Super Pumped: The Battle for Uber by Mike Isaac:
Once Google had bought Levandowski’s startup, he dove headlong into mapping and self-driving tech for his superiors, joining the secretive Google X division. Colleagues said Levandowski deserved much of the credit for convincing Google’s top brass, especially Larry Page, to pour millions into self-driving research. And by virtue of working on a project dear to the CEO’s heart, Levandowski began to develop a special relationship with Page.
But he was also shrewd. When Google ought 510 Systems, Levandowski sold it for just under the amount that would have required him to share the profits with the fifty or so employees under him, depriving dozens of his colleague of a rich payday. Even worse, Google hired less than half of 510 Systems’ staff. The rest had little to show for their time spent working on Levandowski’s robots.
