Companies Using Amazon S3 in Cardiff: 58 Active Firms (2026)
Companies using object storage in Cardiff run public websites that store and serve media or static assets through cloud-based storage.
Adoption usually sits with engineering, web operations and marketing-technology teams rather than a single procurement owner. For Cardiff users, object storage tends to support product sites, customer portals, document libraries, image-heavy pages and backup workflows attached to public web estates. Running this stack signals more than a brochure website: the buyer normally has staff maintaining cloud accounts, deployment pipelines and access permissions, with enough traffic or content churn for storage cost, availability and page performance to be visible operating issues. Engagements are typically practical, led by web rebuilds, platform migrations or content-delivery housekeeping rather than board-level technology programmes.

Cardiff has 58 actively trading companies running this object-storage stack on public websites. Their reported employment footprint is 988 staff, giving the cohort a visible but still specialised place in the local digital economy. The mix points to adopters with live web operations rather than storage vendors: firms using websites for documents, media delivery, client access, booking or internal workflows. Several have enough turnover to imply formal procurement and finance oversight, while many look closer to owner-managed or early-commercial organisations where the same small team may own cloud accounts, website performance and day-to-day content operations.
Object storage is not regulated in isolation, but the way Cardiff adopters use it can bring privacy, security and procurement obligations into scope. Public web estates that hold customer documents, account files or user-generated media need access controls, retention policies and auditability that line up with GDPR and ICO expectations. Procurement tends to sit inside a wider cloud-account relationship, so switching costs are usually shaped by permissions, application dependencies, cache settings and staff familiarity rather than by storage pricing alone. Where public-sector or regulated-sector customers are involved, evidence on hosting location, backups and incident response is likely to matter during supplier review.
Adoption appears likely to remain sticky where object storage is embedded in live applications, content workflows and customer portals. Migration pressure tends to come from cost control, governance concerns or a wider move between cloud estates, not from storage features alone. Cardiff users with smaller technical teams may prefer bundling storage, monitoring, analytics and delivery through fewer suppliers, while more mature operators are likely to separate controls for security, performance and resilience. The market therefore looks less like a replacement cycle and more like gradual estate tidying, with procurement questions pulled into wider cloud and web-platform decisions.

Key facts
About 5% of the trading cohort reports turnover above £5M (3 of 58 firms) — the rest sits below that revenue band.
8% of the cohort was incorporated since 2022 (5 firms), so a sizeable share is in its first few filing cycles.
100.0% of the Cardiff object-storage cohort also show the associated cloud infrastructure platform, so the signal points to deployed public web infrastructure rather than a single-sector buyer group.
46.6% also run a CDN or edge-proxy layer, suggesting that performance, caching and traffic-control requirements are common in this cohort.
Web measurement is common: 39.7% show analytics tooling and 37.9% show tag-management tooling alongside object storage.
The sector mix is spread across SaaS at 10.3%, with Travel & Hospitality, Wholesale & Distribution, Wealth Management and Startup each at 8.6%; sector tags overlap.
Financial-health bands are mixed: 25.9% sit in the stable band, while 20.7% are weak and 5.2% are distressed.

How Amazon S3 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.
Amazon S3 is a trademark of its respective owner. Firmbase is not affiliated with, sponsored by, or endorsed by the trademark owner.
