Jan Koum | Mogambo

The name Jan Koum might not sound familiar, but the app he was a CEO of is gaining popularity recently—WhatsApp. The app has gained notoriety in recent months for updating its privacy policies, making people fearful of having their data exposed to others. Jan entered the Forbes list of wealthiest people in 2014 after having $7.5 billion in net worth. He dislikes the title entrepreneur because business people, to him, are often driven by money, while he is not—he just wants to create useful products. He also is an active donor for various causes.

The WhatsApp co-founder is the owner of a 241.3-feet yacht that could accommodate up to 12 guests, excluding the 20-man crew. The vessel was built in 2012, with the exterior and interior designed by Reymond Langton Design.  Guests and family members can enjoy various amenities like a spa, a gym, an elevator, and a deck Jacuzzi.
