NET WORTH: $8.5 billion
SOURCE OF WEALTH: Cofounder of WhatsApp
FUNDING AREAS: TBD
OVERVIEW: Koum is still relatively new to philanthropy, so it's difficult to say what causes he'll support. However, he recently put close to $556 million into a donor-advised fund at the Silicon Valley Community Foundation. The full scope of his giving through that fund remains unclear, but we do know that he gave $1 million to support a free open source operating system that is used by start ups.
BACKGROUND: Jan Koum was born in Kiev, Ukraine to a Jewish family. He moved with his mother and grandmother to the bay area in the early 1990s, where a social support program helped the family to get a small two-bedroom apartment. Koum enrolled at San Jose State University while simultaneously taking a job as a security tester at Ernst & Young. That led to a job as an infrastructure engineer at Yahoo. His work at Yahoo became all-consuming, and he dropped out of college to work at Yahoo full-time.
He soon met Brian Acton, another early Yahoo employee, and in 2009, the pair started WhatsApp, a cross-platform mobile messaging app that allows users to send text messages for free. Facebook bought the startup for $19 billion in cash and stock in 2014.
TECHNOLOGY: Koum's one public gift so far has been $1 million to the FreeBSD Foundation through SVCF. FreeBSD describes itself as an "an advanced computer operating system used to power modern servers, desktops and embedded platforms." Koum made a post about the gift on Facebook and talked about how the FreeBSD Foundation has helped support the operating system that allows "millions of programmers to pursue their passions and bring their ideas to life."
Koum then lists himself as one of the many programmers who have used FreeBSD. In fact, Koum credits FreeBSD for helping him get out of poverty and hopes that it will help other people in similar situations to do the same: "We’ll all benefit if FreeBSD can continue to give people the same opportunity it gave me—if it can lift more immigrant kids out of poverty, and help more startups build something successful."
LOOKING FORWARD: Koum is still young and still engaged in business, so he's got plenty of time to focus on philanthropy down the line. Koum's background might come into play, perhaps helping immigrants or the poor. It's worth noting that Koum's mother passed away from cancer, so health might become a philanthropic interest too. Now that Koum is linked to the SVCF, one might also consider the kinds of investments SVCF makes, such as education.
