Demonstrators in countries like Venezuela are using a smartphone app to organize. Zello was developed in Texas. CEO Bill Moore says it functions something like a walkie-talkie and its use is growing rapidly.
“When we started, we certainly didn't suspect we were building an appl for protesters,” Moore says, “but it has become clear it is a good tool for them."
There are 53 million users worldwide so far, and that number is growing.
“It was the most-popular app -- out of Facebook, Twitter, everything -- during the Egypt uprising,” he says. “Then, over the past week or so, it's number one app in Venezuela and it's also the number one app in Ukraine.”
Zello has some users in the U.S., but many more overseas.
