Careers at ACI Worldwide


ACI Worldwide’s mission is to deliver universal payment solutions that provide control, choice and flexibility to its customers while maintaining their peace of mind.

Business segments

ACI Worldwide is a payment systems company.  The firm operates three reportable business segments based on geography:  the Americas, EMEA (Europe/Middle East/Africa), and Asia-Pacific.

Founding story

In 1975 Dave Willadsen, Dennis Gates, and James Cody founded Applied Communications Inc. (ACI for short) in Omaha, Nebraska. The company’s purpose was to develop software for NonStop server computers used by banks and stock exchanges. Initial projects involved developing solutions to handle ATMs and other banking systems that required high uptimes.

In 1981 ACI obtained its first foreign client, an Australian bank. In 1982 it released its first official product, BASE24, short for “Baseline Software for 24 hour-per-day system operations". Over the next few years the product began handling service transactions from POS terminals and branch systems. The company also began developing solutions for functions as such settlement and fraud detection.

Due to its success, hardware suppliers such as HP, Sun Microsystems, IBM, and Stratus began supporting ACI’s software. This in turn led to an increase in wire transfers, wholesale banking payments, and automated clearing house transactions. ACI grew significantly, and by 1986 it had 131 clients in 14 countries, as well as sales offices and partners worldwide.

In 1995 ACI went public and began trading on the NASDAQ uner the name Transaction Systems Architects (TSA). In the early 2000s it began supporting card and merchant management, retailer solutions, and online banking. In 2007 its corporate name was changed from TSA to ACI Worldwide (ACIW). In 2012 its services extended to governments, education institutions, and charities.
