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.

Platforma digitală Decide Meeartha a fost o oportunitate care a fost mai deschisă ca niciodată înainte de mecanismele de participare a cetățenilor la elaborarea Planului de Dezvoltare Municipală al MeThererida 2018-2021. Am avut peste 3.000 de interacţiuni între cetăţeni, inclusiv propuneri, comentarii, sugestii și sprijin pentru obținerea celui mai mare consens posibil cu privire la ce este mai bine pentru orașul nostru. Fără îndoială, platforma Decide Me·rida va continua să fie aliatul nostru pentru a transforma Meτ rida într-o societate din ce în ce mai participativă.

The process started in October 2019 at the European Commission’s DG Communication and eDemocracy unit at the Joint Research Centre, the European Commission's science and knowledge service. An analysis of the needs of the Conference and which tools fit those, lead to choosing the open source tool Decidim for its technical maturity, broad community and adaptability.
