Stars here (Silicon Valley) often get rich in their 20s, but the tech industry over all has been criticized as being stingy when it comes to public charity. Some executives, like Bill Gates, wait until they retire to become active philanthropists. Others, like Steve Jobs, may not give much publicly during their lives. And while there is evidence that the valley is more philanthropic than it seems, Ms. Arrillaga-Andreessen, 41, says more could be done.

“The word ‘philanthropy’ brings up an image of somebody who’s had an illustrious career, has retired and is giving to highly established institutions that may or may not have ivy growing up their walls,” she says. “I personally have felt the need to give philanthropy a reboot.”
