Jack Dorsey (Fintech / Payments) at Block (Square) — San Francisco, United States

Jack Dorsey co-founded both Twitter and Square (now Block) in the same year, 2006, making him one of the rare two-time founders to build multi-billion-dollar companies simultaneously. At Block, he champions Bitcoin and financial inclusion for the unbanked. His stripped-down leadership style, meditation practice, and public advocacy for Bitcoin maximalism make him one of tech's most philosophically distinct founders.
