David Sun

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.
