All participants worked in a team for the whole week-end. Each team have created a prototype on a specific challenge. This year the purpose was to address the first prototype of a mobile app to potential users that would like to find a specific important product missing on the market due to a future pandemic. Participants were told to focus on the product they wanted or to choose by default hand sanitizer. The event did not focus on brainstorming about the product but on creating the app in 2 full days so most of the prototypes have been made for hand sanitizer.
