Though it's not mentioned in the article, Uber recently partnered with Concur for business travel. Uber now sends all my ride receipts directly Concur, and my expense reports are populated automatically -- it's first-class integration right in the app.

And now Uber is opening their API? IMO, this is a huge deal. Perhaps working with Concur really drove home the sheer size of the corporate travel machine, and the massive opportunities they were missing out on by not participating in its web of partners and exclusive contracts. I know Uber already has VIP (in NYC at least) and is coming out with corporate discounts, but I'm betting we see Uber move a lot more in that direction.
