Intergraph Corporation 

Though Silicon Valley may be the epicenter of tech companies today, one of the earliest developers of hardware and software got its start in Huntsville. Intergraph Corporation was founded in 1969 by former IBM employees who worked with NASA and the Army to develop systems to apply digital computing to missile guidance. By 2000, Intergraph was focusing exclusively on software and by 2008 was one of the world’s largest software companies. The company was acquired in 2010 by Hexagon AB, a global technology group based in Sweden.
