Marc Andreessen is giving house hunters another chance of buying his longtime home.

The billionaire tech investor, along with his wife, the philanthropist Laura Arrillaga-Andreessen, has decided to relist their 12,000-square-foot Atherton, California estate for $29.5 million, a slight decrease from its previous price as reported by Bloomberg.

The 1.55-acre property was quietly relisted on May 23 after sitting unsold for most of last year before being withdrawn in November.

Andreessen, who is one of the co-founders of the venture capital firm Andreessen Horowitz (a16z) and an early supporter of companies such as Meta, Airbnb, and Lyft, purchased the estate back in 2007 for $16.6 million.

The couple’s decision to revisit the listing comes amid a broader lifestyle shift.

Recently, Andreessen has been dividing his time between Florida and Washington, showing support for President Donald Trump, who has close ties to several former employees of a16z and its associated companies.

The Atherton residence is shielded from view by dense hedges — a common feature in a town that consistently ranks as one of America’s richest ZIP codes. 

Behind the privacy barrier, the home includes five bedrooms, seven bathrooms, two kitchens, seven fireplaces, a one-bedroom guesthouse and a three-car garage. 

It is being marketed by Brent and Mary Gullixson of Compass Real Estate. Brent Gullixson declined to comment on the listing.

While Andreessen hails from Wisconsin, Arrillaga-Andreessen is closely tied to the Bay Area. Her late father, John Arrillaga, played a central role in shaping modern Silicon Valley by developing tens of millions of square feet of office space for tech giants including Apple, Cisco and Google alongside his longtime partner Richard Peery.

In recent years, the couple has expanded their footprint in Southern California, acquiring three Malibu estates — most notably a $177 million blufftop compound in 2021 that broke price records statewide.

Subsequent purchases included a $44.5 million home and a $34 million spread nearby, according to previous reports in the Wall Street Journal.

The Andreessens made headlines in 2022 for their fierce opposition to a proposed multifamily housing development in Atherton, writing in a letter that the plan would “MASSIVELY decrease our home values,” raise traffic and lower residents’ quality of life. 

Despite pushback from affluent locals, the town ultimately adopted a rezoning plan to allow more housing in October 2024.

The couple did not respond to a request for comment.
