The Social Innovation Summit #SIS19 is a two day international event the on 20th and 21st September 2019 that addresses relevant topics in the context of social innovation and entrepreneurship. Focus topic this year: Shaping the Digital Future. We want to - create a common understanding of „social innovation“* to - drive collaboration accross sectors in order to - achieve collective impact**. This is not a usual conference about technology, digitalisation, startups, corporates or businesses of any kind. It is about using technologies, concepts, institutions and scalable solutions to create a better world. * We define social innovation as the development and proliferation of solutions to societal and environmental challenges (such as climate change, migration, digitalisation). **Collective impact occurs when organizations from different sectors agree to solve a specific social problem using a common agenda, aligning their efforts, and using common measures of success.
