The Yankee Group, a technology research firm, has been scooped up by private equity group Alta Communications and Emily Green, a former employee of Cambridge Energy Research and rival tech research firm Forrester. Green was named Yankee Group CEO. This is Yankee's fourth owner in a decade, after being owned by Decision Matrix for the previous 18 months, and Reuters Group before that. The technology consulting business is a tough one, because these firms often give much of their research and analyst insight away to the press. Following the dot-bomb implosion, many of these consultancies no longer have customers willing to pay premiums for their white papers. The Boston-based Yankee Group is profitable and has 164 employees.
