How we build websites now: every visitor gets the version of the story they came for.
keferboeck.com
A homeowner planning an extension, a developer comparing contractors and an architect looking for a partner all arrive with different questions. Your site should notice which one it is and answer that first. This page is doing exactly that for you right now.

What you actually get.
The headline numbers are the start. Underneath, every Facet earns its keep, costs less to run, and is safe to hand to an auditor.
It does not sit there waiting. It reads each visitor and walks them to the decision, the way your best salesperson would in the room, on every visit, at any hour.
Every section is placed where a decision happens, so far less of your hard won traffic leaks out of the funnel before they act.
They stop being two teams passing files. A change goes from idea to live in your brand voice without a queue, a ticket or a bottleneck.
It connects to GrowCentric.ai to generate the banners and assets and set up the campaigns across Google, ChatGPT ads (UK and US), Meta, LinkedIn and TikTok, tracked and A/B tested against matching website content.
Less manual work on assets and campaigns means real savings on staff, agency fees, and the employer costs and taxes that come with them.
The site is yours, in your repository. No CMS licence to rent, no lock in, and nothing to lose if you ever choose to take it elsewhere.
Built on a hardened Rails stack, not a tower of plugins, so it is not exposed to the constant stream of attacks that WordPress and its add ons attract.
No template ceiling. Whatever the business needs it to do, it can do. The sky is the limit.
Every release is version controlled with release notes, a clean audit trail for insurers. And the work is covered by insurance that permits handling sensitive data, backed by a documented, compliant process.
Most construction websites are a gallery of finished projects, and then nobody knows which enquiry was worth calling back.
Three different budgets and three different questions, one drone shot of the last big site, and the homeowner leaves because it all looks too big for them.
The ad says fixed price extensions, the page opens on the commercial portfolio, and the visitor who clicked never finds the promise.
Word of mouth, the trade directory and the ads all arrive as the same phone call, so the marketing budget follows habit rather than results.
A page that walks people through a decision, one section at a time.
A brochure lists things. A story guides someone from the problem they arrived with to the step they are ready to take. Every section is placed where a decision happens, so the next thing on the screen is always the next thing on the visitor's mind.

The same 1,000 visitors
Indicative "up to" ranges, not a promise.
Numbers that are always real, so decisions are always yours.
Every placed section reports back, in more than one way at once, so a blocked tracker or a declined banner never leaves a hole in the picture. What you see happened. What you decide is based on that.
The site knows where a visitor is, and remembers them when they come back.
Behaviour on the placed sections tells the site whether someone is just looking, weighing it up, or ready to talk. And a returning visitor who agreed to be remembered gets the site they know, not a stranger's homepage.
Remembered only with her consent, first party only, nothing stored before she agreed.
Personalisation without being creepyThe page continues the promise the visitor came in with.
An ad about extensions lands on a page about extensions. A post about commercial fit outs lands on a page that talks to developers. Same firm, same site, different emphasis, before the first word is read.
Pick who is visiting. The section reshapes itself. Then try it for real: this whole page reloads as that visitor sees it.
I'm Georg. I help ambitious businesses grow on evidence, not hope.
Fourteen years turning ideas into businesses that grow, as one person who gives your project everything. No agency, no handovers, and you own everything I build.
This is the real copy from the homepage of this site, not a mock up.
Back to the page everyone seesEvery layer is tested properly, so the winner is data, not a hunch.
A story section, a headline, a preview, a call to action: each can run as two versions against real enquiries, each visitor kept on one version, and a winner declared only when the numbers can carry it.
Personalisation people agree to. Editing nobody has to learn.
First party only, nothing before agreement, no fingerprinting, no bought data. A visitor who says no gets the full site, just the version everyone sees. In DACH that is not small print, it is the reason people trust the site.
Not yet agreed: the page everyone sees
Copy and images change through your client portal: you describe the change, a draft appears in your brand voice, you approve, it goes live. That is how these sites are run, and this site is the first one it is being built for.
