Personalization Capabilities of ATG Commerce Bring Continuing

Education to Broader Audience

ATG (Art Technology Group, Inc., Nasdaq: ARTG), a leading developer of online CRM applications for commerce, portals, and relationship management, today announced that Fathom, a provider of online learning resources for professional development, lifelong learning, and students, has successfully launched the latest version of its Web initiative using ATG Commerce.

Fathom, a consortium of 14 leading educational and research institutions including Columbia University, the London School of Economics and Political Science, and the Woods Hole Oceanographic Institution, is capitalizing on the broad reach of the Internet to market and deliver online courses and seminars. In selecting ATG, Fathom executives recognized that the commerce site represents a core business channel and, in order to convince users to pursue multiple e-learning offerings, the site had to connect with the user on a highly personal level. In addition, with the extensibility and flexibility of ATG Commerce, Fathom was able to reuse code and build user profiles for personalization in a short period of time.

"What makes Fathom different from most online learning sites is our ability to offer a diverse selection of online courses and seminars that allow an individual to continue the learning process throughout their lifetime," said David Wolff, vice president, technology and production, Fathom. "In order to create and strengthen such levels of customer loyalty, however, you need to know your customer. The personalization functionality of ATG Commerce has enabled us to deploy a commerce site that allows us to understand and cater to the educational desires of our customers."

One of the primary drivers enabling Fathom to establish those customer relationships is the personalization functionality of ATG Commerce. With Scenario Personalization(TM), Fathom can create detailed user profiles from which it can direct targeted course information and promotions to the defined preferences of users. With out-of-the-box functionality like merchandising (discounts, coupons) and tracking site results, ATG Commerce enabled Fathom to target individuals based on their preferences and then obtain the information through ATG's tracking capability, to decide if the promotion was successful. By directing the most relevant information to individual users, Fathom can maximize the consortium assets at its disposal to the fullest extent.

"Individuals who turn to online learning are seeking a source of continuous growth, so it is only natural that you would want to connect with these individuals at the most personal level possible," said Victor Cheng, senior director of strategy and business development, ATG. "By deploying ATG Commerce, Fathom can continually provide the access to enriched learning experiences its customers are seeking."
