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.

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.

The Decide Mérida digital platform was an opportunity that opened as never before the mechanisms of citizen participation for the elaboration of the Municipal Development Plan of Mérida 2018-2021. We had more than 3,000 citizen interactions including proposals, comments, suggestions and support that achieving the highest consensus possible about what is best for our city. Undoubtedly, the Decide Mérida platform will continue to be our ally in making Mérida an increasingly participative society.
