Internationally acclaimed designer to launch 5 sites in fall 2007 with ATG Commerce OnDemand to create sophisticated e-shopping experiences for women worldwide

CAMBRIDGE, Mass.--May 8, 2007--ATG (Art Technology Group, Inc., NASDAQ: ARTG), the leading e-commerce platform provider, today announced that fashion mogul Diane von Furstenberg (www.DVF.com) has selected ATG Commerce OnDemand to power the creation of five international Web storefronts which will launch in fall 2007. ATG was chosen to drive the re-launch of DVF`s global e-commerce efforts as a result of the company`s impressive client roster including its e-commerce success with Neiman Marcus, one of a very select few of elite retailers which offer DVF`s line of high-end women`s apparel. With ATG Commerce OnDemand, DVF will support and drive further growth in its e-commerce business through the use of advanced personalization and intelligent merchandising campaigns. Following the launch, DVF shoppers will enjoy a more sophisticated online experience complete with more relevant promotions, easier site navigation and fully customized Web stores fit for each of DVF`s five primary global markets--United States, United Kingdom, European Union, Hong Kong and Japan.

To drive sales growth and the increasing demands of international distributors and licensees, DVF determined that implementing ATG Commerce in a hosted environment will enable the company`s business users to exercise complete control in maintaining the site and presenting personalized marketing campaigns to consumers. DVF also cited ATG`s position of powering more of the top 300 internet retailers than any other e-commerce vendor as part of its decision to enter in a contract with the company.

"With rapid growth in the international markets, we needed a Web site that crystallized our brand equity and expressed Diane`s personality and lifestyle, while solving the needs of our international markets," said Paula Sutter, president, Diane Von Furstenberg. "ATG Commerce OnDemand will allow us to extend that presence internationally by creating five distinct sites that cater to our customers in every way possible, while permitting our merchandisers to create online programs and promotions in ways that will create the greatest impact within their local markets. We look forward to leveraging ATG products to take DVF.com to the next level"

"ATG`s Commerce OnDemand suite empowers retailers with the e-commerce features required to take their business to the next level without forcing business users to pay attention to the technical e-commerce hosting systems behind their sites," said Cliff Conneighton, senior vice president of marketing, ATG. "Receiving all the benefits of ATG Commerce in an on-demand delivery model was particularly attractive to DVF because the company wanted to focus less on software and more on tools they can use to directly manage their online catalog, search results, cross-sells and offers for individual customers as well as members of global market segments."
