About Me

David Sun cofounded and helps run Kingston Technology, which makes storage and memory products, as COO from a cubicle on the sales floor. With longtime partner John Tu, Sun launched a computer memory business out of a garage and sold it to now defunct PC maker AST a few years later. The pair started Kingston by making surface-mount memory chips after losing most of their first fortune in the stock market. Sun and his wife, Diana, have a foundation that provides grants to education programs for under-served youth in the U.S. and Taiwan. The company's name comes from one of John Tu's favorite bands, the Kingston Trio.
