Wanting AI and keeping your data – it works.
For public authorities, banks, healthcare and every mid-sized company whose data must not leave the building.
Open models run on your own hardware today – from a single laptop to the data centre. We show you how: as a feasibility workshop or project support. You get an honest picture of what works locally. And what doesn't (yet).
What can we do for you?
Feasibility workshop
Start small, evaluate honestly: we take one concrete process from your organisation and build a prototype together – with a local model, on your hardware. Afterwards you'll know whether the big step is worth it:- Selecting a suitable use case
- Model selection and hardware sizing
- Prototype: a working workflow or RAG pipeline
- Measuring against your real data
- Honest assessment: quality, costs, limits
- Recommendation and roadmap
1 to 2 days
available at short notice on request – ideal as a first step
Project support
From prototype to production: we support you in building your AI infrastructure – architecture reviews, model evaluation, operations and hardening.We also stay available after a training: in regular office hours we answer questions from your day-to-day project work, within the budget you set.

Frequently asked questions
◢ Who is this offering for?
Organisations that want to use AI but whose data must not end up in third-party clouds: public authorities and administration, banks and insurers, healthcare, critical-infrastructure operators – and every SME whose data protection officer rightly asks questions. For getting started with Agentic Coding we also recommend our AI team training.
◢ Why work with us?
We build the solutions ourselves, publish our findings openly on the blog and measure results against your real use cases.
And we say where local models hit their limits today – we only promise what we can demonstrate.
◢ What does the consulting cost?
We offer the feasibility workshop at a fixed price, project support by effort within a budget you set. We clarify goal and scope in a free intro call, and you receive the quote within 24 hours.
◢ What are the prerequisites?
All engagements are remote by default. On-site sessions for workshops are available on request.
For workshops with local models, existing hardware is often enough – a model like Gemma 4 (12B) runs on laptops with 16 GB of memory. For project support we need access to your documentation and source control, via VPN if necessary.
◢ Isn't local much worse than ChatGPT & co.?
For some tasks, yes – for a surprising number, not any more: local models handle classification, summarisation, extraction and internal search reliably today. We show the difference live and measure it against your use cases – and where frontier quality is needed, we show hybrid approaches (non-critical tasks in the cloud, sensitive ones local).
◢ Who is the consultant?
The consulting is done by book author and Google Developer Expert (GDE) Johannes Hoppe. He works in regular client projects and passes on his practical knowledge directly.
