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 store'.

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, unlike Skype which is modeled after a 'buddy list' requiring registration and a password. Sani Maroli and Ofer Smocha soon joined the company as well. The company was run from Israel, with much of its development outsourced to Belarus in order to lower labor costs. 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.
