Today, we are thrilled to announce that Probabl has successfully closed a pivotal community funding...
Just one year ago, we announced our mission: to empower the future of data science by transforming open source excellence into sustainable industrial infrastructure.
Today, that mission takes a giant leap forward.
Probabl — the official and exclusive operator of scikit-learn, the world’s most widely used machine learning library (over 2.5 billion downloads) — has raised €13 million in seed funding, co-led by Serena and Capital Fund Management (CFM), following earlier support from Apertu Capital, with renewed support from Mozilla Ventures and French Tech Souveraineté, part of the France 2030 investment plan.
This round brings Probabl’s total seed financing to €18.5 million, marking one of the largest open-source software seed round ever raised in Europe.
From Open Source Roots to Global Ambition
At the heart of France’s national AI strategy (SNIA – France 2030), Inria and Probabl joined forces in 2023 to transform the scientific foundation of scikit-learn into a new generation of open and sovereign data science infrastructure.
Probabl’s mission is simple yet profound:
"Turn artisanal data science into industrial-grade infrastructure."
This seed round gives us the firepower to project Probabl onto the international stage. We’re building a unique force in open source to help companies truly own their data science — transforming machine learning from a black box into a transparent, reliable, and value-generating engine.
Skore: Bringing Data Science to Prime Time
Probabl’s upcoming product, Skore, bridges the gap between data science and AI performance.
Rooted in the rigor of machine learning and the trust earned by scikit-learn, Skore helps enterprises translate AI investments into measurable performance — far beyond the GenAI hype.
“With Probabl, we aim to strengthen scikit-learn’s open-source and scientific foundation,” explains Gaël Varoquaux, co-founder of scikit-learn and Probabl. “Our goal is to empower businesses to leverage their data through machine learning that is simple, responsible, reproducible, and sustainable.”
Skore is now entering its final stages before launch, with several corporate design partners already on board — and early enterprise users validating its promise.
They say it best

Growing Fast: Team, Product, and Purpose
Over the past year, Probabl’s team has tripled, now counting more than 30 engineers, researchers, and product specialists across Paris, Saclay, Berlin, and Sophia-Antipolis.
The company has already signed its first enterprise clients, strengthened the scikit-learn core team, and built a fast-growing ecosystem around open, reliable data science.
The next chapter is clear:
-
Accelerate Skore’s adoption across industries
-
Expand commercial services around scikit-learn and related open-source tools
-
Build Europe’s open-source AI powerhouse
