Who’s behind the platform?
Metadecidim is the community that collaborates in the design of the platform and the development of the project. Together we design and create new features and report bugs for continuous improvement of the platform.
The Decidim Free Software Association is a democratic association for the governance of the Decidim community.
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.
