I grew up in a society where everything you did was eavesdropped on, recorded, snitched on. I had friends when we were kids getting into trouble for telling anecdotes about Communist leaders.

Everybody I meet who uses 'WhatsApp', I ask them a question: 'How did you hear about it?' And they say, 'My friends, my sister or my brother, somebody I know hounded me to install WhatsApp.' We think there is more power to the network when it grows organically.

I had so much fun in early days learning about networking, security, scalability and other geeky stuff.

When I was a kid trying to communicate with family in the Soviet Union, it was very difficult. You had to go through the long-distance phone companies like MCI, which were difficult to navigate and expensive to make calls through.

Communication is at the very core of our society. That's what makes us human.

I grew up in a home environment where I wasn't getting esteem for anything I did.
