In this paper, we introduce a new categorisation for innovation tools, which we employed to structure the Toolbox for Open Societal Innovation (TosiT) – a database of innovation software and services, which was developed in the international research project eSociety Bodensee 2020. The suggested categories are designed with the user in mind to make the toolbox easily accessible for interested actors. Open Societal Innovation (OSI) is a concept that combines the notions of open innovation and social innovation, in order to foster innovation from the society for the society.
