Larry Ellison cofounded software firm Oracle in 1977 to tap into the growing need for customer relationship management databases. He gave up the Oracle CEO role in 2014 but still serves as chairman of the board and chief technology officer. Oracle has grown in part through steady acquisitions of software companies, the biggest of which was $9.3 billion for Netsuite in 2016. In May 2016, Ellison pledged $200 million to the University of Southern California for a cancer treatment center. In 2012, Ellison spent $300 million to buy nearly all of Hawaiian island Lanai; so far, he has built a hydroponic farm and a luxury spa there. Ellison joined Tesla’s board in December 2018, after purchasing 3 million Tesla shares earlier that year.
