Proof over promise
Nothing here is called done without proof. Every delivery passes through a chain of checks — type checking, tests, security gates — and you see the report. "It works" is a measurement here, not an opinion.
We design and build AI solutions, websites and applications for organisations that don't want a demo that merely impresses, but a system that clearly works and can grow responsibly. Everything that moves here is our own code — including this universe behind the text.
Own code. Clear boundaries. Measurable delivery.
Scroll — the universe travels with you
No promises you have to take on faith. Principles you can check — on every project, at any moment.
Nothing here is called done without proof. Every delivery passes through a chain of checks — type checking, tests, security gates — and you see the report. "It works" is a measurement here, not an opinion.
The separation between clients lives in the database itself, not only in the code. Even a mistake on our side cannot carry your data to someone else. That is not a setting — it is the foundation.
Our AI executes nothing that costs money, leaves the building or is irreversible without your approval — recorded per action, with an expiry date. Automation without control is not a service, it is a risk.
To us, luxury is not decoration but precision. This is what that looks like in practice.
Every delivery passes up to eighteen checks — scaled to the risk profile of your project.
Work by our AI is reviewed by a second, independent system. The maker never approves its own work.
One responsible person who knows your project — no passing around, no noise between layers.
What we cannot demonstrate, we do not say. When in doubt, you hear it first.
An assistant under your own name that handles customer contact, qualifies requests and prepares quotes — while you do the work your customers come for. For local service businesses that lose requests to a busy day.
A landing page or company site that has to bring in customers today — own code, no template, fast and accessible, and built to be found.
A world like this one — computed in real time in the browser, no video, no library. For brands that have to be unforgettable.
Portals, dashboards and internal systems that carry your work instead of slowing it down — with the same quality chain as all our work, scaled to the risk of the project.
We bring AI into your existing processes — with the boundaries in the right place. First understand what is going on, then build what makes the difference, never the other way round.
A site or AI system nobody maintains becomes a risk by itself. We keep what we build up to date, secure and measured — for a fixed monthly amount, agreed at intake, with a report you can read back.
Our own product, and the proof of our method. An assistant with a face, a voice and a character — who knows your business, thinks along, and only executes something when you approve it.
"Two matters are waiting for your approval, and one invoice deserves your attention today."
Not a chat window that promises everything, but a colleague who knows what is going on: he reads the state of your business, weighs what deserves attention, and prepares work that you approve or stop with a single word.
Talk to him yourself
Below is Cell himself — the same system we use inside our own company, here with only the knowledge on this site. Ask him about our work, or ask him something that has nothing to do with us. That is fine too.
Cell answers here live. He can be mistaken, he cannot look at the web from this window, and we do not keep this conversation.
Eight steps, always in the same order — so you know where a project stands, even if you don't read along in the code.
What is going on, what it has to deliver, and whether it fits what we can honestly live up to.
The real situation mapped: existing systems, data, dependencies and risks.
Fixing the setup before building starts — including the boundaries of what the AI may and may not do on its own.
Structure and visual language, built on your real content — never on invented placeholder text.
Own code, in small, verifiable steps.
Up to eighteen quality gates — type checking, tests, security and accessibility — before anything goes live.
You receive the report of the checks, and after full payment the ownership of the work.
Optional, for a fixed monthly amount: we maintain what we built — up to date, secure and measured.
We don't need to look prettier than the market — only to show more honestly what you get for what. The market figures come from public European price surveys (2026).
Market picture (Netherlands, August 2026): AI receptionists €497–997 per month; website projects on average €6,000–7,700; AI agents €1,500–15,000+ one-off. Sources on request.
A standard website starts at €1,250, one-off. If you want a 3D world or immersive experience like this page, that starts at €3,500. Applications we build to measure: after a short discovery you hear one fixed price, and we prefer to start small and build on what works. The Dutch market average is around €6,000–7,700 per project; with our core offer we deliberately sit around that — with demonstrably more control over quality. After an intake you get one fixed price, no surprises.
The market asks €497 to €997 per month for an AI receptionist without its own platform. We publish our licence prices as soon as our cost measurement is complete — because we don't promise a price we cannot live up to. In the conversation you hear where you stand, with the calculation included.
Yes. For sites with their own content management we build on WordPress with our own theme — written from scratch, no bought template. You manage the content; we guard technology, security and speed.
Real-time 3D and motion that responds to the visitor — like the universe behind this text, computed in your browser without video or library. Needed? Only if your brand has to be unforgettable. If not, we'll tell you that too.
Because you see the proof: every delivery passes through a chain of checks — type checking, tests, security and accessibility gates — and you get the report. Nothing here is called done because we say so.
Tell us what is going on. Cell runs the Project Scan: a short, focused conversation after which you get an honest answer about what we can do for you — and what we can't. He knows our method, our prices and the small print.
