Companies Using Duda in Cardiff: 73 Active Firms (2026)
Cardiff companies running managed website-builder platforms maintain public websites for marketing, content updates and enquiry capture across the metropolitan area.
Adoption tends to sit with marketing, operations and owner-managed leadership rather than engineering teams. A managed site-builder gives these organisations a controlled way to publish service pages, refresh content, route enquiries and support local search without maintaining a custom web stack. In this cohort, the buying centre is usually practical: service-led SMEs, education providers, wholesalers and leisure operators need editable pages, forms, basic analytics and agency access. Running the platform therefore signals a company with enough go-to-market activity to care about web conversion, but not necessarily the budget or staffing model for in-house front-end development.

Cardiff has 73 companies running the managed website-builder platform, a small local adoption base rather than a broad software cluster. Among those with headcount disclosure, reported employment totals 645 people, which points to a cohort weighted towards owner-managed firms and small employers rather than large digital teams. Field services and trades form the most visible sectoral tilt, followed by construction, education and training, wholesale and distribution, and sport and leisure. That mix fits the use case: local discovery, proof of service, quote requests and periodic content changes matter more than bespoke product-led web engineering.
Procurement is usually less formal than for enterprise software, but ownership questions still matter. Companies running a managed site-builder often rely on an external web agency or a non-technical administrator, so contracts need to clarify domain control, portability of content, access rights and handover if the agency relationship changes. Privacy and cookie obligations are relevant where forms, analytics tags, newsletter sign-ups or booking widgets collect personal information. Consent wording, retention periods and access permissions can become operational issues, particularly where marketing automation tools sit alongside the website platform. For education and training users, accessibility and archiving expectations can sit alongside cost.
Managed site-builder adoption appears likely to remain tied to practical marketing needs rather than platform experimentation. Many Cardiff users look like service businesses where the website is a shop window, enquiry route and content surface, not a software product in its own right. Migration pressure tends to come from agency changes, rebrands, search visibility concerns and dissatisfaction with editing workflows. Bundling across hosting, analytics, forms and email tools may pull some users towards broader suites, while agency-led builds keep others on specialist managed platforms. The limiting factor is less technical capability than organisational appetite for changing a site that already performs an adequate job.

How Duda 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.
