The Danube Cup is an international network of universities along the Danube to enhance entrepreneurship education and support student startups. By bringing together diverse actors from a variety of countries, the aim is to learn from best practices and diffuse important research across national borders. The second research-focused conference organized by the network in Belgrade, Serbia was held in late November 2023. The Changemaker Marketday stood as a shining best practice example of early entrepreneurship education, bringing economic topics to Austrian primary schools.
