How Two “Crazy” Brothers Built Telegram
A story of privacy over dollars
What do some of the most iconic protests in Belarus, Hong-Kong, and Russia have in common?
One app: Telegram.
And governments around the world are trying to stop it.
In November of 2011, Pavel Durov looked out his window in Saint-Petersburg, Russia. He saw a team of armed, masked men approaching his building. They weren’t looking for drugs. They weren’t looking for money. They were looking for data.
Pavel was 26. He was the founder of VKontakte, the Facebook of Russia. And he had just refused a direct order from the Federal Security Service to hand over the personal data of Ukrainian protest organizers.
The message was clear: The state owns your data. The state owns you.
The police eventually left him unharmed that night, but Pavel had heard the message perfectly.
Every phone call could be listened to. Every message could be intercepted. Every platform he used was someone else’s property.
If he texted, the telecom provider would intercept it. If he emailed someone, the email provider could be required to turn them over. If he called, the line was tapped.
Pavel realized that even with millions of dollars and a massive tech company, he had zero digital freedom. He was naked.
We’re told the story of social media is a story of connection. Of sharing. Of a global village. But for Pavel Durov it was a story of surveillance. Of control. Of platforms that know you better than you know yourself, and governments that can knock on your door and ask for the keys.
Two years after that SWAT team visit, Pavel and his brother Nikolai, who co-founded VKontakte with him, became refugees. And with the money Pavel had left, they didn’t buy an island. They built a country. A digital country called Telegram.
Today, Telegram is a digital nation of over one billion active users. It has shaped elections, coordinated revolutions, facilitated economies, and terrified world governments from Moscow to Paris.
The insane part? They did all of this with zero advertising budget and a tiny team of just about 30 people. How did an app built by two Russian brothers reach 1 billion users without ads or selling user data? Why did WhatsApp and Facebook Messenger fail to stop it? And why did France arrest Pavel Durov?
This is a story of privacy over dollars.
The story of Telegram.
THE SEED
First, let’s meet the Durov brothers, the creators of Telegram. These Durov brothers are quite an odd pair.
Pavel, the younger one. The public face. Charismatic, ascetic, a libertarian who wears all black, trains in martial arts, posts shirtless photos on social media, and once threw paper airplanes made of 5,000-ruble notes, then worth about $155, out of his office’s window just because.
Pavel… is a meme.
And Nikolai… Older, reclusive, a mathematical genius who won gold at the International Math Olympiad three times in a row and built the technical backbone of everything they touched. He doesn’t do interviews. He doesn’t appear in photos. Nikolai is a ghost.
Together, they created VKontakte in 2006, Russia’s answer to Facebook, an app that became the country’s dominant social network.
By 2011, Pavel was worth hundreds of millions of dollars. He was untouchable.
Until he was not.
The government started demanding user data on opposition figures after disputed elections. Protesters’ names. IP addresses. Private messages.
Pavel refused.
When asked to ban opposition groups, he posted a picture of a dog sticking its tongue out as his “official answer to the security services.”
That’s when the knocks came at his door. By 2013, the pressure became unbearable.
Shareholders, some with ties to the Kremlin, forced him out of his own company.
He sold his shares for $300 million and in the aftermath of Crimea’s annexation in 2014, fled Russia with his brother Nikolai.
He told TechCrunch: “I’m out of Russia and have no plans to go back.”
They’d built something remarkable, only to lose it to powerful political interests.
But, now they had capital. They had skills. And they had a problem that wouldn’t leave them alone: How do you communicate when governments and tech giants want to read your messages?
This was the seed of Telegram. A messaging app that no government could tap, no corporation could harvest. Secure communication across borders, built for themselves at first, then offered to the world.
Pavel and Nikolai started building in 2013 while bouncing between places like Berlin, London, and Singapore. The team, composed of the two brothers and a core group of 15 computer programmers, was fully nomad by necessity.
They established Telegram in Berlin with a complex worldwide network of shell companies to avoid government interference.
Then Nikolai designed something called MTProto, an encryption protocol specifically engineered to be super fast, and resist state-level surveillance.
