Marc Andreessen is giving house hunters another chance of buying his longtime home.
The billionaire tech investor and his wife, the philanthropist Laura Arrillaga-Andreessen, have put their 12,000-square-foot Atherton, California estate back on the market for $29.5 million, roughly $4 million below its previous listing price, according to 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The 1.55-acre property was quietly relisted on May 23 after sitting unsold for most of last year before being withdrawn in November.

The five-bedroom estate, purchased in 2007 for $16.6 million, sat on the market for eight months before being pulled last November. Bernard AndreAndreessen, a co-founder of venture capital firm Andreessen Horowitz (a16z) — and an early backer of companies like Meta, Airbnb and Lyft — bought the property in 2007 for $16.6 million.
The couple’s decision to revisit the listing comes amid a broader lifestyle shift.
Andreessen has been spending increasing time in Florida and Washington, aligning himself with President Donald Trump, whose inner circle includes several alumni of a16z and its portfolio 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.

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.

The couple, who have shifted their focus to Malibu and other states like Florida and Washington, have made headlines for their high-profile real estate purchases — including a $177 million Malibu compound — and their opposition to local housing developments in Atherton, which they argued would diminish property values and quality of life. FilmMagicSubsequent 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.
