The recent COVID-19 era demonstrated the need for seamless education, accessible under most challenging circumstances. It was revealed that while the technologies for facing these challenges exist, more work is needed to adapt these in modern education – a task that requires significant collaborative effort from academia and the rapidly developing Educational Technology Sector (EdTech) in order to involve best practices and validate novel products and services for the real world classroom use. For various reasons, this collaboration has been meagre so far. The goal of the EdTech Talents project is to strengthen academia/non-academia cooperation and reinforce the EdTech innovation ecosystems of Estonia, Hungary and Serbia by conducting a long-term knowledge transfer process for (a) the researchers and their support staff of these widening countries to learn from the EdTech spin-offs and consulting companies of Austria, Germany and Spain; and (b) the researchers of these advanced countries to share their relevant intellectual capital with the EdTech start-ups of these widening countries. During this process, knowledge transfer is supported via dedicated mentoring and training that aim at establishing continuous and more impactful flow of innovation, ideas, knowledge, know-how and relevant services among all involved, corresponding with the scope of ERA Policy Agenda and ERA Talents call for cross-sectoral talent circulation and academia-business collaboration, with the focus on widening countries.
