Inventio Group was born from the will of its founders to inject creativity, innovation and passion into public conferences and events, but also to develop a real and beneficial communication between citizens and elected officials, contractors and employees. For many years in and around the EU institutions, both co-founders have organised larged events and worked on participatory and deliberative devices as well as political communication.

In 2014, they both left the EU institutions and founded Inventio Group.
