About Grid

Building the future of spreadsheets

Spreadsheets run the world — and we run spreadsheets. Spreadsheets hold more business logic than any other system, driving critical decisions in finance, operations, and strategy. Yet, integrating spreadsheet logic into modern applications has traditionally required complex, custom development. We’re here to change that.

We’ve developed one of the most advanced independent spreadsheet engines—capable of complex calculations, interactive data visualizations, and seamless integration with AI-driven applications. Founded in Reykjavík in 2018, we’re on a mission to redefine the future of spreadsheets.

The GRID spreadsheet engine also powers Calculator Studio–our SaaS platform that enables users to convert spreadsheets into interactive calculators through an easy-to-use WYSIWYG editor. We believe spreadsheets should do more than crunch numbers; they should be a launchpad for innovation.
