Prediki is a peer-to-peer platform for opinion research and collective intelligence built on prediction market methodology. Developed by DOD member Hubertus Hofkirchner, it was presented at the [2017 Designing Open Democracy event](../blog/posts/2017-08-21-podcast.md) alongside Nicolas Gruen's talk on isegoria and citizens' juries.

The two presentations are complementary: Gruen's argument concerns *who* should decide (randomly selected citizens), while Prediki addresses *how* to aggregate and surface considered opinion at scale.

See the [Democracy Landscape entry](../organisations/prediki.md) for a full description of how the platform works.
