From an on-premise stack for regulated firms to the fixed €750 audit. Starting prices below — I name the exact figure after a short call: fixed scope, fixed price, no surprises.

On-Premise AI Stack
Pricingon request
8 — 16 weeks
Self-hosted AI for regulated practices: Docker, local LLMs, RAG over internal data. No data leaves your network. Quarterly updates, rolled out in stages. Currently two production pilots with tax advisors in Aachen.
A fit when
—Tax advisors, law firms, medical practices, regulated SMEs.
—Client data must never touch a US cloud, under any circumstances.
—An existing server room — or the willingness to build one.
Wire AI capability into existing software or workflows — including harness engineering: designing and building agent harnesses, tool and skill design, orchestration, context engineering, evals. Cloud, hybrid or on-prem — whatever fits. Document classification, RAG, chatbots, AI-in-the-loop automation. The source code is yours from day one.
A fit when
—You're building an agent or LLM system and need someone who has built harnesses before.
—You know which task AI should take on in your business.
—Existing tools / databases / internal APIs are in place.
Before you spend on AI: I look at your processes and tools and deliver a short, honest report — the 3–5 places where AI saves time or money, what I'd build there and roughly what it costs. Fixed price, fixed deliverable. Decide on a build within 60 days and the audit fee is credited in full.
A fit when
—You want to know where AI really helps — before you invest.
—You need a basis for a decision, not sales slides.
Architecture reviews, build-or-buy calls, vendor selection, a second opinion on a build in progress. The hourly rate covers all consulting. The first call is free — after that €160/h (2h minimum). Notes and a written summary are included. Need more? Step up to the audit (€750, creditable) or a build.
A fit when
—An internal team is mid-build and stuck.
—You're about to sign a contract you don't fully understand.
From a lean CMS website (from €1,500) through a business site with SEO (from €2,500) to custom web apps, dashboards and shops. Fast, because a team of AI agents helps build it; solid, because an experienced developer stays accountable. Ongoing operation (Care + Hosting) optional from €65/month, all from one hand.
A fit when
—A company presence, internal tool or client portal — built properly, not from a template kit.
—You want one point of contact for build, hosting and maintenance.
Write a paragraph about what you want to ship. I'll tell you honestly which service fits — or whether you need someone else. With real process pain, the €750 audit is the best entry point: it delivers the map and is credited in full toward a build.
