01 / Workshops & consulting
Start with a workshop. Leave with a plan.
Before anything is built, we sit down with the people who run your processes and work out where software and AI actually pay. You leave with arithmetic and a roadmap, not a pitch deck.

Executive concept
Each bottleneck costed from your own volumes, an architecture that sits on your existing systems, and a phased roadmap. A document you can take to a board.

/ Cybersecurity & NIS2
Security starts with people. NIS2 says so too.
Many incidents begin with an email, a password or a click. We train your teams and your management to recognise the risks, and help you see what NIS2 asks of your company.
- 01
Awareness training for your team
Phishing, passwords and multi-factor sign-in, handling data, reporting an incident: practical sessions for the people who receive the emails, in Luxembourgish, French, German or English.
- 02
Training for management
What NIS2 expects of the management body, and how to judge whether the measures in place are enough.
- 03
A first NIS2 check
Whether NIS2 is likely to concern you, directly or as a supplier, and which measures are still missing. A starting point, not a legal opinion.

NIS2 at a glance
- Art. 20(2)
- Members of the management body must follow cybersecurity training.
- Art. 21(2)(g)
- Basic cyber hygiene practices and cybersecurity training are among the required risk-management measures.
- Art. 21(2)(d)
- Supply-chain security is one of them too, so the question reaches suppliers.
Directive (EU) 2022/2555 (NIS2). We train and advise; we do not give legal advice. Whether NIS2 applies to a company is set by law.

AI at work
Sixteen seconds of an agent doing real work.
An email arrives, a document is read, a contract is checked, a person approves, the system is updated. This is what we build: AI that runs inside your operations, with people where it matters.

/ In motion
Built to move.
Real work, not just stills.
/ How engagements run
Large programmes. Delivered in phases.
Large systems are not built in one leap. Every phase has its own scope, budget and outcome, and the first one ends with something running in production.
- Phase 01
Discovery and architecture
On site with the people who run the processes. Bottlenecks costed, architecture and roadmap agreed.
- Phase 02
First release in production
One workflow, real users, real data, measured against where you started.
- Phase 03
Scale
More modules and workflows on the same foundation, each one cheaper than the last.
- Phase 04
Operate and evolve
Monitoring, maintenance and a team that stays accountable after launch.
/ The company
Built in Luxembourg. Close to your team.
We meet you in person, in Luxembourgish, French, German or English, and the people who scope your project are the people who build it.
