David Sacks is an American technology entrepreneur and venture capitalist, known as a member of the 'PayPal Mafia,' co-founder of Yammer, and general partner at Craft Ventures. He has no parliamentary record as he has not served in any legislative body. The United States does not have a parliament; it has a Congress. Sacks has not served in the U.S. Congress (House of Representatives or Senate), nor in any state legislature. His public record consists primarily of corporate filings, SEC documents related to companies he founded or invested in, podcast appearances (All-In Podcast), and political donations/advocacy rather than any legislative service.
