  ## Work with eSapience
  
  In the mid-2000s, Evans and his wife, Karen L. Webster, were chairman and managing director respectively, of the now defunct eSapience public relations firm of Cambridge, Massachusetts. Karen Webster also is the founder of pymnts.com. An article on boston.com on March 10, 2007, quotes eSapience's website, which was live at the time, as describing itself as '"not merely a public relations firm, but a "new media and research entity that shapes the debate on issues that intersect law, economics, and policy" through "a global network of academics and other public intellectuals."' One of eSapience's clients was Maurice "Hank" Greenberg, former president of the American International Group (AIG), who was forced out as chairman and chief executive in 2005 by AIG's directors. The directors did this after then Attorney General Eliot Spitzer of New York brought charges of fraud and other violations against Greenberg. eSapience was hired by Greenberg to create a branding campaign for him.
  
  On March 10, 2007, the Boston Globe reported on the lawsuit that eSapience filed against Greenberg's company, New York investment firm C.V. Starr & Co., for allegedly refusing to pay $2 million in bills from the image campaign for which eSapience was hired. Several other publications covered the legal dispute, focusing on the ethical use of academics, such as Evans and Richard Schmalensee, dean of MIT's Sloan School of Management, in this rebranding campaign. On March 12, 2007, The New Republic reported on the lawsuit, with the subheadline: "How a shady, right-wing p.r. firmed tried to buy academic influence." Other media outlets, such as The Financial Times, the Daily Kos, HCRenewal Blog, Harper's Magazine on Washington, to name a few, covered the issue.
