DDC-I, Inc. is a privately held company providing software development of real-time operating systems, software development tools, and software services for safety-critical embedded applications, headquartered in Phoenix, Arizona. It was first created in 1985 as the Danish firm DDC International A/S (also known as DDC-I A/S), a commercial outgrowth of Dansk Datamatik Center, a Danish software research and development organization of the 1980s. The American subsidiary was created in 1986. For many years, the firm specialized in language compilers for the programming language Ada. In 2003, the Danish office was closed and all operations moved to the Phoenix location.