It was designed to challenge intelligence agencies that have billion-dollar budgets and legal authority to demand backdoors. The problem they saw wasn’t just “messaging.” It was the global hunger for private communication in an age where Silicon Valley giants were building walled gardens of data, and authoritarian regimes had developed an addiction to eavesdropping.
The early MVP was remarkably simple: encrypted “Secret Chats” that self-destruct. Fast messaging that works on spotty connections. Cloud sync that lets you access messages from any device. No phone number requirements for certain features.
But what made it really different was that Telegram didn’t ask you to choose between security and usability. WhatsApp was fast but owned by Facebook after a $19-billion acquisition in 2014. Signal was secure but kinda clunky. Telegram offered both, wrapped in a nice, clean interface.
Telegram’s positioning? A messaging app for people who need to stay alive.
Durov told Techcrunch: “The no. 1 reason for me to support and help launch Telegram was to build a means of communication that can’t be accessed by the Russian security agencies“
That clarity, that razor-sharp understanding of the problem, became Telegram’s moat.
While WhatsApp said “connect with friends“ and Signal said “privacy matters” Telegram was saying something more primal: “This cannot be taken from you.”
Digital sovereignty. That was the product.
That said, Telegram’s approach to privacy has always involved trade-offs.
Unlike Signal, which uses end-to-end encryption by default for everything, Telegram’s regular “Cloud Chats”, the ones most users rely on, are encrypted only between your device and Telegram’s servers.
This means the company technically could access message content if compelled or hacked, though Pavel insists they never have. True end-to-end encryption is optional, limited to one-on-one “Secret Chats” that don’t sync across devices.
Critics, including security experts, argue this prioritizes convenience, seamless multi-device access, unlimited storage, over maximum security, and that the custom MTProto protocol lacks the extensive peer review of industry standards.
THE SPARK
Telegram launched quietly on August 14th, 2013, on iOS first, then on Android on October 14th. But there was an issue: How do you get people to trust a proprietary encryption protocol built by two Russians?
So they find a clever solution. They launch with a stunt that most startups would never attempt:
A public cryptography contest with a $200,000 prize for anyone who could crack their encryption.
This is either brilliant or stupid.
If someone breaks it, Telegram is dead before it starts. If no one succeeds Telegram earns credibility that no amount of marketing could buy.
And no one breaks it.
The contest ran for years. Hackers tried. Security researchers tried. Intelligence agencies presumably tried in secret.
But MTProto held, even though the company gave $100,000 to one developer in Russia for finding a critical bug.
This victorious stunt created a huge amount of word of mouth in tech circles and among privacy-conscious users post-Snowden leaks.
By October 2013, Telegram already had 100,000 daily active users. By March 2014, it had reached 35 million monthly users and 15 million daily active users.
Telegram’s early word of mouth spread through a very specific network: activists, dissidents, journalists, and technologists, people who had something to lose if their messages were compromised.
People in places like Iran and Russia where surveillance was daily life. They spread it through niche networks because it worked when others failed, was fast even on slow connections, accessible from multiple devices without losing history.
Starting in September 2014, during the Hong Kong protests, activists switched to Telegram when they realized the government was monitoring other platforms.
Protesters needed coordination without leaders, real-time updates without censorship.
Telegram’s channels and supergroups, up to 200,000 members, became command centers. Downloads exploded. And Pavel Durov watched, fascinated.
In October 2014, South Korean government surveillance plans scared many citizens and made them switch to Telegram from the Korean app KakaoTalk.
Something remarkable was happening. Something I call “product-crisis fit.”
Whenever WhatsApp crashed, which it did periodically, Telegram downloads surged. Whenever Facebook faced a privacy scandal, which it did regularly and still does, Telegram downloads surged. Whenever a government cracked down on speech, which happens constantly somewhere in the world, Telegram downloads surged.
2020, Belarus, the opposition candidate uses a Telegram channel to organize the largest protests in the country’s history, coordinating hundreds of thousands of people through a single broadcast feed.
