Quiet money (batch 6): quiet data/AI founders + foreign family-office fortunes

Filling the foreign + data/AI-founder gaps in the quiet-money map.

Quiet data/AI founders (China)

• Liang Wenfeng -> High-Flyer -> DeepSeek - a quiet Chinese quant who turned a GPU-rich hedge fund into a frontier AI lab; the efficient open-weight R1 wave reset the AI-cost/US-China narrative (the same quant-to-data pattern as RenTech/Two Sigma).
• Zhang Yiming -> ByteDance - the reclusive founder of the world's most powerful recommendation-algorithm + behavioral-data company (TikTok/Douyin); stepped back from the spotlight but keeps control; center of the TikTok-ban data fight (Jeffrey Yass a major investor).

Foreign family-office fortunes

• Idan Ofer -> Israel Corp - Israel's richest, from the low-profile Ofer shipping/industry dynasty (ICL chemicals, power, EV bets).
• Anders Holch Povlsen -> Bestseller - Denmark's richest; a quiet major European tech VC (Klarna/Zalando) + Scotland's largest landowner.
• Klaus-Michael Kuehne -> Kuehne+Nagel - reclusive control of the world's largest sea-freight forwarder + Hapag-Lloyd/Lufthansa stakes (critical logistics).
• Guillaume Pousaz -> Checkout.com - the low-profile Swiss founder of a once-$40B payments giant.

US data-marketplace archetype

• Rich Barton -> Zillow (Expedia, Glassdoor) - the "power to the people via data" marketplace model, and its limits (the Zillow Offers iBuying collapse).

Honest limits

Ownership, stakes, and company facts are documented; influence is graded; state-embrace (Liang) and data-security framings (ByteDance/TikTok) are labeled interpretation. The throughline is a method - quiet, concentrated, data-driven capital - not a coordinated plan.
