In America’s richest town, it’s go big or go home.
According to a Variety report published this week, Jan Koum, the billionaire cofounder of WhatsApp, has spent almost $80 million buying and constructing what may just be the most expensive property in America’s richest town, Atherton, California, where the average household income was $450,696 in 2017, according to Bloomberg.
Koum reportedly configured the compound by dropping $57 million over four years to acquire and renovate five houses in Atherton, then spent over $20 million adding at least two mansions and a two-level detached garage that’s likely over 10,000 square feet.

Koum sold WhatsApp to Facebook for $19 billion in 2014 and joined the company’s board of directors. After the deal, he sold over $7.1 billion worth of Facebook shares and was living the good life in Silicon Valley “resting and vesting,” a term used to describe engineers who have small workloads and high-priced stocks.
