Overview

Mantissa Corporation is an American software company that specializes in the development of software for the management of data centers. It is headquartered in Birmingham, Alabama, in the United States, and maintains a subsidiary in Great Britain as well as distribution agents in Norway, South Africa, Singapore, South Korea, and Japan. The company was founded in June 1980. The following year it launched its first product, an automated system for the distribution of reports within data center environments, which the company considered to be the first such system available on the market. Since then, later versions of this system have formed the basis of Mantissa Corporation's product line, while that line has evolved to include other related products that have been updated and adapted for PC and Web environments. Mantissa's product portfolio has historically centered on output management and report management. Its Advanced Output Management (AOM) offering and its Report Management System (RMS) family — including RMS/Basic, RMS/Online, RMS/Spool, RMS/Desktop, and RMS/Webaccess — address the capture, distribution, and delivery of mainframe and distributed report output. The company has also offered Advanced Systems Operation (ASO) tools such as JOB/Master, JCL/Master, RUN/Master, and CONSOLE/Master, aimed at job and console management in large systems environments. More recently, Mantissa has marketed iDovos, an identity management product positioned around preventing identity theft and identity fraud, and z86VM, a virtualization-related offering. The company acquired Software Integration Strategies in 1989. Mantissa has been referenced in industry contexts including the REXX Symposium, the Alabama Information Technology Association, and IBM's list of independent software vendors, and its iDovos product generated press attention in the late 2000s for its claims about identity theft prevention.

History

Mantissa Corporation was founded in June 1980 in the United States. In 1981, the company launched its first product, an automated system for the distribution of reports within data center environments. According to the company, this was the first such system available on the market. That product became the foundation of Mantissa's product line, and subsequent versions evolved to include related products adapted for PC and Web environments. In 1989, Mantissa acquired Software Integration Strategies, expanding its capabilities in the data center software space. Over the following decades, the company developed and marketed a range of output management and report management products, including Advanced Output Management (AOM) and the Report Management System (RMS) family (RMS/Basic, RMS/Online, RMS/Spool, RMS/Desktop, RMS/Webaccess). It also offered Advanced Systems Operation (ASO) tools such as JOB/Master, JCL/Master, RUN/Master, and CONSOLE/Master. Mantissa established a subsidiary in Great Britain and maintained distribution agents in Norway, South Africa, Singapore, South Korea, and Japan, giving it an international presence in enterprise software markets. In the late 2000s, the company introduced iDovos, an identity management product aimed at preventing identity theft and identity fraud, which attracted attention in industry press and at events such as the e-Crime Congress and the American Banker's Identity Theft and Fraud Symposium. The company also developed z86VM, a virtualization-related offering. Mantissa has been listed as an independent software vendor in IBM's vendor directory and has been associated with the Alabama Information Technology Association and the REXX Symposium.
