About us

Hi, I am Henri Chen, Co-Founder of Potix Corporation.

My team and I developed ZK Spreadsheet -- one of the very first embeddable web spreadsheet components. It is trusted by Citigroup, Adobe, Nokia and more.

For 10 years, we have improved it to keep up with the ever-growing data of users like finance professionals, analysts, researchers and scientists. It was not until 2 years ago, we decided to rewrite everything. With a whole new architecture designed specifically for big data.