The government tries to block Telegram. It doesn’t work. Telegram’s architecture is designed to route around censorship, using a decentralized network of proxy servers that users can set up themselves.
In Iran, too, during repeated waves of unrest, Telegram became the uncensorable lifeline.
Telegram’s growth path was not paid acquisition. It was not gimmicky referral requests. It was crisis.
People switched to Telegram during moments of fear, anger, or betrayal. Then they stayed because the product was genuinely better in specific, measurable ways.
Speed for example. Telegram is fast. Messages are sent instantly even on weak connections. Files upload without compression. The interface is snappy and responsive in ways WhatsApp often isn’t.
And groups.
While WhatsApp limited groups to 256 people in the early days, Telegram allowed tens of thousands. This transformed Telegram from a chat app into a coordination tool.
And channels.
Telegram introduced “channels”, one-to-many broadcast tools where anyone can build an audience without going through an algorithm.
Part newsletter, part social network, part organizing platform. Before this, messaging apps were for talking with people, 1-to-1 or in small groups.
Telegram channels allowed you to broadcast messages, like Twitter.
And Bots.
Telegram opened up APIs that let developers build bots, automated tools that live inside chats.
Need a poll? There’s a bot. Need to translate? There’s a bot. Want to order food without leaving the app? There’s a bot for that too.
Telegram didn’t position against WhatsApp on some vague privacy claims. It positioned against all of social media on “control.” You control your data. You control your audience. You control your digital life.
GOING MAINSTREAM
By 2016, Telegram has 100 million users. By 2018, 200 million. Still tiny compared to WhatsApp’s billion-plus. But the users are engaged.
They’re spending hours per day in channels. They’re building communities. They’re creating sticker packs and bots and ecosystems.
The tiny team, never more than a few dozen engineers, nomadic, always relocating to evade political pressure, keeps shipping features that makes it stickier.
Then comes something enormous. A real black swan event.
January 6, 2021. WhatsApp announces a new privacy policy. Going forward, users must agree to share data with Facebook, including phone numbers, transaction data, and how they interact with businesses.
The backlash is instant. And user panic ensues.
Elon Musk tweets: “Use Signal.” Millions of people see that tweet. But something interesting happens.
Many download Signal. But even more download Telegram. Telegram become the most downloaded non-gaming app worldwide in January 2021.
Why?
Signal is secure but austere. It feels like a vegetable, good for you, but boring.
Telegram is fast, and it offers security plus stickers, video calls, channels, bots, massive groups, cloud storage, and a design language that’s modern rather than spartan.
Telegram feels like candy.
In three days, Telegram adds 25 million users. In January alone, more than 100 million people join. The servers strain but don’t break. Pavel tweets updates in real time, almost giddy in this chaos.
In October 2021, Telegram gains a record 70 million new users as Facebook experiences a nearly six-hour long outage across its services.
By 2022, Telegram passes 700 million users.
The growth isn’t linear. It’s exponential spikes triggered by external events, each crisis bringing a new wave that mostly stays.
And one thing makes Telegram’s growth unique: it manages to be both a tool for democracy activists and a platform for mainstream culture at the same time.
Channels become media empires. In Russia, some Telegram channels have millions of subscribers, more reach than TV networks. In India, regional language communities thrive. In Latin America, Telegram becomes the preferred platform for cryptocurrency discussion, finance tips, and neighborhood coordination.
Telegram isn’t hired for one job. It’s hired for dozens.
Protest coordination: “Help me organize without surveillance.” Community building: “Help me reach my audience without algorithms I do not control.” Private conversation: “Help me talk without being tracked. “Content discovery: “Help me find information my government is hiding.” Group coordination: “Help me manage a community of thousands.”
Every time you open Telegram, you don’t know what you’ll find. New channels. Fresh content. Breaking news your government doesn’t want you to see. It’s an information slot machine that makes the product super sticky.
And here’s a crucial detail: Telegram’s team is still under 50 people.
