November 05, 2009. Cary, North Carolina.. SAS, the largest private software company, makes a product called business intelligence or business optimization software, that looks for usable nuggets of information and insights in vast quantities of data. As the market for these types of products grows, SAS faces competition from some of the giants in the industry, such as Microsoft and IBM. The company differs from most in that it also provides many services for its employees, such as primary care doctors, daycare and a gym. . SAS has built a large solar farm on the property that they use to sell electricity back to their utility provider. Recent coyote attacks on sheep have made them raise the fence, which was being installed by Ryan Smith.
