Who’s behind the platform?

The Decidim Free Software Association is a democratic association for the governance of the Decidim community.
Was wir schätzen ist, dass es unter dem Gesichtspunkt der Demokratie aufgebaut ist und daher die Demokratie ein großes Anliegen ist. Demokratische Grundsätze wie Rechenschaftspflicht, Gleichheit und Transparenz stehen im Mittelpunkt des Entwurfs.

We suffer under a lack of public space. It's particularly important that we reclaim these public spaces for us. Open platforms such as Decidim do exactly that. Is not only that is open source so other people can fork it, reuse it and build a process. It also has these values that we want to reflect in our society encoded in the way it's designed.
