The world is now awash in data and we can see consumers in a lot clearer ways.

If I see what you're up to on Facebook but I don't see your updates on Flickr, I'll still care about Facebook.

Being an entrepreneur is not about being in love with an idea, it's about being in love with running a company.

I think the hallmark of a really good entrepreneur is that you're not really going to build one specific company. The goal - at least the way I think about entrepreneurship - is you realize one day that you can't really work for anyone else. You have to start your own thing. It almost doesn't matter what that thing is.

Having a highly homogeneous background, education, values, preferences, etc, in the very early team is better than not - cuts down on time-wasting arguments.

You can have successful teams where people hate but deeply respect each other; the opposite (love but not respect among team members) is a recipe for disaster.

I've been developing mobile for years before anybody else really thought it was that important.
