Boasting 5 qualifications from Stanford University (including 1 from nursery school), to which her late father donated US$300 million, Laura Arrillaga-Andreessen is a professor and philanthropist

Venture capitalist Marc Andreessen and his wife, Laura Arrillaga-Andreessen, are making headlines again – but this time, it’s not just about tech investments. Laura, along with brother John Arrillaga Jr, is behind an enormous development project in Solano County, California, per TechCrunch. The pair, through a company run by John, are plotting a mixed-use community close to the proposed California Forever utopian city – the brainchild of Andreessen and his Silicon Valley friends.

But here’s the kicker: the land with which they’re working. It’s been in the family for decades, scooped up by Laura’s father, real-estate legend John Arrillaga Sr, back in 1985. And while California Forever has been grabbing headlines, it turns out the Arrillaga clan’s additional plans have been quietly in the works for years; and they might just cash in big time, thanks to all the attention on their famous tech neighbours.

But Laura is more than John Arrillaga’s daughter and Marc Andreessen’s wife. She is a founder, educator and best-selling author working to empower women to pursue leadership roles.

With an MBA, an MA in education, not one, but two degrees in art history and a certificate from Stanford’s Bing Nursery School, she’s racked up five diplomas from the Californian institution, per her foundation’s website.

John Arrillaga Sr donated more than US$300 million to Stanford during his lifetime, according to the private university.
