CliPeDia was founded in 2015 by Marc Haelterman, professor at ULB’s École Polytechnique de Bruxelles and the Solvay Brussels School. The platform already reaches a wide community: more than 10 million views and over 125,000 subscribers. The Helios-funded programme takes CliPeDia from a popular set of lessons to a complete, structured curriculum by September 2029.

The production team. Four teachers anchored the first phase: Jean Servais (physics and maths), Orianne Bastin (chemistry), Léni Jodaitis (chemistry and biology), and Loïc Haelterman (biology, FNRS-ULB). Three more are in their trial period: Jean Kimus (physics), Lucile Vanderschaele (statistics), and Natacha Englebert (mathematics for the first and second degrees of secondary school). Coordination passed after four months from Henri Haelterman to Elisabeth Gruwé, the ASBL’s secretary-treasurer.

Interactive learning. Beyond video, CliPeDia is developing the platform to turn lessons into interactive learning experiences, including a collaboration with Joseph Braginsky, founder of DidaGO, an AI that generates customisable interactive lessons aligned with school programmes. The project was presented to the cabinet of Education Minister Valérie Glatigny of the French Community of Belgium on 13 April 2026 in the hope of additional funding.
