It's the sticker that Jan Koum has on her desk for a long time, but who is Jan Koum? He is the creator of the most famous App in the world, WhatsApp.
An immigrant from the United States, he is originally from Ukraine and since 1992 he moved to California, North America, together with his mother and grandmother.
He started out working as a cleaning staff at a grocery store, but his creation would change his future forever. Koum is the co-founder and CEO of WhatsApp, a revolutionary application. Facebook Inc. acquired WhatsApp in 2014 for $ 19 billion USD, making Koum a very, very successful man.
It is what we want from immigrants, to be successful in the US, without ads, without games, without tricks.
