Jan Koum is a Ukrainian-born American entrepreneur who co-founded the messaging app WhatsApp, which he sold to Facebook in 2014 for approximately $19 billion. He is reported by multiple yacht-industry publications and news outlets to be the owner of the 99.9m Feadship superyacht Moonrise, delivered in 2020, though as with many superyachts ownership is typically structured through corporate entities rather than held in the individual's name directly.
