PAYMENTS
Jack Dorsey, the co-founder of Twitter and CEO of Block Inc. has built a fintech empire with a net worth estimated at US $ 4bn in 2025. His ventures range from social media to business payments, while consistently advocating for opensource, decentralised solutions that challenge traditional financial infrastructure. The 48-year-old entrepreneur’ s most significant contribution to the fintech sector comes through Block Inc., the company that has redefined merchant services and consumer payments.
Beyond his earlier work with Twitter, Dorsey’ s fintech endeavours have positioned him as a Bitcoin maximalist whose technical vision extends far beyond conventional payment processing into cryptocurrency infrastructure and mining hardware.

Building the foundation: Square’ s evolution into Block Founded in 2009, Square began as a point-of-sale system enabling merchants to accept card payments and manage operations including inventory, payroll and business loans. The platform now serves over four million sellers and processes US $ 241bn annually as of 2024, transforming from a simple card reader into a comprehensive business ecosystem.
In December 2021, Dorsey officially changed the company name from Square to Block Inc., reflecting his growing interest in blockchain technology and the need for a name that better encompassed the various businesses beyond merchant payment services. This rebranding signalled a strategic pivot towards Bitcoin integration across all company subsidiaries.
The timing proved prescient. Block joined the S & P 500 in July 2025, marking a symbolic milestone that placed the digital finance firm under Wall Street’ s spotlight. The company’ s portfolio now includes Cash App, Afterpay, TIDAL, Bitkey hardware wallet and the newly launched Proto mining division, each contributing to Block’ s comprehensive fintech offering.
Today, Block maintains 8,584 BTC on its balance sheet valued at nearly US $ 1bn, with an average purchase price of US $ 30,405 per bitcoin. This substantial Bitcoin holding reflects Dorsey’ s conviction that cryptocurrency will play a central role in future financial systems.
