"We suffer under a lack of public space. Its 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."

"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."

"Thanks to Decidim, in Barcelona we have managed to co-produce a strategic city plan together with the citizens. In 2016 we inaugurated the Municipal Action Plan in the form of a participatory process through Decidim Barcelona. Currently, this plan includes almost 7 thousand citizen proposals. One of the advantages of using this platform is that you can monitor at all times the state of implementation of the approved proposals."
