Intergraph Corporation was a U.S.-based software development and services firm that is currently a subsidiary of Hexagon AB. It provides enterprise engineering and geospatial software solutions globally through three primary business units: Hexagon Asset Lifecycle Intelligence (ALI, previously known as PPM), Hexagon Safety & Infrastructure, and Hexagon Geospatial. The company’s headquarters are located in Huntsville, Alabama, United States.

In 2008, Intergraph ranked within the top 100 software companies worldwide by revenue. It became part of Hexagon AB following an acquisition in July 2010.

History

Established in 1969 under the name M&S Computing, Inc. by former IBM engineers Jim Meadlock, Nancy Meadlock, Terry Schansman, Keith Schonrock, and Robert Thurber—who had backgrounds working with NASA and the U.S. Army on digital missile guidance systems—the company adopted the name Intergraph Corporation in 1980.

Intergraph specialized in developing workstations utilizing the Clipper architecture from Fairchild Semiconductor and created a proprietary UNIX operating system variant called CLIX. In 1987, the company acquired Fairchild’s Clipper division.

Beginning in 1997, Intergraph initiated patent infringement lawsuits targeting major hardware vendors such as Intel, HP, Texas Instruments, and Gateway, Inc., based on intellectual property related to Clipper technology. These legal actions resulted in settlements exceeding $394 million. By the year 2000, Intergraph withdrew from hardware production to concentrate solely on software development, divesting its graphics accelerator segment to 3Dlabs and its workstation/server businesses to Silicon Graphics.

In 2006, Intergraph was taken private through acquisition by private equity firms Hellman & Friedman LLC, Texas Pacific Group, and JMI Equity. Four years later, in 2010, it re-entered the public sphere via purchase by Hexagon AB.

Post-acquisition, Hexagon restructured its geospatial holdings: management of ERDAS, Inc. was integrated under Intergraph’s oversight while Z/I Imaging airborne sensor operations were transferred to Leica Geosystems. In December 2013, these geospatial assets were consolidated into a new division named Hexagon Geospatial.

Between 2015 and 2017, Intergraph’s various business units underwent rebranding: Security, Government & Infrastructure was renamed Hexagon Safety & Infrastructure; Government Solutions became Hexagon US Federal; Process, Power & Marine transitioned to Hexagon PPM. In June 2022, Hexagon PPM adopted the new name Hexagon Asset Lifecycle Intelligence to better represent its broadened portfolio of solutions.
