Zello is an application startup located in Austin, Texas, behind the creation of Zello applications. The applications are push-to-talk (PTT) walkie-talkie for consumers and business and available for Android, iOS, Blackberry, Windows Phone, Windows PC, rugged mobile devices and two-way radios. Zello is free while the Zello@Work application is free for up to 5 users.[1]

Company history[edit]

Alexey Gavrilov developed the product originally called Loudtalks which was announced at the TechCrunch 40 Mobile and Communications Conference on September 17, 2007.[2] Zello acquired the Loudtalks technology, rebranded, moved the development team to Austin, added aps and announced June 20, 2012.[3] Bill Moore is the CEO and Gavrilov is CTO. Moore founded and was CEO of TuneIn where Gavrilov and his team created popular TuneIn applications.


Zello acts as a replacement for traditional two-way radios, offering additional features such as history, replay last message, notifications and Bluetooth device support. It works over 2G, 4G, 3G and GPRS/EDGE networks.[4] Zello is "a direct messaging service that allows members to communicate freely either privately with individuals or over open channels that can support hundreds of thousands of users," said U.S. Senator Ted Cruz.[5] It allows people to use cell phones and computers all around the world like walkie-talkies.[6]

Zello users can create channels and give control to other Zello users to become moderators. New York Times' technology columnist David Pogue describes Zello's channels, "Like most of the best applications, Zello lets you create groups so that you can carry on something like a party-line phone call among a handful—or hundreds—of friends or collaborators."[7]

Once a channel is created, channels can appear on the "Trending" list and creators can assign additional moderators to keep their created channels safe. Though available for Android, iOS, Windows Phone and Blackberry, Zello can also be accessed from a Windows PC computer with the Zello for Windows PC.[7]


Zello made the news in June 2013 when Turkish protesters used it to circumvent government censors.[8] As a result, Zello was the top most downloaded application in Turkey during the first week of June 2013.[9]

In February 2014, it was blocked by CANTV in Venezuela. Zello issued workarounds and patches to overcome the blocks to support approximately 600,000 Venezuelans who have downloaded the application to communicate with each other amidst protests.[10] It "has been one of the most downloaded applications in Ukraine and Venezuela."[11]
