Mike Devlin is a U.S. entrepreneur who co-founded Lexington, Massachusetts-based Rational Software Corporation, a software development company.
Devlin studied electrical engineering and computer science at the United States Air Force Academy, graduating in 1977, before completing an M.S. in computer science the following year at Stanford University.
As CEO of Rational, Devlin oversaw the acquisition of several companies, including Objectory AB (1995), and Catapulse (2001), a start-up which was funded by Rational, in conjunction with Benchmark Capital.
In 2003, Rational Software was acquired by IBM for 2.1 billion dollars (U.S), a move that saw Devlin become general manager with IBM. He retired from the company two years later.
