Co-founder and former CEO of WhatsApp; technology investor. Net worth ~$16.9–17B. Immigrant success story — arrived in the U.S. at 16, worked as a grocery-store cleaner, built WhatsApp to 450M users, sold to Facebook for ~$19–22B in 2014. Atherton compound assembled over four years (~$100M+, plus a museum for 100+ Porsches). ~$200M Malibu real estate, $125M Beverly Hills mansion, ~$70M Château de la Garoupe in Cap d'Antibes (Nov 2023). Newlands VC family office (Dallas, $10B AUM).
Fleet of three Gulfstream G650ERs: N143 (A0ADD4, S/N 6538, 2023), N158 (A0E7E6, S/N 6307, 2017) and N518KA (A68009). All are held by TVPX Aircraft Solutions Inc as trustee — an anonymising owner trust, so the FAA registry names no individual and the attribution to Koum rests on reporting rather than on the registration itself. One tracked direct from UAE. Expected: heavy NorCal↔SoCal↔Antibes↔Miami corridor plus international. Owns superyacht *Moonrise* (262 ft, ~$170M).
Left Facebook/WhatsApp in 2018 over data privacy and monetization disputes.
Note · Celebplanes tracks Jan Koum's registered aircraft — not Jan Koum personally. ADS-B data shows when and where the plane moved; who was aboard any given flight is unknown.
