A Cardiff studio, working with Wales.
Dyfyn is based in Cardiff and works across the country — with businesses, public bodies, and national organisations. When someone asks an AI for the official word, the official source has to be the one it cites. That is the job.
Stiwdio o Gaerdydd yn helpu busnesau Cymreig i gael eu dyfynnu gan systemau chwilio AI.
A Cardiff studio helping Welsh businesses be cited by AI search systems. That's what "dyfyn" means — see below.
Named sectors, across Wales.
Sectors we know well enough to lead with. Not an exclusive list.
Sport and national organisations
Governing bodies, unions, and clubs. Fixtures, tickets, eligibility, official statements. If the official source isn't ready for AI, engines cite a listings site, a fan page, or last year's PDF. We make the official version the one machines quote — in English, Welsh, or both, including where the Welsh Language Standards require it.
Cultural and public bodies
Museums, arts trusts, festivals, publicly funded organisations. Discoverability is a mission concern, not just a commercial one. Bilingual output is often part of the brief, and the Standards usually are.
Professional services
Solicitors, accountants, consultants. High-intent buyers who ask AI for a shortlist before they email anyone. If you aren't one of the names an engine returns, you aren't in the conversation.
Financial services
Regulated firms — brokers, IFAs, bridging lenders. FCA disclosure rhythm, lead economics, compliance-copy quirks. Portfolio experience here: the securedloanrates case study.
Tourism and hospitality
Hotels, B&Bs, restaurants. Bookings increasingly start with an AI recommendation. Structured content and local schema are what put the official listing in that answer.
Trades and food producers
Tradespeople, farm shops, producers. Local search is becoming AI-mediated: Google Business Profile still matters, and so does what ChatGPT says when someone asks for a Welsh recommendation.
The shape of the work.
The question the next person asks an AI. If the answer doesn't name the official source, that source is not in the shortlist.
A supporter asks ChatGPT: "when is the next home match, and where do I buy tickets from the official site?" If the official pages aren't structured for machines, the answer names a reseller, a listings site, or last season's dates. The official source has to be the one cited.
A homeowner in CF3 asks Siri at 11pm: "emergency plumber near me for a burst pipe." The device is asking an AI, not Google. Three names come back — LocalBusiness schema, proper service-area markup and a Google Business Profile with real reviews decide whose phone rings. See the trades page for the specific build, or local businesses for the wider UK market.
A visitor asks Claude: "where should I stay for a three-night walking trip in Snowdonia in October?" Whoever's cited in that answer wins the booking. Bookings pages, structured content, schema markup and honest reviews are what put you there.
A first-time buyer asks ChatGPT: "who's a good conveyancing solicitor in South Wales for a £180k house purchase?" The engine returns three names. If yours isn't one of them, you don't get the enquiry.

What dyfyn means.
Why the company is named Dyfyn.
/ DUV-in / Welsh, verb. to cite, to quote, to reference as a source.
Dyfyn is a Welsh verb meaning "to cite", "to quote", or "to reference as a source". The same root carries into dyfynnu (citing, quoting) and dyfyniad (a quotation, a citation).
In English, "cite" sounds clinical — academic footnotes, court rulings. In Welsh, the same word carries the weight of being chosen as authoritative: the source someone else picks when they need to back up what they're saying. That's the goal of every site we build.
Local context.
Two things that matter in Wales. Neither is a slogan.
Welsh Language Standards
Public bodies and many national organisations have specific duties to operate in Welsh. We can produce bilingual builds where that is the brief, with Welsh-language schema so AI systems parse both versions cleanly — English, Welsh, or both.
UK-based, UK-registered
VAT-registered, working in UK hours, talking to the person who'd do the work. Finance work sits in the portfolio if the brief is regulated copy; it is not the only brief we take.
