There's a massive opportunity as more and more millennials and others in cities switch over from car ownership to transportation as a service. They are picking Lyft, and we want to stay focused on that big opportunity.

When I left my job at Lehman Brothers to start a company, my best friend's mother said, 'How could you leave a sure thing like Lehman to do a silly carpool startup?' That was three months before Lehman went bankrupt.

We see Lyft as not just an app, but a movement of people coming together in cities and having conversations about things that matter. You're around some of the most interesting people in the world, and you don't talk to them. More and more people are craving in-person interactions.

The Gmail app is definitely the app I use the most. I am always running from meeting to meeting, so it keeps me up-to-date with everything going on. I actually e-mail more often from my iPhone than my laptop, so having a nicely designed e-mail app is really important.
