Events Conferences Sébastien Chaillou - Centenary Conference Keynote Speaker We're thrilled to be welcoming Sébastien Chaillou, President of the International Co-operative Alliance Youth Network, to speak as at our Centenary Conference. He'll take to the stage as part of our dedicated youth day on Tuesday 26 November. About Sébastien Sébastien is 31 years old and lives in Paris (France). He became passionate about social change and concrete action when he joined a student union in university: he have ever since been driven by the will to help people answer their immediate needs but also contribute to the transformation of our society. He joined the Solidarité Etudiante initiative in 2013 to create a cooperative focused on helping students self-organize and manage their own services on campus, rising to Chief Director. Sébastien is also involved in many projects to promote cooperation and represent young cooperators, co-founding the Young European Cooperators Network. He also became the first elected representative of young cooperators in the ICA back in 2017.
