About
Co-founder of Twitter in 2006, Dorsey pioneered real-time social networking as its first CEO before shifting focus to Block (once Square), expanding Cash App and Bitcoin innovations. In late February 2026, he decisively trimmed Block's staff from over 10,000 to under 6,000, asserting that AI advancements enable leaner teams to outperform larger ones, as evidenced by soaring profits and investor enthusiasm. He anticipates widespread corporate adoption of similar AI-led overhauls within a year. Dorsey fuels Miami's emergence as a crypto hub through advocacy for Bitcoin conferences and support for local digital finance ventures, drawing tech talent to South Florida.
