16. Larry Ellison
Larry Ellison proves once again that nobody makes databases faster and more powerful. His latest creation from Redwood Shores, Calif.-based Oracle: a 12c in-memory database that powers 100 to 1,000 times faster queries. The database is so fast that some beta customers thought the database was somehow "broken," boasts Ellison. Broken? No. Breaking the mold for databases and software entrepreneurs? Yes.
