A year ago or so I connected with the MiVote folks, who are also connected to the Horizon State folks; both of those groups are working on “civic tech” type interventions. They have both been very successful so far. MiVote seems to be focused on reducing corruption by getting the money out of the system. They have done a lot of work on processes for developing sound policy as well. And Horizon State is working on the blockchain angle.
