Atria Software Inc. was a software company that developed ClearCase in the early 1990s.[1] It was founded by David B Leblang,[2] Paul Levine,[3] David Jabs[4] and others on January 11, 1990.[5] Some of the Atria developers had worked on an earlier system: DSEE (Domain Software Engineering Environment) from Apollo Computer. After Hewlett-Packard bought Apollo Computer in 1989, they left to form Atria.[6][7][8] Atria later merged with Pure Software to form Pure Atria.[9] That firm merged with Rational Software, which was purchased by IBM in 2003.[10] IBM continues to develop and market ClearCase.
