Senior hands. No layers.
/ DUV-in / Welsh, verb. to cite, to quote, to reference as a source. A fitting name for a studio whose job is to get your business referenced by AI.
Dyfyn is a small UK studio built around 25 years of hands-on software and web development.
Google will try to send you to DFYNE, the Glasgow gym-kit brand. Same-looking letters, different word. This one is Welsh — to cite — and a Cardiff studio. If you typed dyfyn.co.uk you are in the right place.
I've spent my career building systems where reliability matters — from large enterprise environments to modern web applications, AI integrations and lead-generation platforms.
Today, I'm applying that experience to a different problem: how do you make a small business more visible to AI — and how do you use AI to make the business itself more efficient?
That's Dyfyn.
What that looks like in practice.
Get found. Then get the graft off the team. The day together is how we tell which of those you actually need.
Google still has one of our own finance sites on page six. In the answers we measure, the assistants name it 51% of the time — in front of the names that own the blue links. The receipts are on the case study.
Microsoft. Open source. Web3. AI.
Four stacks. Same hands. The current work only makes sense if you can see the ones before it.
Microsoft
A decade inside BT Global Services on enterprise .NET, SQL Server and networking — the kind of work where a failed deploy is a national incident, not a blog post. Then Azure: App Service, SQL, Blob. Solid engineering. The licensing and egress never got cheaper.
Open source
The move was practical, not ideological. Next.js, Postgres, modern cloud. Sites that render for machines as well as people, hosted without egress eating the margin. Every property we run now sits on that stack. The Azure-exit work we still do for clients is the same move we made ourselves.
Web3
Web3 is a capability, not the product. DeFi, smart contracts, cross-chain work and tokenisation — taken on when the problem actually needs a chain, not as a default. Most organisations don't need it. The work and the receipts are named below.
AI
How do you make a small business more visible to AI — and how do you use AI to make the business itself more efficient? That's the work now. Get cited, then put agents on the graft behind the scenes. We prove it on our own projects first.
Web3, blockchain & tokenisation.
We take on Web3 projects — including tokenisation.
Whether you're building a DeFi product, developing smart contracts, exploring blockchain, or looking to tokenise an asset, product, membership or business model, we can help turn the idea into a working product.
Our team has real-world experience across the ecosystem. Tom won a Chainlink award and took second place in Aave's Vaults track at ETHGlobal LFGHO, building a Yearn V3 GHO vault with a live front end. He has also built zkCert, a privacy-preserving academic credentials platform, and ZeroLink, a cross-chain project using Chainlink CCIP at ETHOnline.
We don't believe in using blockchain for the sake of it. Most businesses don't need Web3 — but when tokenisation, decentralisation or blockchain genuinely creates an advantage, we know how to build it.
Proved on properties we own.
Not a slide in the proposal. How the studio actually runs — on properties we own, before it's ever sold.
Own sites, first
Every technique we sell runs on a portfolio of sites we own. That's where we found out what actually moves a citation and what only sounds like it should. When a change is worth making, it's because we carried the cost of being wrong ourselves.
See the portfolio →Agents and automations, in production
Enquiries, follow-ups, research, documents, reporting. Built against the tools you already use — and run on our own sites first, which is how we know where a human still needs to stay in the loop.
AI agents →Current tooling, senior hands
Twenty-five years of senior development behind the integration, so the thing runs, fails sensibly, and you can still debug it six months later. Current tooling. The same person who scoped it still maintains it.
AI automation →The receipts, with sources.
Two of our own sites. Checkable audit scores. Linked case studies. No composite clients.
Audit scores are the same check we run on any URL — re-run them yourself with the Dyfyn AI checker. The full set of owned properties is on the portfolio.
The shift, plainly.
The problem most organisations don't yet know they have.
Search has changed
People still use Google. They also ask ChatGPT, Claude, Grok and Perplexity — and Google's own AI Overviews now answer above the blue links. Ranking still matters. Being a source the model can quote matters more, and most sites were never built for that.
The official source has to be readable
If the official page isn't structured for machines, AI cites whatever it can read — a listings site, a forum, last year's PDF. We make the official source the one that gets quoted. Rebuild when the foundation is wrong; otherwise we work on the site you have.
The studio, without the pitch.
No account managers. No junior team hidden behind the pitch. You deal directly with the person building the work.

The stack, in order
Microsoft at BT, then Azure, then the open web, then Web3, now AI. We didn't skip a layer. That's why the current work holds.

Proved on our own sites first
Citation and agents run on properties we own before we sell them. The case studies are linked. The audit is the same check we run on any URL.

UK studio. UK hours. UK VAT.
Based in Cardiff, working with businesses across the UK. Always the person building it on the other end of the email.
Why Welsh.
Dyfyn isn't a vanity Welsh-language brand. It's a deliberate piece of positioning.
Wales has a strong, growing tech scene, but most of the agencies in this space don't operate from here, don't price in pounds, and don't understand UK regulatory specifics like FCA disclosure quirks. Dyfyn does. We're bilingual where it matters, UK-VAT-registered, and deliberately accessible enough that you're always talking to the person actually building your site.
Cardiff-based, working across Wales and the wider UK. The longer version of that positioning — sectors, towns, the word itself — lives on the Wales page.
Not DFYNE. Dyfyn.
Google treats rare Welsh verbs as typos of famous clothing brands. This is the bit that stops that.
No. DFYNE is a Glasgow activewear brand (dfyne.com). Dyfyn is a Welsh verb meaning to cite, pronounced DUV-in, and a Cardiff studio that rebuilds UK business websites so AI search engines quote them.
Different spelling, different company, different job. The legal entity is DYFYN LTD, Companies House 17315626. If Google offered you gym kit, click “Search instead for dyfyn” — you were already typing the right word.
DUV-in. Welsh f is an English v; Welsh ff is an English f. The name is the verb ‘to cite, to quote, to reference as a source’ — which is the work.
Talk to the person building it.
No account managers. No junior team hidden behind the pitch. Book a day, or drop a line and we'll come back the same working day.
