Viber was founded by four Israeli partners: Talmon Marco, Igor Megzinik, Sani Maroli and Ofer Smocha, with Talmon Marco as its CEO.[10] Viber was initially launched for iPhone on December 2, 2010, in direct competition with Skype. A pre-release version for Android appeared in May 2011 but was restricted to 50,000 users; an unrestricted version was released on July 19, 2012. Viber for BlackBerry and Windows Phone devices was launched on May 8, 2012.[11] On reaching 90 million users on July 24, 2012, group messaging service and HD Voice engine were added to both Android and iPhone applications. Applications for Nokia's Series 40,[12] Symbian[13] and Samsung's Bada platform[14] were also announced on the same day.[15]

Initially, the voice calling feature was only available for iPhone and Android applications, with a promise that voice would be added in upcoming versions for Bada, Symbian and Windows Phone applications, with no mention of either Series 40 or Blackberry OS. The limitation seems to lie in the core of Blackberry OS and Series 40 which does not have easy support for VoIP apps.[16]

On September 22, 2012, HD quality phone calls and hold group-messaging sessions were made available for Windows Phone but only for Nokia users,[17] as part of exclusive partnership with Nokia.[18] Viber with voice was officially released for all Windows Phone 8 devices on April 2, 2013.[19]

In August 2013, Viber for Linux was released as a public beta[20] and in August 2014 a final version.[21] Initially, only 64-bit binaries were made available for download.

On February 13, 2014, Rakuten announced they had acquired Viber for $900 million.[22]


Viber Media is a Las Vegas and Cyprus-registered company[23][24] with its development centers in Belarus[25] and Israel.[26] The company was founded by Talmon Marco and Igor Megzinik, who are friends from the Israel Defense Forces.[27] The company is run from Israel, with much of its development outsourced to Belarus in order to lower labour-costs.[27]

Founded in 2010, the company is co-owned by its four Israeli founders: Talman Marco, Igor Megzinik, Sani Maroli and Ofer Smocha, who have each increased their investment by over 30 times on the startup's $900 million sale to Rakuten.[10]

Marco and Megzinik are also co-founders of the P2P media and file-sharing client iMesh.[28]

The company originally didn't generate revenues, but announced it would start generating revenues in 2013 via a "sticker store". The company is funded by individual investors, who Marco has described as "friends and family".[29] As of May 2013, $20M had been invested in the company.[30]

Features & functionality

The actual functionality varies from platform to platform with iOS and Android being the first to receive new features. Viber includes text, picture and video messaging across all platforms, with voice calling available only to iPhone, Android and Microsoft's Windows Phone although HD voice is planned for Windows Phone 8.[31] The application's user interface includes tab bar on the bottom giving access to messages, recent calls, contact, the keypad and a button for accessing more options. Upon installation, it creates a user account using one's phone number as username. Viber synchronizes with the phone's address book, so users do not need to add contacts in a separate book. Since all users are registered with their phone number, the software returns all Viber users among one's contacts. The newest version of Viber (Version 2.3) has added smileys and other default images.

Viber is also now available on Windows and Mac OS X.

As of December 2013, Viber officially launched Viber Out, a feature that provides users the option to call mobile and landline numbers; thus Viber users can call people not using a Viber app. Viber Out was originally released in November only to help Typhoon Haiyan victims in the Philippines connect with their loved ones. To use the new feature, users have to visit the "More" tab and choose Viber Out. No update is needed for the feature.[32]

Languages and localization

Viber is currently available in 30 languages and locales, including: Albanian, Arabic, Simplified Chinese, Traditional Chinese, English, French, German, Greek, Hebrew, Italian, Japanese, Korean, Nepali, Persian, Portuguese, Russian, Spanish, Swedish, Ukrainian, and Urdu.[5]


Concerns about the application's Israeli origin were raised by many bloggers in the Arab world, with belief that it may involve spying,[33] and believed that Viber collects users' critical information. These concerns were later featured by Al Arabiya News website,[34] referring to founder Talmon Marco serving with the Israeli army and having their development facilities in Israel. Later, in an interview with The Guardian, Marco stated that Viber was funded entirely by "friends and family" and that "We never took a single dollar from the state of Israel. We are not even incorporated in Israel. We maintain a research and development center in Israel and that's it (without a licence in Israel)."[29]


On July 24, 2013, Viber's support system was defaced by Syrian Electronic Army. According to Viber, no sensitive user information was accessed.[35]
