Votizen is a consumer technology company that is developing an online network of voters in the United States. Based in Mountain View, California, the site allows its members, which it calls "Votizens", to learn about issues and elections, and take collective action with other committed voters through social media. Votizen verifies that each voice belongs to a real voter in the real world. As of 2012, Votizen has mapped out over a million connections between voters on Votizen. Votizen was founded by David Binetti, Jason Putorti, and Matt Snider in March 2010. The catalyst for Votizens growth sprung from the success of a Twitter campaign in 2010 in support of the Startup Visa, where thousands of people tweeted their support of the bill and Votizen delivered the messages to the appropriate people. In September 2010 Votizen announced it had raised $1.5 million in funding led by Peter Thiel and Sean Parker of Founders Fund with participating investors including 500 Startups, David Cowan, Keith Rabois, Ron Conway, Mark Goines, Founder Collective, Felicis Ventures, PivotNorth, Steve Blank, Eric Ries, Shervin Pishevar, and Tom Shields. On September 14, 2011, Votizen conducted the first "virtual" precinct walk with San Franciscans for Jobs and Good Government, a committee supporting San Francisco mayoral candidate Ed Lee. Votizen was attempting to bring the door-to-door walking in support of candidates to the 21st century by allowing registered voters to express their support for Ed Lee and ask their friends to pledge to vote for Ed Lee. Votizen plans to have their virtual precinct walks boost voter participation and play a big role in the 2012 elections. Randi Zuckerberg, former marketing director at Facebook, spoke about Votizens virtual precinct walk and believed "The virtual precinct walk has the potential to turn conventional campaigning on its head and inspire more people to vote."
