82. Larry Ellison, Mark Hurd, Safra Catz

CEO (Hurd and Catz), CTO and founder (Ellison), Oracle

In the first year since Ellison, the Oracle founder and chairman, stepped down as CEO — he moved to the role of chief technology officer and was succeeded by co-CEOs Hurd and Catz — the company has set off on a startup-buying spree. In its fifth and most recent acquisition of 2016, Oracle purchased Opower, a cloud-based energy-management company used by more than half of the world's largest utility companies, for $532 million. Before that it bought another cloud-services company, Textura, for $663 million, expanding its offerings in the construction industry.

Though Oracle's cloud business is still just a fraction of the company's overall revenue, Ellison thinks it could lead Oracle to become the first cloud-computing business to reach $10 billion in revenue. Catz was the top-paid female executive in 2015, earning nearly $57 million.
