Strategy& is the strategy consulting business unit of PricewaterhouseCoopers (PwC), one of the Big Four professional service firms. Founded by Edwin G. Booz as Business Research Service in Chicago in 1914, the firm underwent numerous name changes before settling on Booz Allen Hamilton in 1943. In 2008, it split from Booz Allen Hamilton as Booz & Company, and in 2013 it was acquired by PwC, the largest consulting acquisition of the company’s history. The contract required PwC to drop the Booz name, and the unit became known as Strategy& in 2014. At the time of acquisition, the company had more than 80 offices in 41 countries.
