We teach machines to work the way your business needs.
Rufa Labs is an AI lab from Luxembourg. We help companies use AI on their own terms: the right model for the job, trained on their data, running where their data already lives.
Your concerns are fair. Here is how we answer them.
Our data would leave for someone else’s cloud.
We run the models on your own servers or in a European cloud you choose. Your calls, documents and customers stay where they are.
Large general models can be hard to control.
A general model with a good prompt can still miss. We choose or train a model for the task and test it on your own examples first.
We tried RAG and it was not enough.
Retrieval alone rarely fits. We combine your data, fine-tuning, tools and checks, so answers are grounded, repeatable and right for your business.
We do not know where to start with AI.
You do not need to. We look at how your company works, start where AI clearly helps, train your team and stay with you after launch.
How we help
Machine learning experts
Train and evaluate speech and language models on real data.
Applied AI engineers
Turn models into products that work every day, not just in a demo.
Forward deployed AI engineers
Work inside your company, next to your team, until it runs.
Full-stack all-rounders
From the server room to the screen your customers use.
AI consultants
Find where AI pays off and plan the way there with you.
Our principles
Private by default
Your data, your servers, your rules. We never need to take your data away to help you.
A solution that fits, built to last
Secure, reliable and built to last. We would rather do it right than do it fast and fragile.
Measured, not marketed
We test on your own examples and show you the numbers. Anyone can try our models in the Rufa Arena.
