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

I always look toward teens on Instagram to really understand what's going on. For some reason, when you're a teen, you just understand the world better than anyone else.

If you've got an idea, start today. There's no better time than now to get going. That doesn't mean quit your job and jump into your idea 100 percent from day one, but there's always small progress that can be made to start the movement.

I really appreciate crafts. I like cooking. I love food and drink. I love owning that through Instagram. Although that can be challenging at times because it doesn't fit people's stereotypes of a technical founder.

Instagram is a media company. I think we're about visual media.

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.

The major reason why Instagram works is that you can follow anyone out there and start following their photos immediately.
