Back in the summer of 2013, just as Silicon Valley investors were moving from optimism to outright exuberance, Travis Kalanick set out to raise Uber’s fourth round of financing. Colleagues say Kalanick set the terms of the financing round himself. He initiated discussions with half a dozen large investors and ran the process as an auction, searching not just for the most capital at the highest valuation, but for a powerful partner who could facilitate Uber’s coming global expansion. Yuri Milner’s fund, Digital Sky Technologies, was involved in the bidding, as was the venture capital firm General Catalyst Partners. But ultimately Kalanick’s attention settled on the dominant technology company in the land—Google.
