Linuxgruven

Linuxgruven was a technical services firm that was designed to specialize in work with the Linux Operating System. The firm was officially incorporated in the state of Missouri in February 2000, by founders James Hibbits and Michael Lebb. Its doors closed on March 8, 2001. Linuxgruven had offices in eight U.S. cities including a headquarters office in Clayton, Missouri, which is a St. Louis, Missouri suburb. At its peak the company employed 106 people.

This "company" was actually a scam operation offering classes costing at least $2.000 for people to become Linux Certified Professionals. They saw the popularity of the Linux Operating System being an open-source alternative to Windows and Macintosh and seized the moment to make a huge amount of profit from people who would realize no real gain from their certification.
