Row Zero

Cloud spreadsheet that keeps sensitive data server-side while giving analysts familiar self-serve tools.

Row Zero is a spreadsheet built for big, sensitive datasets: data stays in the cloud under governance instead of scattering across laptops as CSV exports, while users keep a familiar spreadsheet interface with the scale to handle billions of rows. It suits data teams balancing self-serve analytics with data security. The company was founded in 2021.
