Background info on the purchase of Brightbill-Roberts to IQ software:  http://martinmanor.com/iqtech.htm
which stated:

In 1993, while working as a computer consultant, I wanted to produce a diskette distributable, desktop presentation of my consulting services. A brochure on a disk. In the past, I had used an application called "Show Partner F/X". Limitations in the version I had caused me to seek an upgrade. After much difficulty I located the publisher, Brightbill-Roberts & Company, in Syracuse, N.Y. My whole experience purchasing this upgrade indicated that the company was in decline. I wrote and expressed my disappointment with the thought of this marvelous desktop presentation platform disappearing from the marketplace, and, asked if they would be interested in selling me the rights.

They responded immediately with an offer. I contacted an old friend of mine, Earl "Ace" Starry, who had recently received his masters degree in business and marketing. We negotiated for a few months then flew to Syracuse in January of 1994 and bought all of the company's assets. In addition to Show Partner, we purchased an object oriented desktop development platform called "HyperPAD".

Soon after we knew we were going into the software publishing business, I contacted another old friend, Mark Kroenecke, who has a degree in electronics, to fill the role of Chief Technical Officer. A friend of Ace's, Scott Hamilton, an M.B.A. in finance, signed-on as our Chief Financial Officer. Finally, we were referred to Tim Hagan, an attorney with a strong background in finance who came on board as Chief Legal Council. With this core group, IQ Technologies, Inc. was born.
