Compuware Corporation is an American software company with products aimed at the information technology (IT) departments of large businesses.

The company has its headquarters in Downtown Detroit, Michigan. In December 2014, Compuware was acquired by private equity firm Thoma Bravo and became a privately held company. In 1973, Peter Karmanos, Jr., Thomas Thewes, and Allen B. Cutting established Compuware Corporation. Their vision was to help people do things with computers by providing their clients with professional technical services, allowing them to focus on their own core businesses. In 1977, Compuware introduced Abend-AID, its first software product. Designed to detect bugs and suggest corrective action in corporate IBM mainframe systems. The release of Abend-AID established a product strategy for Compuware, alleviating the peaks and valleys of revenue that occur in the services business. By 1978, Compuware opened its first remote office to service the Washington, D.C. and Baltimore area.
