Build first,
present solution.

Other agencies start with workshops and PowerPoints. We start with code.

You don't get a concept paper — you get a working prototype. Only when you see what's possible do we talk about scope and budget.

Open source, no lock-in. Your website belongs to you. You can leave anytime — we earn your trust every single month.

Typical agency: kickoff → concept 4–6 weeks
Promptheus: kickoff → prototype 3–5 days
Typical agency: discovery workshop from €5,000
Promptheus: prototype + conversation 0 €

Three things. Done right.

No portfolio with 30 buzzwords. Three clear services.

Websites

Custom-built, modern, fast. Next.js, Tailwind, no template look. SEO-optimized and accessible from day one.

AI Integration

Intelligent automation for your business. From analysis to implementation — we find where AI can concretely improve your workflow.

Digital Maintenance

With Ember you maintain your website via chat. No CMS, no backend — you write what you want, the AI implements it.

How we work.

From first message to finished solution — in 4 steps.

01

You write to us

One email is enough. Roughly describe what you need — we'll get back to you within 24 hours.

02

We build a prototype

No workshop, no slides. We build something you can touch right away. 3–5 days.

03

You see, you decide

We show you the prototype. Right direction? Then we talk about scope and budget.

04

Go-live + Ember maintenance

Your solution goes live. From here you maintain it via chat — or we do it for you.

Ember — The glow that keeps burning

After handoff, maintaining your website is effortless.

You chat AI understands Code is changed Preview You approve Live
Tier 1

We maintain

You send change requests, we implement them. Classic agency model, AI-accelerated.

  • Changes via email or chat
  • Implementation within 24h
  • Preview before go-live

For clients who don't want to deal with tech

Tier 2

Chat maintenance

Your own access to the chat interface. Text, images, business hours — everything via chat.

  • Your own chat interface
  • Edit content yourself
  • Preview before go-live
  • Structural changes escalated

For digitally savvy clients without their own developer

Tier 3

Full control

Everything from chat maintenance, plus new pages, layouts and sections — directly via chat.

  • Everything from chat maintenance
  • Create new pages
  • Modify layouts
  • Maximum flexibility

For teams with their own marketing who want to iterate fast

Four promises.

No fine print.

Build first, present solution

We build first, then present. No discovery workshop, no slides — you see what you get.

The website is yours

Open-source stack, no lock-in. You can leave anytime. We earn your business every single month.

Transparent pricing

No hidden fees. You know the cost upfront. Maintenance costs cents per change.

One-click rollback

Every change is a Git commit. Don't like something? One click to revert.

What you won't
get from us.

We're honest about what we're not.

No discovery workshops. We build a prototype instead of painting slides.

No vendor lock-in. Open-source stack, your code on your server.

No CMS overhead. No WordPress, no Shopify — lean code, fast pages.

No hidden costs. You know the price upfront. Period.

No AI buzzwords. We don't say "revolution" — we show results.

No enterprise pricing. Fair prices for SMBs, not calculated for corporations.

Your website needs to do more
than look good.

The way people use the internet is fundamentally changing.

LLM-powered search

ChatGPT, Perplexity, Google AI Overviews — more and more people search via AI. Your website needs to show up there.

AI Agents

Autonomous AI agents will soon browse websites, book appointments, submit inquiries. Your presence needs to be machine-readable.

Voice & new interfaces

Voice assistants, wearables, AR — the browser is just one access point now. We build for all of them.

In days, not months

Our lean stack makes it possible: we integrate new access channels in days. The big platforms need months.

Squarespace, Wix, WordPress — too slow for this shift. Our stack is intentionally lean, so we can serve every new trend before your competition has even heard of it.

Good to know.

That depends on the scope, but you only pay after you've seen a working prototype. Most projects range between 2,000 and 8,000 EUR. Maintenance via Ember costs cents per change — no monthly fixed costs.
Ember is our digital maintenance system. You write in a chat what you want to change, the AI implements it, you see a preview and approve. Like a personal webmaster, but instant and at cents per change.
These platforms are too slow for the AI shift. If a new interface comes tomorrow (Voice, Agents, AR), they need months for a plugin. Our stack is lean enough to react in days. Plus: your code belongs to you, not to a platform.
Yes. Hosting on European servers, no tracking, no cookies without consent. Ember uses AI APIs in a GDPR-compliant way — no customer data flows into training.
You get all your code. Open source, no lock-in. Any developer can pick up where we left off. We earn your business every month — not through dependency.

Let's talk.

Limited capacity, personal attention. Write to us — we'll get back to you within 24 hours.
