Democracy does not just mean that citizens can vote every few years. Digitisation can be used to bring together administrations, policymakers companies and citizens in decision-making processes. With “opendoors”, the Zebralog agency developed a free open source platform for participation that can be installed especially easily in the Microsoft Azure Cloud. For example, politicians or companies can ask questions, interest groups can collect discussion topics, and all of the participants can carry out a dialogue - transparently and without technical obstacles.
