The Voice Over Internet Protocol cellular-telephone application Viber, launched by Israel's iMesh company in 2011, has been sold to Japanese trading giant Rakuten for $900 million. Viber started as a way to call for free on cell phones and a feature was added for sending messages similar to the What's Up app. Last May, the company released an application for the home computer to compete with Skype.
Viber is in the top 100 apps for Androids and other cell phones in the United States and the top thousand in China. With about 130 people on the staff, iMesh is headquartered in Cyprus, with development carried out in Israel and Belarus.
