👉 The brothers, Tom and David Shaw, co-founded CyberSource, a pioneering computer science consulting firm, in 1985. Their innovative approach to technology consulting and software development led them to develop their own personal computing systems, notably the Shaw System, which was one of the first integrated computer systems designed for business use. This venture culminated in the creation of Shaw Software, where they developed and sold software applications, including the influential Shaw Operating System (SOS) and later, the popular Lotus 1-2-3 spreadsheet program. Their work emphasized practical, user-friendly software solutions tailored to business needs, significantly influencing the personal computing landscape of the 1980s and 1990s.
