Université Paris-Saclay and its partners at Viva Technology 2024

Innovation Article published on 06 May 2024 , Updated on 17 May 2024

From 22 to 25 May, Europe's leading start-up and tech event, Viva Technology, will return to Paris Expo - Porte de Versailles. Come and meet Université Paris-Saclay on stand B56 and find out all about the projects and start-ups from its ecosystem.

A major international event, Viva Technology brings together innovation and transformations which tackle the major societal, environmental, economic and human challenges of today and tomorrow.

Université Paris-Saclay is the only university in France to have its own stand at the event. It will be joined on stand B56 by its four Grandes Écoles and founding members of the university - AgroParisTech, CentraleSupélec, ENS Paris-Saclay and Institut d'Optique Graduate School, two national research organisations - Inria and ONERA, as well as the Paris-Saclay Technology Transfer Acceleration Office (SATT), the IncubAlliance incubator and the DATAIA artificial intelligence research institute. Several start-ups from the region and the Paris-Saclay university community will also be present on the stand.

At the heart of a technology cluster that accounts for 15% of French R&D, Université Paris-Saclay has chosen to make innovation a central part of its strategy, placing it on the same level as research and education and fully incorporating it into its missions.

In July 2023, the university was awarded the official University Innovation Cluster label (PUI - pôle universitaire d’innovation), as part of the government’s France 2030 investment plan. The Université Paris-Saclay Innovation Cluster brings together 13 key players from the area’s innovation ecosystem and 15 partners. The Viva Technology event will be a key opportunity to position the PUI in the region and raise its international profile.

Projects/start-ups featuring on the university's stand:
