The co-founder and former CEO of WhatsApp, Jan Koum, is now associated with Feadship's latest 100.7-metre Moonrise, delivered in 2025. Built as the successor to his original 99.9-metre yacht of the same name (the Feadship superyacht Moonrise delivered in 2020), the new build retains Studio de Voogt's sleek exterior styling and interiors by Rémi Tessier, while incorporating numerous technological refinements, including integrated Starlink receivers in place of traditional satellite domes.
Other updates include a taller mast, enlarged exterior decks and swim platform, a massage area, gym and hair salon on the sundeck, and improved acoustic performance achieved through redesigned propellers, appendages and resilient-mounted anchor winches.
Following delivery of the new Moonrise, Koum's original 100-metre yacht entered the brokerage market and was sold in July 2026.
