Why we exist

stat4decision was founded in 2012 by Emmanuel Jakobowicz, PhD with a simple observation: organisations had valuable data but lacked the expertise to use it — without jargon, without over-engineered solutions, with a genuine focus on results.

Over 12 years we've worked with 200+ organisations — from CAC 40 companies to public research institutions — on data science, machine learning, AI and statistical analysis projects.

Our conviction hasn't changed: the best data solution is one your team understands, maintains and extends without us. That's why skills transfer is built into every engagement — not sold as an add-on.

Open source only
No vendor lock-in, ever
Python, R, Mistral AI, Hugging Face. Every tool we use is inspectable, forkable and replaceable. Your models and code are yours — no runtime licence needed to run them.
Practitioners, not theorists
We debug production, then teach
Every trainer and consultant is active on client projects. The gap between theory and practice closes when the person teaching you debugged the same issue last week.

Emmanuel Jakobowicz
Founder & Data Scientist · PhD
"Data only has value if it helps someone make a better decision. Everything else is noise."

With a PhD and over 15 years of experience in data-driven projects and research, Emmanuel founded stat4decision in 2012 to bridge the gap between academic rigour and operational delivery. He has led data science and AI projects across banking, energy, healthcare, retail and public research.

He teaches and consults on data science, machine learning and generative AI — believing that the best solutions are the ones teams can own, understand and extend independently.

What we believe

Four principles that shape every project and every training session.

Pragmatism
A model that isn't deployed is worth nothing
We measure every engagement by what's in production, not what's in a slide deck. Framing, prototyping and shipping to production are part of every mandate.
Transparency
We explain what we build and why
Open-source code, documented models, reproducible environments. At the end of every engagement, your team understands the system and can maintain it without us.
Sovereignty
Your data stays on your infrastructure
We deploy on-premise or in your private cloud. Sensitive data never touches a third-party API. We use open LLMs — no dependency on proprietary model providers.
Partnership
We work with you, not for you
The best outcome is a client who doesn't need us for the basics — and comes back for the next challenge. Skills transfer is built into every contract.

15+ practitioners across 6 domains

Every expert at stat4decision consults and trains simultaneously — no career academics, no separated tracks.
