BMC Software, Inc. (NASDAQ: BMC) is a multinational corporation specializing in Business Service Management (BSM) software. Headquartered in Houston, Texas, BMC develops, markets and sells software used for multiple functions, including IT service management, data center automation, performance management, virtualization lifecycle management and cloud computing management. The name "BMC" is taken from the surnames of its three founders—Scott Boulette, John Moores, and Dan Cloer.

Employing over 6,000, BMC is often credited with pioneering the BSM concept as a way to help better align IT operations with business needs. For 2011, the company recorded an annual revenue of $2.1 billion, making it the #20 largest software company in terms of revenue for that year.

During the late 1970s, BMC Software founders Scott Boulette, John Moores, and Dan Cloer began a contract programming partnership. All three had worked at Shell Oil doing computer programming. By 1980, the company was incorporated in the state of Texas and officially became BMC Software. Moores was the company's first CEO. The firm primarily wrote software for IBM mainframe computers, the industry standard at the time. Sometimes BMC wrangled with IBM about issues such as "software tie-in claims."
