Radiator AAA server software was originally developed by Mike McCauley and the Australian company Open System Consultants Pty Ltd. Open System Consultants Pty Ltd and the Finnish Internet engineering company Arch Red Oy joined forces in 2013. They formed a Finnish-Australian company group, which continued developing Radiator-based products and services further.

This year we take an important step in unifying the brands and launching our new company name and brand, Radiator Software. We will use Radiator Software both in Finland and in Australia.  In Finland, Radiator Software is the new official name of Arch Red Oy, while in Australia, Radiator Software is the auxiliary business name of Open System Consultants.
