Biography Timeline

1992

Koum was born in Kyiv, Ukraine, then in the Soviet Union. He is of Jewish origin. He grew up in Fastiv, outside Kyiv, and moved with his mother and grandmother to Mountain View, California in 1992, where a social support program helped the family to get a small two-bedroom apartment, at the age of 16. His father had intended to join the family later, but he never left Ukraine, and died in 1997. Koum and his mother remained in touch with his father until his death. At first Koum's mother worked as a babysitter, while he himself worked as a cleaner at a grocery store. His mother died in 2000 after a long battle with cancer.

1996

By the age of 18 Koum became interested in programming. He enrolled at San Jose State University and simultaneously worked at Ernst & Young as a security tester. He also joined a group of hackers that began in 1996 called w00w00, where he met the future founders of Napster, Shawn Fanning and Jordan Ritter.

In February 1996, a restraining order was granted against Koum in state court in San Jose, California. An ex-girlfriend detailed incidents in which she said Koum verbally and physically threatened her. In October 2014, Koum said about the restraining order, "I am ashamed of the way I acted and ashamed that my behavior forced her to take legal action".

1997

In 1997, Koum met Brian Acton while working at Ernst & Young as a security tester.

Later in 1997, Koum was hired by Yahoo! as an infrastructure engineer. He quit school shortly thereafter. Over the next nine years, Koum and Acton worked there together. In September 2007, they both left Yahoo! and took a year off, traveling around South America and playing ultimate frisbee. Both applied to work at Facebook, and both were rejected.

2009

In January 2009, Koum bought an iPhone and realized that the then seven-month-old App Store was about to spawn a whole new industry of apps. He visited his friend Alex Fishman and they talked for hours about Koum's idea for an app. Koum almost immediately chose the name WhatsApp because it sounded like "what's up", and a week later on his birthday, February 24, 2009, he incorporated WhatsApp Inc. in California.

WhatsApp was initially unpopular, but its fortunes began to turn after Apple added push notification ability to apps in June 2009. Koum changed WhatsApp to "ping" users when they received a message, and soon afterwards he and Fishman's Russian friends in the area began to use WhatsApp as a messaging tool, in place of SMS. The app gained a large user base, and Koum convinced Acton, then unemployed, to join the company. Koum granted Acton co-founder status after Acton managed to bring in $250,000 in seed funding.

2012

Koum dislikes being called an entrepreneur, going so far as to post on Twitter in 2012, "Next person to call me an entrepreneur is getting punched in the face by my bodyguard." He feels that he is not an entrepreneur because entrepreneurs are motivated by the desire to make money, whereas he only wants to build useful products.

2014

On February 9, 2014 Zuckerberg asked Koum to have dinner at his home, and formally proposed Koum a deal to join the Facebook board. Ten days later Facebook announced that it was acquiring WhatsApp for US$19 billion.

In November 2014, Koum donated $1 million to The FreeBSD Foundation, and close to $556 million to the Silicon Valley Community Foundation (SVCF) the same year. In December 2016, Koum donated another $500,000 to The FreeBSD Foundation, followed by $250,000 donations in 2018 and 2019

2017

In 2017, Koum began posting messages on Facebook in support of U.S. President Donald Trump. In September 2017, he wrote on Facebook, "as somebody who grew up in Soviet Union, Donald Trump couldn't be more right about failures of socialism...".

2018

In April 2018, Koum announced that he was leaving WhatsApp and stepping down from Facebook's board of directors due to disputes with Facebook. It was originally thought that by leaving he was forfeiting his unvested stock, worth almost $1 billion. However, several months later it was discovered that he was still formally employed by Facebook, earning a reported $450 million in stock from the company through a method called "rest and vest."

Family Life

Jan Koum moved to America in 1992 with his mother and grandmother. Jan Koum's father planned to join them, but passed away in the Ukraine in 1997.
