Viber

Did you know that one of the most globally used messaging apps, Viber, was actually created by a native of Nizhny Novgorod, Russia? The mastermind behind it is Igor Magazinnik, currently residing in Israel. He sold his brainchild back in 2014 for almost a billion dollars and now he's onto a new venture - a taxi service called Juno that aims to rival Uber in New York City.
