Virtualmin was founded by Jamie Cameron and Joe Cooper in 2005. We provide virtual host administration products based on Webmin - the world's most popular web-based UNIX and Linux system administration tool, with over 3 million downloads every year.
As open source developers, we've been working on solving real systems management problems for two decades and written over a half million lines of code in the process. Jamie created Virtualmin, Webmin and Usermin, as well as authored the Bruce Perens' Open Source Series book titled Managing Linux Systems with Webmin: System Administration and Module Development (Prentice Hall PTR, 2003). Joe wrote The Book of Webmin: Or How I Learned to Stop Worrying and Love UNIX (No Starch Press, 2003) and founded Swell Technology LLC, an open source-based web-caching appliance vendor in operation from 1999 to 2005. It is merely an eerie coincidence that both of our initials are "JC".
Virtualmin is in use by more than a thousand hosting providers worldwide. Webmin is the world's most popular web-based system administration tool, and is used by RackSpace.com, Hosting.com, Lycos Europe, University of Texas, and thousands of other companies and individuals world-wide.
In 2007, Virtualmin accepted funding from Y Combinator and became a Delaware Corporation.
In 2009, we announced Cloudmin, a cloud computing management UI and platform for development of cloud computing services.
In short, Virtualmin is four guys (Eric Andreychek joined us in 2008 and Ilia Rostovtsev joined us in 2014) trying to tackle really big problems in hosting and cloud computing management.
