DemocracyOS - free code (MIT) created by the founders of the Net Party in Argentina. Uses blockchain technology inspired by BitCoin to certify decisions. Translated into 5+ languages.
Votorola - "...an experimental technology for the public guidance of electoral systems, executive offices, legislatures, and other decision systems. Uniquely it combines the devices of recombinant text, transitive voting, and vote pipes to build a maximum of personal freedom into its facilities. The main facilities are tree-form, decision guideways. Votorola deploys the leafward edges of these in support of the public sphere, where they provide a purpose and outlet for rational discourse."
GroupMindExpress - Commercial and proprietary. "Your team’s collective intelligence is greater than the sum of its parts; help them align with strategic planning and organizational development tools from GroupMind™. Strategic planning, change management, and organizational development processes benefit from experienced consultants with software that leverages collective intelligence."
