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.
What we appreciate is that it’s built with democracy in mind and therefore democracy is a big focus. Democratic principles such as accountability, equality and transparency are in the core of the design.

Almost every participatory process that has come to our table, we have been able to solve it using Decidim's business rules. As a tool, it is a very strong one. However, the part that seems strongest and most important to us is its community, both developers and those who use it for participatory processes. Coexisting with them has made us appreciate the challenges involved in implementing participatory democracy in the real world.

Part of what makes Decidim so powerful is that it adds a level of abstraction to the work separating out the steps of a process and the activities associated with the process. That’s part of the information architecture, so that not only you are saying what is happening at each step but different parts of Decidim behave differently depending on when you are doing or depending on what step in the process you are in. The fact that that’s customizable really allows Decidim to be moulded to how we are doing our work and not our work to be moulded.
