Jack Dorsey

Jack Dorsey co-founded Square in 2009 (renamed Block in 2021) and serves as the company's guiding force as chairman of the board, with day-to-day operations led by the management team. Block operates multiple businesses: Square (payment processing hardware and software for merchants), Cash App (a peer-to-peer payment and personal finance app with over 50 million monthly active users), Afterpay (buy-now-pay-later acquired in 2022), TIDAL (music streaming), and Bitkey/Proto (Bitcoin mining hardware). Dorsey's strategic vision for Block centers on two core beliefs: that small businesses deserve the same technology tools as large enterprises (Square's mission), and that Bitcoin will become the native currency of the internet (hence the company's name "Block" referencing blockchain). Cash App has become Block's fastest-growing and most valuable asset, evolving from simple P2P payments into a comprehensive financial services platform offering direct deposit, investing, and Bitcoin trading for younger Americans. Key decisions involve Cash App monetization and banking feature expansion, Square merchant ecosystem growth, Afterpay integration across the Block ecosystem, Bitcoin strategy (Block holds significant Bitcoin on its balance sheet), and overall profitability trajectory.
