Our goal is to not just be a photo-sharing app, but to be the way you share your life when you're on the go.

Every startup should address a real and demonstrated need in the world. If you build a solution to a problem lots of people have, it's so easy to sell your product to the world.

I love challenging the notion that, in order to be a tech founder, you have to be holed up in a dark room wearing a T-shirt and baggy jeans.

With Instagram, the focus is on the present tense.

Everyone gets lucky for some amount in their life. And the question is, are you alert enough to know you're being lucky or you're becoming lucky?

I actually think some of my best moments in life have been while I was with people from Instagram - whether it's super late nights getting a release out or being able to travel to places I'd never visited and meeting some of the most interesting people I've ever met.

We're just taking people and shifting them from taking photos anyway to taking them on Instagram.
