Our story

In 2005, Calix’s founders, Connor Horley and Mark Sceats, first embarked on the development of a revolutionary idea for a new type of kiln.

It quickly became apparent they were developing a technology that had the potential to be applied across a multitude of industries to help solve some of the world’s greatest challenges.

Through a combination of rigorous research and development, targeted investments and funding, and the ingenuity and passion of a dedicated team, the potential of the company’s core platform technology is beginning to be realised.

From a single application in wastewater treatment, Calix now has 28 patent families covering its core technology, and applications across a range of industrial decarbonisation and environmental solutions.
