Atria Software Inc. was a software firm responsible for creating ClearCase during the early 1990s. The company was established on January 11, 1990, by founders including David B Leblang, Paul Levine, David Jabs, among others. Several of Atria's engineers had formerly contributed to DSEE (Domain Software Engineering Environment) while at Apollo Computer. Following Hewlett-Packard's acquisition of Apollo in 1989, these team members departed to launch Atria.
Subsequently, Atria combined with Pure Software to become Pure Atria. This entity later merged with Rational Software, which was then acquired by IBM in 2003. IBM has since maintained development and distribution of ClearCase.