Pavel runs the company from Dubai, where he’s taken citizenship. The engineering team is distributed globally, bouncing between countries to avoid legal pressure. There’s no office. No extra bureaucracy. Every dollar not spent on bureaucracy is a dollar spent on servers, features, and survival.
By 2023, Telegram has 800 million users. In 2024, it crosses 900 million. And in March 2025, Telegram hits 1 billion users.
HEADWINDS
But success at this scale always comes with new problems. Problems Pavel never had to face when Telegram was just a tool for dissidents.
The same features that made Telegram powerful for activists also made it powerful for criminals.
Drug markets. Scam rings. Terrorist coordination. Child exploitation.
Pavel’s philosophy is absolutist: Telegram doesn’t read private messages. Ever. It moderates public channels based on local laws, but private chats are sacrosanct.
Critics call it negligence. Pavel calls it principles.
In 2018, Russia tries to block Telegram entirely after Pavel refuses to hand over encryption keys.
The ban fails spectacularly. Users simply route around it using VPNs and proxy servers. The government eventually gives up.
But the pressure doesn’t stop.
In 2024, Pavel Durov is arrested at Le Bourget airport in France. The charges: Telegram’s alleged failure to cooperate with law enforcement.
He’s released on €5 million bail after four days, initially barred from leaving France.
The arrest sends shockwaves through the tech world. Could a founder be held personally responsible for what users do on an encrypted platform?
Pavel doubled down. Quote
“If a tool can be used for good, it will also be used for bad. That’s not the tool’s fault.”
End quote.
But still, there was a small shift. In September 2024, Telegram conceded it would begin handing over IP addresses and phone numbers to authorities with valid warrants.
Beyond criminal misuse and regulatory pressure, Telegram faces ongoing criticism from privacy experts.
Default chats aren’t end-to-end encrypted, requiring users to manually enable “Secret Chats” for true protection, a step most don’t take.
The proprietary MTProto protocol, while refined over years, is seen by some as less battle-tested than open standards like Signal’s. And requiring a phone number for signup reduces anonymity.
Pavel defends these as necessary for speed, features, and mass adoption, arguing perfect privacy would sacrifice the usability that made Telegram a billion-user platform.
Meanwhile, competitors are circling. WhatsApp, Signal, iMessage: all adding features Telegram pioneered.
So far, none have cracked Telegram’s core positioning: privacy and usability.
But there’s another challenge: money.
Telegram has never charged users. Never ran ads. Pavel personally funded it for a decade, burning through hundreds of millions.
By 2021, hosting a billion users with unlimited cloud storage becomes unsustainable.
Pavel’s solution? Totally unconventional.
He doesn’t raise venture capital, he uses debt financing by issuing bonds. Over $1 billion raised while maintaining complete independence.
Then he introduces ads, but only in large public channels, only text-based, no personal data harvesting.
He launches Telegram Premium for power users, while the free version stays fully functional.
With this contrarian strategy, Telegram survives without becoming a surveillance platform. Without selling user data. Without compromise.
This is the luxury afforded by being mission-driven rather than investor-driven. Pavel never went public. Never gave up control.
While WhatsApp sold to Facebook for $19 billion, Telegram issued bonds. While Snapchat IPO’d under shareholder pressure, Telegram stayed private. This was the opposite of every tech playbook. And that’s why Telegram could stay Telegram.
CONCLUSION
If there’s one thing we can take away from Telegram’s story, it’s this: Telegram achieved product-market fit by selling something rarer than features.
Digital freedom.
In a world where free apps harvest your life, Telegram offers a powerful blend of privacy and usability. Though that privacy is not perfect for everyone: for maximum security, users must opt into Secret Chats and trust Telegram’s servers for everything else.
But every feature like encryption, channels, bots, groups, reinforces the same insight: you don’t have to choose between privacy and usability.
Users needed that. For secrets. For coordination. For saving lives. And also, for fun.
Telegram’s success endures because it chose a small, viable market first: people who couldn’t afford to be watched.
Then stayed true to that vision as the world caught up.
Today, Telegram is profitable. It’s uncensored. It’s a digital nation of more than a billion citizens…
With a two-person government.
