Titanium Seal Software was the name of an early "rack vending" product line of shareware software titles in the 1990s. Its counterpart was Gold Medallion. These rack line companies were founded in 1992 by Bob Burns and Jim Perkins. Assisting in development was Randy MacLean, who with Perkins, had earlier founded FormGen.
Fairly prolific, they released shareware for dozens of titles, including the popular Wolfenstein 3D. At some point, the Gold Medallion name was dropped and Titanium Seal was acquired by SoftKey International.
