Why Rennes is increasingly attracting ambitious companies
Rennes does not settle for playing a secondary role in Brittany. Here, development and innovation intertwine concretely and set the pace. As the regional capital, the city is transforming into a true laboratory for industrial and digital projects. This dynamism is illustrated by the density of its 40,200 production establishments recorded in 2020. Nothing is left to chance: everything relies on a qualified workforce, a solid academic tradition, and a network of public and private actors ready to collaborate.
The local environment creates conditions for continuous growth. Rennes Métropole proudly champions ecological transition, with nearly one-fifth of farms acting in favor of organic practices, and prioritizes concrete sustainability policies. Business zones benefit from well-oiled logistics thanks to connections with Paris and Caen. The result: digital, health, and agri-food sectors show sustained growth, making Brittany a national pillar of digital technology and a European reference in agri-food.
