¨Pavel Valerievich Durov ( Russisch : а́вел Вале́рьевич ов ; born October 10, 1984) is a Russian-born entrepreneur who is best known as the founder of the social networking site VK and later the Telegram Messenger .  He is the younger brother of Nikolai Durov . Since their resignation as CEO of VK in 2014  have the Durov brothers traveled the world in self-imposed exile  as citizens of Saint Kitts and Nevis .
