Larry Ferguson became president of System Associates Inc. (SAI) in 1985 and led its rapid growth from $5M annual revenue to $50M. SAI created the SAINT hospital information system, initially running on obscure Point Four hardware. American Express later acquired SAI and renamed it FDC, using it to acquire other HIS vendors like McAuto and Gerber-Alley. HBOC eventually acquired FDC and several of its products, rebranding SAINT as Paragon. Though early Paragon adopters faced challenges, McKesson later saved the product which is now one of the most successful small hospital HIS platforms.
