• WhatsApp co-founder Brian Acton is currently the 76 th richest person in America, with a net worth of nearly $7 billion.

  • Rather than spending lavishly, the tech billionaire seems to focus on investing and philanthropy.

Brian Acton, co-founder of WhatsApp, has always known how to make strides in Silicon Valley.

Most recently, he injected $50 million of his own money into encrypted chat app Signal, helping launch the Signal Foundation.

But to the 76th richest person in America, that amount barely makes a dent in the bank account. Acton has a net worth of $6.9 billion, according to Forbes.

That’s a long ways away from his Yahoo days.

Acton and his WhatsApp co-founder, Jan Koum, started the company after leaving Yahoo, and it has since become one of the most popular mobile messaging apps in the world. In 2014, WhatsApp was acquired by Facebook for $22 billion - and Acton received about $3 billion from the sale.

Acton keeps a low profile in Silicon Valley. While not much is known about how he spends his money in his personal life, it is clear that the Stanford alum has a penchant for investments and philanthropy.

Acton's foray into philanthropy began with Sunlight Giving, which he launched in 2014 with his wife, Tegan Acton. It supports the basic needs of low-income families with children age five and below in the Bay Area, including support for safe spaces and organizations that provide food security, family support resources, housing stability, and health care access. With $470 million in assets, it grants more and more money each year — $6.4 million in 2015, $19.2 million in 2016, and $23.6 million in 2017.

Around the same time, Acton also launched Family Giving, a donor-advised fund at Fidelity Charitable, which supports initiatives with a close connection to Acton and his family such as building empathy in society. Current initiatives include supporting first-person storytelling and promoting compassion for vulnerable animals throughout the world.
