02 / 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.
- 01
Discovery workshop
A working session on site with your operations team. We walk every workflow with the person who lives in it and record where work stalls.
- 02
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.
- 03
Architecture & roadmap
Independent advice on what to build, buy or leave alone, and in which order, so each phase ships something usable in production.
A recent concept
For a Luxembourg property-management group: seven business processes mapped end to end, seven bottlenecks individually costed, a thirty-page executive concept.
Eligible for the SME Packages: the state reimburses up to 70% of eligible costs. Eligibility is decided at the pre-analysis.
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.
