Kitizin, LLC (formerly Grinz Interactive) is a venture of S. Ross Gohlke, formed to make commercial cloud infrastructure affordable and available for all.

Although Kitizin was formed in 2016, Mr. Gohlke's history of forging practical online solutions for customers stretches back to 1998 when he founded Grinz Interactive; when the internet was still a wild frontier.

The business focus has widened, from providing web development and services in the Grinz era, to cover operating the underlying infrastructure.
