Jack Dorsey
Jack Dorsey is a technology entrepreneur and co-founder of Twitter and Square, currently serving as Head (Principal Executive Officer) of Block, Inc., the payments and financial services company Square rebranded to in December 2021. He is best known for co-creating Twitter and for championing Bitcoin adoption in mainstream commerce, including pioneering Bitcoin trading at Square as a public company in 2017 before any regulatory playbook existed. At Block, he has continued to push Bitcoin integration — enabling Lightning Network payments for merchants via Square terminals — while undertaking significant organizational restructuring in 2026 to flatten management layers and pivot the company toward artificial intelligence and agentic workflows.
