Grant Lungren founded Grantlun Corporation in 1989 after serving for nearly a decade as President of Tanner Construction, which Lungren and his team built into the nation’s then-largest federal highway bridge contractor.

Grantlun’s first mission was to provide infrastructure contractors with a fully integrated estimating and project management system. That mission was accomplished in 1999 when investors provided capital to broaden Grantlun’s market and changed the firm’s name to Hard Dollar.

In 2002, after building the road map for Hard Dollar’s next-generation system, Lungren retired from his positions as Chairman and CEO of Hard Dollar and re-launched Grantlun in a different direction, this time with a mission to provide executive management consulting services to infrastructure contractors across North America.

Grantlun’s headquarters are in Bozeman, Montana, where its hard-working staff enjoy Montana’s great outdoors.

Established in 2015 as a subsidiary of Grantlun Corporation, Ironworks LLC is the synthesis of decades of construction industry expertise with cutting-edge AI technology. Founded by Grant Lungren and Adam Day, Ironworks owns the intellectual property associated with Grantlun’s equipment management-related consulting services.

Its mission is to produce an AI-powered Equipment Manager. To date, the initial design of all seven modules is complete and development of the Cost Estimator, Machine Catalog, and Data Miner modules is complete.
