Jan Koum (b. 1976) was born in Kiev, Ukraine. When he was 16 years old he moved to California with his mother, having experienced enough anti-Semitism and political turnovers. (His father intended to join them eventually, but passed away several years later before he could do so.) The two survived on food stamps and a subsidized two-bedroom apartment. Koum swept floors at a supermarket to make ends meet. At 18, he started learning programming by himself from a set of used books before enrolling at San Jose University. Soon, he got a job working with computers at Ernst & Young, one of the world’s Big Four auditing companies. By 21, Koum had dropped out of school and was hired by Yahoo to work in its infrastructure engineering. After nine years with the company, Koum quit to do some travelling with fellow employee Brian Acton. Upon returning from their trip, the two applied to work for Facebook, but were turned down. Instead, Koum started thinking about a new iPhone messaging app, inspired by how difficult and expensive it was for him to keep in touch with family in Russia and Ukraine (as well as memories of how his parents avoided using a phone in the Soviet Union for fear of being listened to). The following month, he incorporated WhatsApp Inc. Brian Acton later worked together with Koum to make his vision a reality, together with friend Alex Fishman. WhatsApp became hugely popular very quickly, and became the world’s most popular messaging app. In 2014, Koum’s friend Mark Zuckerberg bought out WhatsApp for $19 billion. This thrust Koum onto Forbes list of the world’s richest people. With his net worth now close to $9 billion, he is among the Top 10 richest US immigrants. Meanwhile, WhatsApp expanded to offer voice calls and document-sharing, became completely free (with no advertising), and now has over 1 billion users worldwide. Yesterday, they launched a new form of encryption, making WhatsApp among the most secure forms of communication available to the public. Koum continues to work on WhatsApp, and on the board of Facebook, and has donated hundreds of millions of dollars to charity. He is also a founding member of San Francisco’s JFE – Jews for Entrepreneurship – an organization that provides opportunities for young Jewish entrepreneurs in the high tech sector.
Words of the Week
From religion comes a man’s purpose; from science, his power to achieve it. Sometimes people ask if religion and science are not opposed to one another. They are: in the sense that the thumb and fingers of my hand are opposed to one another. It is an opposition by means of which anything can be grasped.
