Billionaire tech investor Marc Andreessen lists his stunning Silicon Valley compound for $33M after splurging a quarter of a BILLION dollars on Malibu mansions

Tech titan Marc Andreessen is deserting Silicon Valley for the beach at Malibu after listing his mansion in Atherton for $33 million.

The Netscape co-founder and Mosaic inventor already has a string of homes in the seaside town including a seven-acre property in Paradise Cove which he bought for $177 million in 2021.

That made it the most expensive home ever bought in California, a record that stood until 2023 when Jay Z and Beyonce paid $200 million for the house next door.

But his home in the San Francisco suburbs is nothing to sniff at either, boasting 12,200 square feet, five luxurious bedrooms and a pristine interior after a four-year renovation.

'This hidden jewel situated on 1.55 acres barely discernible from the street and positioned across from the esteemed Menlo Circus Club, is one of Atherton's most exceptional estates,' the blurb from realtor Compass claims.

The 1.5 acre property boasts manicured lawns, a covered terrace, pergola, fountains, seven fireplaces and a reflecting pool 

'While the outside symmetry and classic allure endure, it has evolved into a place of chic sophistication,' the realtors claim 

Four years of renovation has just concluded on the home's pristine interior 

Marc Andreessen has put his mansion in Atherton on the market for $33 million, where neighbors include ex-Google CEO Eric Schmidt and NBA star Steph Curry 

'While the outside symmetry and classic allure endure, it has evolved into a place of chic sophistication.'

Andreessen bought the three-story home with 1.5 acres manicured lawns, a covered terrace, pergola, fountains and a reflecting pool for $16.6 million in 2007.

The tech investor has a $1.7 billion fortune boosted by the investment vehicle Andreessen Horowitz which he founded in 2009 and has backed rising stars including Facebook, Coinbase, and Slack.

And he has spent more than $255 million on three homes in Malibu alone since 2021.

Married to real estate heir Laura Arrillaga since 2006 he bought a home on Escondido Beach for $44.5 million in 2022 and then a beach house near the Paradise Cove compound for $34 million.

And he may have grown tired of his neighbors in Atherton after losing a battle to prevent an affordable housing development in the neighborhood last year.

Andreessen, 52, who sold Netscape to AOL for $4.2 billion in 1998 wrote of his frustration at America's housing problem in a 2020 article entitled 'It's Time To Build'.

He slammed 'crazily skyrocketing housing prices', calling for more housing projects 'in all our best cities at levels way beyond what we have now'.

'We need to want these things more than we want to prevent these things,' he thundered.

But he reacted with horror last year when Atherton came forward with plans to introduce affordable housing with 16 three-story townhouses in his neighborhood.

He joined wealthy neighbors including NBA star Steph Curry, himself the owner of a $31 million home, in demanding an end to the project.

The Netscape founder, who married real estate heir Laura Arrillaga in 2006, runs investment vehicle Andreessen Horowitz and has a fortune of $1.7 billion   

In an email to the town council he hit the caps lock button to declare he was 'IMMENSELY AGAINST multifamily development', and demand they 'please IMMEDIATELY REMOVE' the project's plans from the area.

The project went back in a scaled back form and may have contributed to a fall in Atherton's median home sale price from $8.3 million to $5.7 million in the two years to February.

But Andreesson's home is not even the most expensive listed on his Compass's website where $42 million is being asked for a house up the road.

'Recently we have seen multiple offers on homes listed for over $20 million, which shows the competitive nature of the luxury market,' said Compass founder Mary Gullixson.
