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.
Pràcticament cada procés participatiu que ens ha arribat, l'hem pogut resoldre utilitzant les regles de negoci de Decidim. És una eina molt potent. No obstant això, la part que ens sembla més forta i important és la seva comunitat, tant de desenvolupadores com d'aquelles persones que la utilitzen per a processos participatius. Conviure amb aquesta comunitat ens ha fet dimensionar els desafiaments que comporta implementar la democràcia participativa en el món real.

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.

Gràcies a Decidim, hem aconseguit a Barcelona co-produir un pla estratègic de ciutat conjuntament amb la ciutadania. En el 2016 inaugurem el Pla d'Acció Municipal en forma de procés participatiu a través de Decidim Barcelona. Actualment aquest pla recull gairebé 7 mil propostes ciutadanes. Una dels avantatges d'utilitzar aquesta plataforma és que pots seguir en tot moment l'estat d'implementació de les propostes acceptades.
