Meet our team
We are geeks who love playing with new technologies and sharing experience

Hi there! We are Handsoncode. When we started in 2012 we had no idea that this spreadsheet project would become so popular. Since it happened, complexity followed popularity. In 2014 we revised the structure of Handsontable and decided to make it modular. This allowed us to introduce new commercial features built on top of the free and open-source core.

Ultimately, we aim to create a 60FPS composite spreadsheet framework which works without limitation in performance, regardless of the size of the data set.
