Open Source, Open Data, Open Weights
Open Source has shown that removing barriers to learning, using, sharing, and improving software is beneficial to all.
By applying these same principles to artificial intelligence — autonomy, transparency, frictionless reuse, and collective improvement — we can extend these benefits to everyone: developers, deployers, and users.
probabl.ai was born out of French scientific excellence at INRIA and builds upon the legacy of the iconic scikit-learn project.
Our mission: to set the highest standards for Open Source in data science.
Through our commercial activities (certifications, products, consulting), we accelerate the dissemination of our innovations into the real economy.

👨🍳 My Work Philosophy
Domains are languages. I choose to learn yours — and share mine.
🤝 A partner, not a consultant
You don’t need another slide deck or generic dashboard.
You need someone who co-builds with you — from day one to delivery — and then empowers you with clarity and systems you fully understand.
