ACI was founded in Omaha, Nebraska as Applied Communications Inc, in 1975, to develop software for communications applications using the new NonStop computers from Tandem Computers. The founders were James Cody, Dave Willadsen, and Dennis Gates. Chuck Hackett, Charly Foglesong, and Mike May began ACI's relationship with Tandem. Early projects involved building systems to handle ATMs and front ends for core banking systems, which led to the launch of the first product, BASE24, in 1982. BASE24 was coined by a salesman to represent "Baseline Software for 24 hour-per-day system operations".
