About Us

TRIUS, Inc. is a privately held Massachusetts Corporation, formed in 1986 by David A. Schulz and Paris Karahalios in order to provide Consulting Engineering services and to develop inexpensive, high quality software as an alternative to software produced by large, slower-to-move companies, with high overhead. The company started with the development of powerful spreadsheet technology, competing with major players in the late 80's, and 2-D and 3-D Computer Aided Drawing (CAD) technology in the 90's. It eventually moved into the development of GIS and Mapping Technology, producing a numbed of development tools in that area.

Over the years, software products developed by TRIUS, Inc. have been distributed in over 30 countries, in 7 languages, through a number of channels, including retail, shareware, budgetware, direct sales, site licensing, private labels, etc. TRIUS, Inc. has developed and/or published products in the following areas (please, read notes for explanation):
