Tackling the 'last mile' with Postmates CEO Bastian Lehmann

Sometimes Plan A doesn't work out. You've got to be ready to improvise.

That's one of the themes in Bastian Lehman's story. He had a different career path in mind, but ended up settling for entrepreneurship. So far it's going pretty well. He's the cofounder and CEO of Postmates, a delivery startup that's part of this race to remake the way we shop. He's raised about a quarter billion dollars.

Postmates was originally supposed to be doing furniture delivery. That didn't work out for some interesting reasons.

During the conversation, insights come in a live chat with Mike Isaac of the New York Times and Courtney Reagan of CNBC.
