Sigma Ratings CEO and leadership

Stuart is the Co-Founder and Chief Executive Officer of Sigma Ratings ("Sigma"), an award-winning MIT-incubated non-credit rating agency. Sigma uses deep domain expertise and cutting edge computer science to approximate and monitor financial crime-related risk at the company level. Prior to Sigma, Stuart was a Sloan Fellow at MIT's Sloan School of Management and a Term-Member of the Council on Foreign Relations. Before moving to Cambridge, he served as the Executive Director of EY’s Middle East practice focusing on strategic client engagement in key growth markets. He also served as the U.S. Treasury Department’s Financial Attaché to the Gulf Cooperative Countries (GCC), leading the Department’s regional efforts to ensure macroeconomic and financial stability and to combat illicit finance, including implementation of domestic and international sanctions programs. The role required regular meetings with Finance Minister/Central Bank Governor and Chairman/CEO level contacts across the region and constant interaction with senior Treasury leadership where Stuart advised officials on key regional policy matters. During his time with U.S. Treasury, Stuart also served as the Financial Attaché to Afghanistan for two years, overseeing the Department's largest overseas technical personnel investment. Before taking up post overseas, Stuart worked as a senior advisor in Washington, D.C. in the Office of Terrorist Financing and Financial Crimes and was detailed for 15 months to help stand up the National Counterterrorism Center’s Directorate of Strategic Operational Planning (DSOP) where he was named a “plank owner” of the directorate. For his work at home and abroad, Stuart received the U.S. Treasury Department Meritorious Service Award and two U.S. Treasury Secretary's Honor Awards.
