I don't think you should ever start a business and move in a direction where you can't see it becoming a business.

Instagram is a media company. I think we're about visual media. I explain ourselves as a disruptive entertainment platform that enables communication through visual media. I don't think it's just photos. There's a reason we don't allow you to upload photos on the Web as albums. It's not about taking all these photos off your DSLR putting them into an album and sharing them with your family. It's not about that. It's about what are you up to right now out in the real world, how can you share that with everyone.

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.

The number of people who have either gotten married or had kids or started dating or just made great friends over Instagram is countless. I think we're the only platform that continues to be successful in bringing people together in real life for these real relationships.

I believe photos is one of the underlying things in every social network that becomes successful.

Great products sell themselves.

People have presences, both online and in real life. You can choose to show everything, meaning all sides of you, or you can choose to be selective.
