The Revolution Will Be Texted Celly builds mobile social networks that can be accessed by any cell phone, unlocking possibilities for group communication during social and political protests.

During the December 2011 Occupy protests in Portland, Ore., someone projected the Batman "bat signal" over the crowds onto a building downtown. Then, one night, the signal was replaced by slogans such as "End the Federal Reserve!" and "The revolution will not be privatized!" Like the protests themselves, the messages didn't originate from any one central source. The only clue was that they came from anonymous protesters who were using a revolutionary new social network called Celly.

Founded in April 2011 in Portland by Greg Passmore and Russell Okamoto, Celly builds mobile social networks of all sizes, both public and private, that can be accessed by any cell phone with SMS and via a web browser, e-mail and the company's iPhone and Android apps. "Group communication unlocks so many possibilities across the socioeconomic and political spectrums," Okamoto says. "We wanted to build the simplest tool that we could, that would have the broadest, deepest impact on the most people."
