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.

The process started in October 2019 at the European Commission’s DG Communication and eDemocracy unit at the Joint Research Centre, the European Commission's science and knowledge service. An analysis of the needs of the Conference and which tools fit those, lead to choosing the open source tool Decidim for its technical maturity, broad community and adaptability.

With the implementation of Decidim in Som Energia we have generated a kinder space for participation. We released the tool in 2018, hosting the General Assembly of the Cooperative and months later we debated the Image Redesign and collaborative development of the School of Som Energia, among other participatory processes. In a few months, more than 3,500 participant people have registered, 5 participatory processes, 3 assemblies operating and more than 1,300 votes in the last General Assembly vote.
