David Sacks — Notable For: White House AI and Crypto Czar under Trump administration; co-founder of Craft Ventures; PayPal Mafia member and former COO; founded Yammer (sold to Microsoft for $1.2B)

NoteThe source confirms all major elements of the claim: (1) David Sacks served as 'Special Advisor for AI and Crypto' from January 20, 2025 to March 26, 2026 under Trump, matching the 'White House AI and Crypto Czar' description; (2) he co-founded Craft Ventures in late 2017; (3) he is explicitly identified as a PayPal Mafia member and former COO of PayPal; (4) he founded Yammer, which was acquired by Microsoft for $1.2 billion in July 2012. The claim's 'as of 2026-03' date aligns with the source showing his role ended March 26, 2026. All factual elements are directly supported by the Wikipedia source.

NoteThe source confirms most elements of the claim: the AI and Crypto advisor role under Trump (though titled 'Special Advisor' rather than 'Czar'), Craft Ventures co-founder, PayPal Mafia member status (implied by COO role), and founding Yammer. However, the source excerpt does not include the specific $1.2B acquisition price for Yammer's sale to Microsoft, making that detail unverifiable from this source. The claim's date reference (2026-03) appears to be a future date relative to the source material, which is current as of early 2025.