The boring parts, done properly, because that is where sites quietly leak.
Built to load fast on a phone and to meet the accessibility standard the law now expects, in both languages.
Every behaviour is written down and checked automatically on every release, so a fix never breaks something that worked yesterday.
The moment a visitor hits a problem, the report arrives with the full context, usually before a second visitor ever sees it.
Documents, releases, decisions and the numbers, in the same client portal the rest of the work lives in.
You own the build and everything around it, and it is written for the next person to pick up cold. No hostage code.
Every release is versioned and written up, and the critical parts are verified before they go live.
Enterprise discipline, one person
Anyone can promise quality. I run every engagement through systems that prove it: a real client portal, legal clarity before work begins, and evidence for every release. This is what working with me actually looks like.
Every client gets a seat in the Keferboeck Hub: onboarding, documents, dashboards and live project links in one place. Structured from day one, so nothing important ever lives in a lost email thread.
Contracts, terms and insurance documents live in a portal vault. Signed versions are locked forever, every view and download is logged, and onboarding includes a formal review and acceptance step, with the option to hand it straight to your legal team.
Production releases are versioned, timestamped and written up: what was added, what changed, what was removed. You can always answer the question "what exactly went live, and when", because the record exists.
The full TDD and BDD suites must pass before anything reaches production, and the runs are recorded as evidence, with coverage tracked. A release that has not proven itself does not ship.
Critical business logic, how a calculation works, which legal documents a signup binds, is written up in plain language, approved by you, frozen at that state, and exportable as a PDF in English and German for your auditor. Changes reopen the approval, so the record never drifts from reality.
Major production releases get web application security testing on top of the automated suites, grounded in formal offensive security training. Systems that hold customer and payment data deserve nothing less.
A comprehensive insurance package is in place through the broker JMG: professional indemnity, public liability, employers liability and cyber cover. The insurer knows explicitly that my systems handle accounting grade workloads for SaaS products, loan interest and repayment calculations included, so exactly that work is covered.
Everything is documented: architecture, decisions, processes, tests and the code itself, all written for the next person to pick up cold. If anyone else ever needs to take over, for any reason, the handover is instant and smooth. No key person risk, no vendor lock in, no hostage code. Very few agencies can honestly offer that; almost no freelancer can.
The other side of that coin: I play a central role in every project and I take responsibility for it. I do not vanish the moment a better offer turns up. The setup is simply built to change as you grow. When the workload gets massive, parts of what I do can move in house, your team owns the day to day, and I focus on whatever challenge matters at that stage of the growth cycle. That is the plan working, not a breakup.
How working with me runs, in fullThe website teaches the advertising.
Which messages, which journeys and which previews turn into enquiries flows straight back into where the next budget goes. The site gets sharper, the ads get cheaper, and the two stop being separate projects. That loop is Growth Plus.
A good fit for some, and honestly not for others.
One monthly price that falls as the site carries itself
A smart website is a managed build, not a licence. The price runs in three phases like every package on the pricing page: £8,400 a month for the build, £7,300 a month while the first winners ship, £6,300 a month from month nine. In euros that is €9,700, €8,400 and €7,200. Final prices, and for EU business clients no VAT is added.
£8,400 a month. The workshop plan, the site built in five dimensions on Rails, the tracking and event strategy signed off by a data scientist, share images per page and message, A/B testing set up, AI editing through your portal, hosting, monitoring and documentation. PM and QA on every release.
£7,300 a month. Experiments running on real conversions, content shaped per stage and message, the first winners shipped, monthly reporting, and edits through your portal with your approval.
£6,300 a month. Hosting, monitoring, releases, edits, the engine kept sharp, and a quarterly review with the data scientist.
Optional from month 5: the campaign companion at £1,900 a month (€2,200), cancel monthly. Performance marketing on the site's own numbers, with ad spend paid by you directly to the platforms and never marked up. Every engagement starts with the free workshop, and you keep the plan whatever you decide.
