RSi was founded by Rand Mark Manasse in 1979, long before the personal computer revolution began. In the beginning, our services focused on the needs of middle market companies who had invested in Data General hardware and software. In those days, we supported distributor's and end-user's sites running minicomputer software from MCBA.

As the personal computer marketplace developed, RSi expanded into this area, building relationships with business applications leaders like Macola Software, Great Plains Software, Novell and Microsoft.  To help bring the personal computer marketplace to the average business, high quality networks needed to be installed and therefore network hardware companies like Hewlett-Packard, Compaq and others were developed. Over the years, our firm has installed business solutions in over 600 companies.

Today, the RSi Staff offer a unique breadth of business expertise and systems knowledge. Our "off-the-shelf" core business offerings, Great Plains Dynamics and Macola Progression Series and their associated suite of independently developed integrated electronic commerce, service, bar coding, job costing applications and more provide the backbone for automating middle market businesses from $5-500 million.
