or automated calls, electronic mail and fax. Electronic-mail consent is not required for corporate subscribers, but senders must identify themselves and offer a valid opt-out route. UK GDPR still applies when business-contact data contains personal data, and live calling needs screening against CTPS and TPS where applicable.
Adoption appears likely to remain selective rather than universal. Managed deployment, content operations and security workflows tend to retain users where web estates are complex enough to justify specialist hosting and release management. Some use may be absorbed by broader cloud and developer platforms, particularly among firms standardising procurement. Among smaller organisations, simpler hosting and static-site options can be cheaper, which should keep this stack concentrated around companies with ongoing development cycles, agency support, regulated customer communications or a direct-channel sales posture.
Adoption by company size
Adoption of Platform.sh rises with company size across the trading UK B2B companies in this cohort. 0.1% of the 76,784 companies with under 10 employees run Platform.sh (70 detected). 0.1% of the 31,788 companies with 10–50 employees run Platform.sh (29 detected). 0.2% of the 3,773 companies with over 50 employees run Platform.sh (9 detected). That is a 0.1% gap between the over 50 employees and under 10 employees bands.

Key facts
About 18% of the trading cohort reports turnover above £5M (20 of 107 firms) — the rest sits below that revenue band.
6% of the cohort was incorporated since 2022 (7 firms), so a sizeable share is in its first few filing cycles.
Among 8,254 B2B suppliers with a detectable PaaS system, this managed cloud application platform accounts for 1.3% (107), behind seven other detected systems.
Registered-office concentration is highest in London at 25.2% (27), followed by the South East at 19.6% (21) and the North West at 14.0% (15).
Overlapping sector tags put Wholesale & Distribution at 37.4% (40) and Advanced Manufacturing at 21.5% (23), with IT Services & Managed Services on 10.3% (11).
The stack pattern points to web-operations use: tag-management technology appears on 82.2% (88), edge-network services on 58.9% (63) and open-source CMS tooling on 49.5% (53).
For B2B marketing, ICO guidance says PECR electronic-mail consent does not apply to corporate subscribers, but UK GDPR still applies where business-contact personal data is processed.

How Platform.sh 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. B2B 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 B2B 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.
Platform.sh is a trademark of its respective owner. Firmbase is not affiliated with, sponsored by, or endorsed by the trademark owner.
