The aim of the Social innovation Hackathon event is to bridge people from different backgrounds and explore how IT can help deliver social innovations that can have a global impact. The event features social entrepreneurs, non-governmental organisations, companies that are working towards social innovation, academics, students, and social groups facing challenges. NTNU organises this seminar connected to the EU-project «SOCRATIC» in Horizon 2020 (www.socratic.eu). The main goal of the project is to provide citizens and organisations a collaborative space where they can identify innovative solutions to achieve the Sustainable Development Goals set by the UN. The event was organised by Letizia Jaccheri, Professor and Head of Department of Computer and Information Science, NTNU.
