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.
Odată cu punerea în aplicare a Decidim în Som Energia am generat un spaţiu mai bun pentru participare. Am lansat instrumentul în 2018, găzduirea Adunării Generale a Cooperativei şi câteva luni mai târziu am dezbătut despre Reproiectarea imaginilor şi dezvoltarea colaborativă a Şcolii Som Energia, printre alte procese participative. În câteva luni, au fost înregistrate peste 3 500 de participanți și 5 procese participative; 3 adunări funcţionează şi peste 1 300 de voturi în cadrul ultimului vot al Adunării Generale.

Aproape fiecare proces participativ care a ajuns la masa noastră, am reuşit să îl rezolvăm folosind regulile de afaceri ale Decidim. Ca instrument, este unul foarte puternic. Cu toate acestea, partea care ni se pare cea mai puternică şi cea mai importantă este comunitatea sa, atât dezvoltatorii, cât şi cei care o folosesc pentru procesele participative. Coexistenţa cu acestea ne-a făcut să apreciem provocările pe care le implică punerea în aplicare a democraţiei participative în lumea reală.

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.
