Digital Fortress LLC was a company created by Neff in his home city of Buffalo, New York in 2012,[17] and co-founded by Pavel Durov. It is engaged in the management and financing of mobile applications. Neff served as the director of this company. Digital Fortress LLC maintained its headquarters in Buffalo, New York.[18] In early 2013 the company bought 96 terabytesofinfrastructure from QBC Systems.[19] In April of that same year, Pavel Durov said that Digital Fortress was a cloud cluster, that was created for the benefit of startups from the Start Fellows.[20]
On August 14, 2013,[21] the company released its first experimental application, called Telegram. Telegram is a freemium instant messaging application for smartphones that was built using a new encryption algorithm called MTProto,[22] which was created by Pavel Durov's Brother, Nikolai Durov.[23][24]
In January 2013, the news channel TV Rain reported that Neff's Digital Fortress company was working on a new project.[25] At that time, it was reported the first application to be supported by Digital Fortress would be called telegra.ph, for which a domain had already been registered.[19] Later this name was dropped in favor of Telegram.[26]
On August 14, 2013 the application was released on the Apple iOS platform. At the same time, a contest was announced to solicit developers to assist in developing the application on Android, referred to as "Durov's Android Challenge".[27]
Shortly following the release of Telegram, Durov publicly spoke with Izvestia stating that "Telegram, strictly speaking is not my project". In this interview he explained that the project he partially supported by investments was Digital Fortress, a cloud hosting platform for projects like Telegram among others.[28]
Three weeks after the launch of Telegram, it began to see nearly immediate success. Every day more than 100 000 new registered users began to appear on the network. Most of whom were from Arab countries.[29]
A few months later in 2014, following the sale of WhatsApptoFacebook,[30] Telegram saw a major growth spike when nearly 5 million new users registered in a single day.[31]
