The story
DPI was established in 1959 as a regional branch for the IBM corporation. The company operated as a subsidiary until 1981, when IBM's operations in Iran were ceded to the Iranian government. In 2001, DPI became a private company, listed under the Tehran Stock Exchange. Over the company's history, DPI has signed numerous technology-sharing agreements with other software companies, including Mindscape, Dataproducts and Hypercom.
