This week on the podcast? DoorDash cofounder and CEO Tony Xu. He just raised more than half a billion dollars to build out his business. 

There’s this idea out there that today’s consumers are lazy, and that’s why we're getting stuff delivered all the time. The thing is, I don’t know about you – but the reason why I’m ordering so much delivery is because I’m so busy.  

That’s where DoorDash comes in. The company was cooked up by four students at Stanford four and a half years ago. One of the four, Tony Xu, is the company's 33-year-old CEO. 

Xu was in New York recently after raising a monster round of funding – $535 million. I sat down with him at the Nasdaq MarketSite in Times Square to find out what he's really building, and why he thinks he can beat Grubhub, Amazon, Google, and a lot more rivals lining up to take him on.
