Company Description

It all started with an idea at Block in 2013.

We want to redefine the world’s relationship with money to make it more relatable, instantly available, and universally accessible.

Today, Cash App has thousands of employees working globally across office and remote locations, with a culture geared toward innovation, collaboration and impact.

No matter the location, we tailor our experience to ensure our employees are creative, productive, and happy.
