Note: The 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.
