How Pavel Durov Built Telegram: A Security‑First Messaging Platform

Pavel Durov, often called the Russian Mark Zuckerberg, founded VK, Russia’s most popular social network with over 300 million users, and later created the privacy‑focused messaging app Telegram.

Born in Saint Petersburg, Durov spent much of his childhood in Turin, Italy, before returning to Russia for university. In 2006 he launched VK, borrowing many ideas from Facebook but adapting them for the Russian market.

His libertarian and anarchist views led to repeated conflicts with Russian authorities, including police raids in 2011 after he refused to shut down a VK opposition page, and a 2014 demand to censor his site, which he ignored by publishing the requested documents on his own page.

In 2013 Durov began developing Telegram as a side project. The app now boasts over 60 million monthly active users and processes more than 12 billion messages daily.

Telegram distinguishes itself in three key ways:

Security and privacy : Durov’s brother Nikolai, a multiple‑time International Olympiad in Mathematics and Informatics champion, designed the MTProto encryption protocol, which is fully open‑source and offers a $200 000 bounty for anyone who can break it.

No advertising or monetization : The company refuses ads, third‑party investment, or selling the service, prioritizing user privacy over profit.

Speed : Telegram’s code is highly optimized, with minimal dependencies, resulting in a lightweight Android client (13 MB) and iOS client (34.7 MB) that transmit data faster than many competitors.

The development team is distributed globally, often working remotely without a physical office. Telegram supports cross‑platform cloud sync and can transfer files up to 1.5 GB, though it currently lacks voice messaging.

Durov’s eccentric personality is evident in anecdotes such as folding 5 000‑ruble notes into paper airplanes and throwing them out a window, causing a street scramble.

In April of the previous year Durov stepped down as CEO and left Russia, taking his 12 % stake (worth roughly $400–$500 million) and moving to a European country with his team, which includes multiple ACM and programming competition champions.
