He is a billionaire today but his early life is full of difficulties.

Born into a humble family in Ukraine, he migrated to the United States as a teenager with his mother and grandmother. His initial years in the new country were very difficult; the family struggled to make ends meet. Their situation worsened when his mother became ill with cancer and eventually passed away. A resilient soul, Jan Koum worked his way through high school, and found a job at Yahoo as an infrastructure engineer, while still attending college.

And he got friend Brian Acton in Yahoo, Brian is also working at Yahoo.

Their love for social media ultimately led the two men to form WhatsApp as a mobile messaging application which went on to become the most popular messaging platform in the world.

Childhood & Early Life

Jan Koum was born on February 24, 1976, in Kyiv, Ukrainian SSR, Soviet Union, to Jewish parents as their only child. He lived a simple life in a small town that was disrupted by the chaotic political environment and anti-Semitism in the country.

To escape the unfavorable conditions in their native land, the family decided to migrate to the United States. Jan, along with his mother and grandmother moved to the US in 1992, and his father planned to join the family later. However, his father fell ill in Ukraine and could not make it to the US. He died in 1997.
Aged 16 at the time of the immigration, Jan faced considerable challenges in adjusting to the new country. His mother took up babysitting to earn money and Jan himself began working as a cleaner at a grocery store.
He became interested in programming while at high school and discovered that he possessed an inherent knack for it. By the time he completed his schooling at 18, he was a skilled self-taught computer network engineer.
He enrolled at the San Jose State University. While still a student he took up a job with global accountants Ernst & Young as a security tester to help pay for his studies.

On his job, Jan Kuom was assigned to the new search engine Yahoo to inspect security levels at the company’s advertising system. While working on this, he became acquainted with Brian Acton, one of Yahoo’s earliest employees. The two men shared many similarities and struck up an immediate rapport as both of them had a similar no-nonsense approach to working.


After a few months Koum joined Yahoo as an infrastructure engineer, while still attending San Jose State University. A few days after his joining Yahoo suffered a systems breakdown, and Koum—who was attending a class at that time—was immediately called to help with the problem.

At this juncture Koum realized that he would have to choose either the university or Yahoo, and he chose the latter.
Koum and Acton worked together at Yahoo for nine years. During this time they not only became good friends, but also realized their mutual interest in the fast growing social media world. However, Yahoo did not offer them the opportunity to explore social media, so they quit their jobs in 2007 to explore newer avenues.


Both Koum and Acton took a year off and travelled around South America. On their return to the US, both of them individually applied for jobs at Facebook and Twitter, and both were rejected by both companies.


In 2009, Koum bought a new iPhone. On visiting one of the first App Stores to open, he realized the potential offered by the market for iPhone compatible applications. This gave him the idea for an application for low-cost convenient communication.

Excited with the idea, he roped in Acton and the two men incorporated their new company—called WhatsApp Inc.—on Koum’s birthday, February 24, 2009. One of their fundamental principles was that their company would never accept any form of advertising revenue.


The duo launched the WhatsApp Messenger in early 2010. The early messenger kept crashing and the men faced many challenges in promoting the application. Frustrated after a few months of trying, Koum was on the verge of giving up when Acton convinced him to give it some more time.
There were not many other instant messengers at that time, and gradually WhatsApp became popular with the users. The rising popularity of the app enabled the founders to acquire additional venture capital.

The user base of WhatsApp grew steadily over the months and by February 2013, it had around 200 million active users. The rising popularity of WhatsApp grabbed the attention of the social media giant Facebook which acquired WhatsApp for US$ 19 billion in 2014. By 2016 WhatsApp became the most popular messaging application with a user base of one billion.

Awards & Achievements
Jan Koum and Brian Acton were the runners-up at the 8th Annual Crunchies Awards in 2015 in the category Founder of the Year.

Personal Life & Legacy
In 1996, a restraining order was granted against Koum in state court in San Jose. He was accused of verbally and physically threatening an ex-girlfriend. More recently he expressed his regret on having behaved that way.
He lost his mother to cancer in 2000.


Net Worth
Jan Koum has an estimated net worth of US$9.7 billion.

It’s been almost a decade since Brian and I started WhatsApp, and it’s been an amazing journey with some of the best people. But it is time for me to move on. I’ve been blessed to work with such an incredibly small team and see how a crazy amount of focus can produce an app used by so many people all over the world.

I’m leaving at a time when people are using WhatsApp in more ways than I could have imagined. The team is stronger than ever and it’ll continue to do amazing things. I’m taking some time off to do things I enjoy outside of technology, such as collecting rare air-cooled Porsches, working on my cars and playing ultimate frisbee. And I’ll still be cheering WhatsApp on – just from the outside. Thanks to everyone who has made this journey possible.

In response, Facebook CEO Mark Zuckerberg responded to Koum in a comment saying, “Jan: I will miss working so closely with you. I’m grateful for everything you’ve done to help connect the world, and for everything you’ve taught me, including about encryption and its ability to take power from centralized systems and put it back in people’s hands. Those values will always be at the heart of WhatsApp.”

Both Koum and Acton are devout privacy advocates, and both pledged to preserve the sanctity of WhatsApp when they announced its sale to Facebook four years ago, which meant the duo planned never to make integrating the product with a user’s Facebook account mandatory and said it would never share data with the parent company. WhatsApp became entirely end-to-end encrypted in April of 2016, and the company has resisted calls from government agencies to build back doors into its product even for counterterrorism and law enforcement measures.
