Since becoming KPMG U.S.’s first female CEO in July of last year, Doughtie has presided over a major growth period for the professional services company. The Big Four firm posted a 14.8% revenue increase for its 2015 fiscal year, to $7.9 billion, making it the fastest growing of its U.S. peers. But the focus is on innovation as well as numbers: This year the company expanded its partnership with Microsoft and announced an agreement with IBM to apply its Watson technology to KPMG’s services. Doughtie also unveiled the firm’s first high-tech workspaces, called Ignition Centers, that more closely resemble the offices of a hot young startup than a professional services firm. A 30-year veteran of KPMG’s audit and advisory businesses, Doughtie runs the KPMG Women’s Leadership Summit, which brings together the top women in business, politics, and sports.
