EntrInnO is a project that focused on addressing the need for optimizing the development of entrepreneurship and innovation in Europe. Its main focus is to enhance the skills of young EU citizens, a crucial population of a progressive, entrepreneurial and market-based economy and society. For that purpose, an interactive online game was developed, which is accessible online and offline, and can be adapted to fit various contexts. The focus of the online game and mobile app are to help youth develop entrepreneurial skills.
