How we work

Clear, fast, no bullshit.

  1. Conversation

    Video call or meeting. You explain your business and what you need. Free and no commitment.

  2. Concept & quote

    Within a few days you receive a clear proposal with scope, timeline and fixed price.

  3. Development

    We build your solution. You get regular intermediate versions to test — no surprises at the end.

  4. Launch & support

    We ship your solution. Then ongoing support, updates and improvements if desired.

▸ WHY // 03

What sets us apart

One point of contact

You speak directly with the developer building your solution. No account managers, no email ping-pong, no communication losses.

Fixed price, not hourly

We agree on a fixed price before the project starts. You know exactly what you pay — no nasty surprises at the end.

Real code, no plugins

We build custom solutions in PHP, JavaScript, and Python. You're not locked into WordPress plugins or builder systems.

AI expertise

We work daily with Claude (Anthropic) and GPT-4. We know how to deploy these models productively and cost-effectively.

Portrait of Marc Kreitz, founder of Central Intelligence Luxembourg
Marc Kreitz Founder · Developer · AI Systems Engineer

I've been building websites, databases, and automations in Luxembourg for over 20 years. What started with individual projects grew over time into an entire network of digital tools — valuation calculators, client portals, AI chatbots, CRM integrations. All built in-house, all running in production.

With Central Intelligence, I now offer this experience to other companies. No team, no overhead, no excuses — just direct contact with the person actually building your solution.

Frequently asked questions

Who is behind Central Intelligence?
Central Intelligence is a project by Marc Kreitz, founder of iSOLUTIONS S.à r.l. Over the last 20 years, Marc has built and maintained more than 15 web platforms in Luxembourg — from simple contact forms to complete CRM systems with AI integration.
How long does a website project take?
A typical business website with CMS and multilingual support takes 3 to 6 weeks. More complex projects with database, client portal, or AI integration need 6 to 12 weeks.
How much does an AI chatbot for my website cost?
A basic chatbot with Claude or GPT-4 starts around €3,500. A complete sales bot with lead capture, appointment booking, and CRM integration costs €8,000 to €15,000 depending on complexity.
Can you optimize my existing website?
Yes. We analyze existing sites for performance, SEO, and functionality, then propose targeted improvements — or develop a completely new solution if that makes more sense.
Do you only work in Luxembourg?
Luxembourg is our home market, but we work remotely across Europe. Working with clients in Germany, France, Belgium, or Switzerland is no problem at all.
What happens after launch?
We provide ongoing support: updates, security, performance monitoring, and further development. All flexible through a maintenance contract or on-demand.
