Common citizen tech

We advocate for open and accessible technology driven by the civic engagement

Who are we?

We are 🇵🇱-based group of change-makers who have been creating and exploring open-sourced solutions at the intersection of technology and civic engagement.

We're believe (and yes, sometimes we had to learn this the hard way) that no solution in social/civic/NGO-sphere can achieved alone, no less solely by tech enthusiasts, who often trap themselves in tech-solutionism thinking about cool & latest tech, while the underlying social problem remains unsolved.

That's why we're convinced that interdisciplinary collaboration and civic-participation are the keys to driving tangible impact. Interdisciplinary collaboration showcases a mosaic of skills and perspectives, while civic participation allows to approach civic challenges from multiple angles, sparking creativity and yielding comprehensive solutions.

We've developed and impacted a range of civic-tech projects and as we grow we continue our journey by establishing a foundation committed to advocating for open, inclusive and participation-driven public interest technology.
