On 13 February 2014, Rakuten announced they had acquired Viber Media for $900 million. According to Viber, no sensitive user information was accessed.

On 24 July 2013, Viber's support system was defaced by the Syrian Electronic Army. They invested $20 million in the company, which had 120 employees as of May 2013. The company was originally funded by individual investors, described by Marco as 'friends and family'. It began doing so in 2013, via user payments for Viber Out voice calling and the Viber graphical messaging 'sticker market'. In its first two years of availability, Viber did not generate revenues.

Marco commented that Viber allows instant calling and synchronization with contacts because the ID is the user's cell number. Sani Maroli and Ofer Smocha soon joined the company as well. The company was run from Israel, and was registered in Cyprus. Marco and Magazinnik are also co-founders of the P2P media and file-sharing client iMesh. Viber Media was founded in Tel Aviv, Israel, in 2010 by Talmon Marco and Igor Magazinnik, who are friends from the Israel Defense Forces where they were chief information officers. It is based in Cyprus with offices in London, Manila, Moscow, Paris, San Francisco, Singapore, and Tokyo. Since 2017, its corporate name has been Rakuten Viber. The software was developed in 2010 by Cyprus-based Viber Media, which was bought by Rakuten in 2014. As of 2018, there are over a billion registered users on the network. In addition to instant messaging it allows users to exchange media such as images and video records, and also provides a paid international landline and mobile calling service called Viber Out. Users are registered and identified through a cellular telephone number, although the service is accessible on desktop platforms without needing mobile connectivity. Viber, or Rakuten Viber, is a cross-platform voice over IP (VoIP) and instant messaging (IM) software application owned by Japanese multinational company Rakuten, provided as freeware for the Google Android, iOS, Microsoft Windows, Apple macOS and Linux platforms.
