John Sampson is a seasoned public policy leader with 35 years of Capitol Hill and Washington advocacy experience and 14 years directing technology-government engagement for Microsoft and now Workday. He combines deep political acumen—built advising House leadership and managing relationships with multiple CEOs—with hands-on technical literacy, having contributed to front-end work on notable open-source projects like the Brave browser and the Sizzle selector engine. Known for translating complex technology trends (notably generative AI) into actionable policy, he has run cross-functional teams that span engineering, legal, and communications to seize strategic opportunities. Equally comfortable briefing executives and legislators, he has a track record of forging long-term, high-impact partnerships and turning “big-bet” initiatives into measurable results.
