Senior hands on the latest tech, built for the next era of search.
/ duv-un / Welsh, verb. to cite, to quote, to reference as a source. (The f is pronounced like an English v — Welsh f = v, Welsh ff = f.)
Dyfyn is a Welsh web studio that rebuilds UK business websites to be cited by AI search engines. The name is Welsh — chosen on purpose. In an era when ChatGPT, Claude, Grok, Perplexity and Google's AI Overviews are increasingly the surface where buyers find your business, getting cited is the whole game. We named the company after it.
Twenty-five years of senior development behind the work. A decade of that at BT Global Services on enterprise .NET, SQL, and networking — the kind of work where reliability matters more than fashion. The rest spent on the moving edge of modern web: every framework shift, every platform iteration, every new layer. Pragmatic about what works, restless about what's next. Latest tech as a default, not an experiment.
The origin, plainly.
A couple of years ago I was asked to build securedloanrates.co.uk — a lead-generation site for one of the genuinely impossible corners of UK search, the secured-loans market. Built it the way I build everything: from the foundations up. Fast, structurally sound, citation-ready. Nothing exotic — just careful technical work.
In Google's classical search rankings, it didn't stand a chance. The UK secured loans market is dominated by lenders and brokers with twenty-year-old domains, thousands of backlinks, and household-name authority. We averaged position 58 for our target terms. Page six. Effectively invisible.
Then a loan enquiry came through, and the prospect mentioned Claude had recommended us.
I checked the others. Same pattern. AI engines were citing securedloanrates.co.uk for queries we couldn't rank for on Google. The site was structurally readable to ChatGPT, Claude and Perplexity in a way that the larger competitors' older, slower, schema-light sites weren't. The exact features that made the site invisible to Google's incumbent-favouring algorithm — newness, lack of historical authority — didn't matter to the AI engines. They cared about structure, clarity, and citability.
That's when I started Dyfyn. The citation game is wide open right now while everyone is still fighting for Google rankings. We help UK businesses get into AI search engines before the field consolidates.
The shift, plainly.
The problem most UK businesses don't yet know they have.
Search has changed
ChatGPT now answers a billion questions a week. Claude, Grok and Perplexity take more. Google's own AI Overview summarises the answer above the blue links. The classic SEO playbook — ranking pages, hunting backlinks, optimising title tags — is still useful but it's no longer enough on its own.
Most sites aren't ready
The technical work that makes a site readable and citable by AI systems is specific, well-defined, and almost universally missing. We rebuild sites from the foundation up so the AI-readiness layer is the default — not a bolt-on.
Senior, hands-on, small enough to answer the phone.
Big agencies will charge £15k+ for a build like this and assign you to a junior. Cheap freelancers will undercut us and ship a Wix template. We sit in the gap.

25 years of development experience
Not a marketing agency that recently discovered AI. A working developer who's shipped through every web era from Perl CGI to React Server Components.
- 02
AI-leveraged delivery
We use AI tools throughout the build process — which means faster iteration, more design options for you, and projects delivered in weeks rather than months.
- 03
UK-based, UK-pricing, UK-VAT
No outsourced development, no time-zone delays, no surprise dollar invoicing. Welsh studio, working with UK businesses.

Real expertise in regulated sectors
We work extensively with finance and lead-generation businesses. We understand FCA disclosure requirements, the compliance copy quirks, the lead economics.
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.
Worth saying: this isn't a brand play. I'm Welsh — born here, always lived here, from a farming family. The studio runs the way that background runs: pragmatic, durable, plain about what it can and can't do.
A studio behind the wedge.
AI search optimisation is what we lead with because it's the most timely and differentiated work we do right now. It's not the only work we do.
The studio works across modern web platforms, AI integration (Claude API in production across multiple builds), legacy-to-cloud migration, and the broader UK financial services technology ecosystem we've shipped lead-generation sites in for years.
The studio also has Web3 capability through a developer team member who placed in an international Ethereum hackathon for secure smart-contract design — relevant for the small but growing pool of UK SMEs working with blockchain-adjacent products.
If you came through the AI citation conversation and you have a different problem to solve, we're often the right team to solve it. Have the conversation.

Drop a line and we'll come back the same working day. The first conversation is free, no commitment, and you leave knowing more about your site's AI readiness either way.
