Institutional support#

Scikit-learn is a community driven project. However, a number of public institutions and private entities have contributed and keep on contributing to its success and sustainability.

Since the inception of scikit-learn and for a good decade, Inria has been its main supporting pillar, as the stable employer of many core-maintainers and as the host for the scikit-learn consortium.

In 2023, Inria spun off Probabl as a mission driven company to take scikit-learn beyond a research lab. All of the scikit-learn core-maintainers employed by Inria have joined the spinoff as co-founders, most as full-time employees.

Today, Probabl employs the following core and non-core contributors: Adrin Jalali, Antoine Baker, Arturo Amor, François Goupil, Guillaume Lemaitre, Jérémie du Boisberranger, Loïc Estève, Olivier Grisel, Shruti Nath and Stefanie Senger, as well as Gaël Varoquaux.

The above financial commitments mean that Inria initially and now Probabl have been and are the main source of financial support for scikit-learn, completed by additional commitments detailed below. Cumulatively over a decade, these represent several millions of euros or dollars worth of financial participation.

Active financial participation (2026)#
