Block, Inc. (NYSE: SQ), formerly known as Square, Inc., has undergone a remarkable transformation since its inception in 2009.

This article explores Block’s origins, growth, product evolution, market impact, and future outlook as it solidifies its position as a fintech powerhouse.

Foundation and Early Vision

Block’s origin story is rooted in a simple but powerful insight. Co-founder Jim McKelvey, a glass artist, lost a sale because he could not accept credit card payments. This experience exposed a glaring gap: many small businesses and individual sellers were excluded from the digital economy due to high costs and complexity of traditional merchant services.

Partnering with Jack Dorsey—co-founder of Twitter—the duo launched Square, Inc. in February 2009. Their mission was clear: democratize financial services by creating an accessible, affordable mobile payment system. The breakthrough came in the form of the Square Reader—a compact card reader that plugged into smartphones—turning any mobile device into a point-of-sale (POS) terminal.

This innovation opened the door for millions of small merchants, enabling seamless credit card acceptance without the need for expensive equipment or contracts. Square’s transparent flat-rate fee model replaced confusing pricing structures, building trust and adoption.
