Business/Technology Editors

CAMBRIDGE, Mass.--(BUSINESS WIRE)--April 11, 2002

Senior Executives Shift to Further Strengthen Technology, Product

Lines; Focus Squarely on Customer Satisfaction and Long-Term Vision

ATG (Art Technology Group, Inc., Nasdaq: ARTG), the leading developer of online CRM applications for commerce, portals, and relationship management, today announced that the company has enhanced its management structure to increase overall customer satisfaction and support the increased demand for its products' functionality. In a series of moves designed to address the rapid growth in the online CRM market, ATG has aligned and promoted key technology executives along its commerce, portals and relationship management offerings. The changes are in part a response to the departure at the end of April of ATG's Senior Vice President of Software Development, Bill Wittenberg, providing an opportunity to expand the roles of the company's online CRM industry pioneers.

As Vice President of Technology, Fumi Matsumoto will continue to bring his vision of how the Internet can transform the way business is conducted and apply it to ATG's family of online CRM applications. His more than nine years of experience working alongside ATG's co-chairman and CTO, Joe Chung, and Chief Strategy Officer, Jeet Singh, will continue to provide the solid foundation for the future of ATG's online CRM initiatives. Matsumoto will continue his vital role in ATG's growth, with additional responsibilities for long-range product planning and strategy. As one of the founding members of ATG, Matsumoto was a key contributor to the company's early transition from a services organization to one of the world's leading developers of online CRM applications.

"ATG's commitment to its customers and shareholders is the ultimate and ongoing goal for the entire management team," said Paul Shorthose, CEO, president and director, ATG. "As the leading developer of online CRM applications, it's incumbent upon us to maximize the company's value by having deeply experienced people responsible for ATG's key technical and product differentiators. The moves we're announcing today give our seasoned technology management team ultimate responsibility for the company's product vision and direction, and will maximize ATG's competitive position going forward."

To ensure that ATG's products, philosophy, technology and vision carry across all of the company's operations, Ken Volpe has assumed the role of Vice President of Product Planning and Strategy. Volpe will be responsible for driving the overall direction of ATG's product lines and for delivering ATG's customers with solid integrated solutions that meet their business needs. Volpe has been with ATG for four years and has been a significant contributor as ATG continues to focus on delivering online CRM applications to its customers.

Working closely with Volpe and Matsumoto will be six-year ATG veteran Ina Sipser, who has risen to the position of Vice President of Product Development. In this role, Sipser will oversee all company product releases, lead project management, product development, design and operations (including QA, performance and release engineering) and will head up globalization groups. During her tenure, Sipser made her mark starting as director of operations and was responsible for delivering nine versions of the product to market.

The promotion of Jeff Vroom to the position of Chief Architect rounds out ATG's senior technology management moves. Vroom's six years of experience at ATG provides the background needed for driving all project specifications, architectural design and technology selection. Among Vroom's key contributions to the ATG product lines will be his guidance and expertise in the consistent delivery of the quality core enterprise technologies behind ATG's online CRM offerings, and his work in the overall product design process. Vroom previously served as ATG's senior software architect for the Dynamo Application Server, known for its high performance and scalability, as well as the industry-first Data Anywhere Architecture.
