who created cash app

Cash App was created inside Square (now Block, Inc.) by a small product team led by Jack Dorsey, with key contributions from Brian Grassadonia and engineer Bob Lee, who helped build the first version in 2013.

Quick Scoop

• Origin: Cash App started in 2013 as “Square Cash,” a peer‑to‑peer money transfer tool built by Square, the payments company co‑founded by Jack Dorsey.

• Key people:
  • Jack Dorsey – co‑founder of Square/Block and driving force behind launching Cash App as a consumer product.

* Brian Grassadonia – senior product/engineering leader credited alongside Dorsey for creating the product.

* Bob Lee – then CTO of Square, widely described as helping create or “founding” Cash App’s original technical implementation.

• Company behind it: Cash App is owned and developed by Block, Inc. (formerly Square, Inc.), not by an independent startup.

Why people get confused

• Some news outlets and obituaries call Bob Lee the “founder” or “creator” of Cash App because he led core engineering work and was CTO at the time.

• Other explainers emphasize Jack Dorsey as the founder, since Cash App was conceived and launched under his company, Square/Block.

So in everyday terms, Cash App was created at Square/Block under Jack Dorsey’s leadership, with Brian Grassadonia and Bob Lee among the main builders.
