It was New Year's Eve, 2003, and Oracle Corp. (ORCL ) CEO Lawrence J. Ellison was on his honeymoon. He and his bride, romance novelist Melanie Craft, were relaxing on his 243-foot Katana yacht off St. Barts, the Caribbean island known as a haven for movie moguls and rock stars. But Ellison, for the umpteenth time, couldn't help himself. He climbed to his office on the upper deck of the Katana, fired up his computer, and logged on to the Web site of a small company called NetSuite Inc. It was the last day of the fiscal year, and Ellison, the co-founder of NetSuite and its largest investor, needed to know if the startup was going to meet its numbers.
