POLIS was created in the USA and its core open-source software is implemented on the original POLIS website. It has been used in Taiwan since 2012, which has helped to change several laws in Taiwan.
In 2018 the Computational Democracy Project was founded as a non-profit continuation of POLIS open source work and the mission behind it. Sustensis and Consensus are grateful for making this software available to a wider community.
Here are some links to examples showing how and where POLIS has been used world-wide.
