Andreessen is married to Laura Arrillaga-Andreessen, whose Silicon Valley real estate mogul father bought land in Solano County decades before his death in 2022, according to county records obtained by TechCrunch. An LLC operated by Arrillaga-Andreessen’s brother that’s known as A&P Children Investments, has begun the planning process for a mixed-use development with more than 1,000 homes.

This area is on the edge of the city of Vacaville, 10 miles away from the proposed California Forever development, according to property records, planning documents, and business registry information viewed by TechCrunch. A representative for A&P said at a community meeting in March that A&P plans to ultimately sell the property for the benefit of Arrillaga-Andreessen and her brother, John Arrillaga Jr.
