Although he is now a billionaire, Jan Koum wasn't always rich. In fact, his family was struggling financially when they came to the United States as immigrants in 1992.
Jan's mother worked as a babysitter and he worked as a cleaner at a grocery store.
In 1995 Jan bought his first computer and started learning programming.
Three years later he got a job at Yahoo! where he was in charge of security and operations engineering.
Jan worked for Yahoo! for nine years and then he left the job in 2007 to travel the world for one year.
After the year off, Jan and his friend Brian Acton both applied for a job at Facebook and both got rejected.
During February 2009 Jan got an idea to create a mobile app that would make it possible for everyone to communicate with anybody for free, no matter the distance.
So he created the WhatsApp and his friend Brian joined him as a co-founder and helped him to get $250,000 in seed funding.
The founders were very passionate about their product and they did everything they could to make the app work faster and to be more reliable.
They didn't invest any money in advertising. Their company's growth relied only on word-of-mouth marketing.
Given that SMS marketing stats tell us that the mobile messaging marketing is very effective it would be logical that Jan and Brian decided to sell ads in WhatsApp when it became popular, but they did not.
Actually, WhatsApp founders hate ads so they decided not to monetize their app through ads, but to charge their users a $1 per year fee.
After five years of hard work WhatsApp had over 450 million monthly active users, so they got attention from some of the biggest tech companies in the US.
Mark Zuckerberg, the founder of Facebook, invited Jan Koum one night to a dinner and offered him to buy his app.
Just a few days later, it was revealed that Facebook will buy WhatsApp for $19 billion!
At the time, Jan Koum owned 45% of WhatsApp, so he got around $8 billion.
His current wealth is estimated at $11.5 billion in 2022.

The founder of WhatsApp, Jan Koum, lives in Mountain View, California, but photos of his house are not available to the public.
Jan Koum is a collector of rare Porsches. He has more than ten Porsches, but he also has some other cars, like Ferrari F12tdf which has a V12 engine and costs over $500,000!
Here is what Jan said in an interview while talking about his Ferraris:
I feel like Ferrari is my Italian mistress. When I drive a Ferrari I feel like I'm cheating on my other cars.
Jan Koum has no tattoos.
Do one thing, and do it well. I only have one idea, that is WhatsApp, and I am going to continue to focus on that. I have no plans to build any other ideas.
Be simple and reliable.
Communication is at the very core of our society. That’s what makes us human.
The F-word here is focus.
Marketing and press kicks up dust. It gets in your eye, and then you’re not focusing on the product.
We’ve taken SMS technology for consumers and improved it.
It was so run-down that our school didn't even have an inside bathroom. Imagine the Ukrainian winter, -20°C, where little kids have to stroll across the parking lot to use the bathroom. ...I didn't have a computer until I was 19–but I did have an abacus.
I grew up in a country where advertising doesn’t exist.
It’s not hard to sell a company, but if you look at [leading online] companies today like Facebook, Google, Yahoo and Twitter, they didn’t sell. They stuck around and built a great offering for users.
I grew up in Russia. We had a telephone line, but a load of our neighbours didn't. It became a shared resource for the whole apartment complex. People would come and knock on the door and ask to call their family in another city.
A lot of what I experienced growing up in the U.S.S.R. and coming to the U.S. as an immigrant actually reflects itself in WhatsApp. Experiences from our youth shape what we do later in life.
We focus a lot on the quality of experience, speed, reliability. It’s not sexy from a lot of people’s perspective, it’s not glitzy in the feature set, but it’s what people come to rely on.
Advertising isn't just the disruption of aesthetics, the insults to your intelligence and the interruption of your train of thought. At every company that sells ads, a significant portion of their engineering team spends their day tuning data mining, writing better code to collect all your personal data.
There were a lot of negatives, of course, but there were positives to living life unfettered by possessions. It gave us the chance to focus on education, which was very important in the Soviet Union.
No one wakes up excited to see more advertising, no one goes to sleep thinking about the ads they’ll see tomorrow.
I feel like Ferrari is my Italian mistress. When I drive a Ferrari I feel like I'm cheating on my other cars.
If you run a startup and your goal is to get on techcrunch, you are doing it wrong.
We’re the most atypical Silicon Valley company you’ll come across. We were founded by thirty-somethings; we focused on business sustainability and revenue rather than getting big fast, we’ve been incognito almost all the time, we’re mobile first, and we’re global first.
The message growth rate in Brazil – it’s not like a hockey stick: it’s like a vertical line.
Advertising has us chasing cars and clothes, working jobs we hate so we can buy sh*t we don't need.
Our team has always believed that neither cost and distance should ever prevent people from connecting with their loved ones, and won’t rest until everyone, everywhere is empowered with that opportunity.
A lot of times, people start out with a lot of good ideas, but then they don’t execute. They lose the purity of their vision. You end up running around in circles.
Build a sustainable company that’s here for the next 100 years.
