From its founding in 2006, Privilege Underwriters Reciprocal Exchange (PURE) set out to create a customer-obsessed business model that was differentiated from competitors. The result is a company that has grown 40% or more each year and has one of the highest Net Promoter Scores (NPS)℠ in any industry. This case study offers lessons to other companies about how they can create a customer-obsessed business model or evolve their culture to counter threats from customer-obsessed challengers.
