Circular Challenge, Citeo’s Open Innovation programme

With its 5 years experience, Circular Challenge Citeo has proven its ability to identify, support innovative and concrete solutions, both in France and abroad, and foster a real ecosystem of committed players

In 2021, Circular Challenge Citeo launches its 1 year accelerator programme. 

The accelerator programme will help circular solutions to grow, scale and increase their impact for the benefit of the whole ecosystem involved in the transition towards a circular economy. 



Open Innovation combines "thinking" and "doing" to build together: with companies, local authorities, operators, manufacturers, associations, designers and entrepreneurs. Innovation is one of the drivers of a circular economy at the service of a successful ecological transition. Sharing and collaboration are the keys to its success.

Circular Challenge's actions are routed in open innovation. Co-construction and interdisciplinarity are the main features of a range of projects and initiatives which, thanks to design methodologies, offer concrete and immediate solutions.

Based on a broad ecosystem of entrepreneurs, innovators, investors, companies, manufacturers and communities, Open Innovation aims to enable the acceleration and deployment of relevant solutions and thereby contribute to the transition to a circular economy.
