# Jan Koum

> Jan Koum is the Ukrainian-born co-founder of WhatsApp who built one of the world's most-used messaging platforms on a foundation of radical privacy and zero advertising — then sold it to Facebook for $19.3 billion in 2014. A self-taught programmer who arrived in the US at 16 on food stamps, Koum's journey from a Soviet surveillance state to the pinnacle of Silicon Valley is one of the most unlikely origin stories in tech. He left WhatsApp in 2018 rather than compromise its privacy principles, and now runs Newlands, a secretive investment firm, while giving billions through the Koum Family Foundation.
