D21

D21, formerly Democracy 2.1, is a voting system allowing participants to choose multiple options as well as cast negative votes for the unfavorable in order to reflect a wider range of preferences compared to single-vote polls. In doing so, D21 results illuminate both points of consensus and points of controversy.

Results from votes can be segmented by gender, age, neighborhood and profession, information that is gathered from anonymous and voluntary contributors. Additionally, the platform offers data visualization, map analysis, and proposal functionalities.

Other polling system features include: brand customization, voter verification (create verified voter lists and invite participants by e-mail or SMS), online and paper ballots.

Frustrated by the endemic corruption and electoral dysfunction of his native Czech Republic, anti-corruption activist, mathematician, and philanthropist, Karel Janeček, began developing the new voting system in 2012. D21 was beta tested in October 2013.

The D21 voting platform has been used in diverse project contexts. Among the many examples are: participatory budgeting in cities, stakeholder voting at organization meetings, staff engagement for businesses, and parent participation in school decisions affecting their children.

The company is headquartered in Prague, Czech Republic, but also has team members on the ground in New York, Paris, Tunis, Beijing, and Bangalore.
