Sergey Brin
Director1 list appearance
Inside Google and Alphabet, Brin directed moonshot division Google X and served as President of Alphabet until December 3, 2019, when he and Page stepped down from formal executive titles while retaining super-voting board control. Following the generative AI inflection point in 2023, Brin famously came out of semi-retirement to work hands-on alongside Google DeepMind engineers in Mountain View. Across 2025 and 2026, Brin's operational influence surged: he pushed a 60-hour-week engineering culture, backed the August 2026 reorganization of Google DeepMind that elevated Koray Kavukcuoglu to run day-to-day AI execution, and spearheaded the "recursive self-improvement" (RSI) push behind Google's October 2026 release of **Gemini 4 Argon**. Simultaneously in 2026, Brin executed a high-profile political and geographic pivot—joining President Donald Trump's PCAST in March, accepting the National Medal of Science at the White House in October, relocating his residency from California to Lake Tahoe, Nevada, and spending over $100 million as the #1 financial backer of the successful November 2026 campaign to defeat California's Proposition 40 billionaire wealth tax.
