Austin, Texas--Three marketing executives who helped expand Dell Computer Corp. into a multibillion-dollar corporation have joined forces to launch a new marketing company. The company, called nFusion Group, combines the resources of e-business developer 1215 Media with The Ellett Group, a sales and marketing firm. NFusion will focus on creating Web sites, direct marketing and advertising. At the helm are managing partners Thomas Martin, Jay Watson and John Ellett, who is also the CEO and will manage the company's day-to-day operations. During their tenure at Dell, the three played key roles in taking the company from a $59 million a year in revenues to $27 billion in annual revenues.
