4 Ukrainian Jews Become Among the Richest Immigrants to the US According to Forbes

How did four Ukrainian Jews — Jan Koum, Leonid Radvinsky, Michael Polsky and Max Levchin — go from childhood in Kyiv, Odesa and the Kharkiv region to a combined net worth of over $25 billion in the United States?

Each of them founded or led a world‑class company: Jan Koum was one of the creators of WhatsApp, Leonid Radvinsky turned OnlyFans into a global phenomenon, Michael Polsky founded Invenergy LLC in the “green” energy sector, and Max Levchin co‑founded PayPal and now runs Affirm.

This is reported in a publication by Forbes. By the number of billionaire immigrants, Ukraine ranked 9th among 41 countries.

From Kyiv’s Courtyards to Global Heights

How Their Stories Began in Ukraine

• Jan Koum was born in February 1976 on the outskirts of Kyiv. In the family of an electronics engineer there were no trendy computers, but there were radios that the boy would take apart and reassemble. In a school BASIC club he wrote his first programs to send text messages over a local network.
• Leonid Radvinsky was born in the early 1970s in Odesa, near the famous Privoz Market. Together with his mother he sold souvenirs to tourists, calculating profit and bargaining for every dollar. These lessons in commerce and the ability to connect with people laid the foundation for his entrepreneurial drive.
• Michael Polsky was born in 1947 in a rural area of the Kharkiv region. In his free time he built wind turbine models from bicycle spokes and tin cans, dreaming of an energy future. After technical college he worked at a power plant, where he first encountered the ideas of alternative energy.
• Max Levchin was born in July 1975 in Kyiv into a family of historians. At school he became passionate about chess and the Pascal programming language. By organizing a “Young Programmer” club, Max not only deepened his algorithmic knowledge but also learned to share expertise and build teamwork.

In the Emigration Lab — A Step West

Each of them took the risk to leave their homeland and go to the United States with minimal resources:

1. Jan Koum arrived in 1992 with his mother and grandmother under a repatriation program. For the first years he worked as a cleaner and barista to pay for his studies at San Jose State University.
2. Leonid Radvinsky settled in Chicago on a humanitarian visa, graduated from Northwestern University, and began working in internet marketing.
3. Michael Polsky was invited as an energy specialist in 1976. With $500 in his pocket, he got a job as an electrician, and twenty years later founded his own company, Invenergy.
4. Max Levchin obtained political asylum in 1991, moved to Memphis, and by the end of the decade had co‑founded PayPal.

Breakthroughs and Achievements

• WhatsApp by Jan Koum and Brian Acton amassed over 2 billion users in a few years, and its sale to Meta netted Koum over $16.9 billion.
• OnlyFans by Leonid Radvinsky became a platform generating over $1.3 billion in annual revenue and awarded him personal dividends of over $1 billion.
• Invenergy by Michael Polsky executed projects worth more than $7 billion, including wind and solar farms across America.
