Urban Data Community

Come into exchange with our network to actively develop existing data-based solutions for cities & municipalities, to adopt them and to carry them out on a broad scale!


Brown Bag Lunches

Once a month, we host Brown Bag Lunches for municipalities & municipal enterprises to provide information on current data-driven solutions and their added value. Only available in German for now.



Square is the Smart City portal that guides municipalities & municipal enterprises from local challenges to the data-driven solutions and provides relevant products, implementations, and practical tips & hints.
