ATG Launches Catalyst Program to Drive Commerce Innovation

How the program works

Program content is hosted in a central repository on the company's
online customer and partner community (http://community.atg.com),
where ATG product and technology experts can add Catalyst Assets as they
are developed. These Assets will provide members with ideas, guidance
and reference code that enable new extensions to ATG products, and
integrations with partner technologies and emerging technologies, such
as mobile and social commerce tools. By presenting possible use-cases
related to emerging technologies, as well as instructions and code for
merchants to leverage, ATG will stimulate creativity and technological
advancement among its vast global network of customers and partners.

"In launching the ATG Catalyst Program, we wanted to establish a forum
for partners, customers, and internal teams to share ideas, innovations
and code," stated Ken Volpe, ATG's senior vice president of products and
technology. "The Catalyst Program provides ATG customers and partners
inspiration and guidance to leverage emerging technologies. This program
complements our overall product strategy and roadmap."

New Catalyst Assets will be continually added in the coming weeks and
months. Some of the first Assets ATG has already made available include
applications and demonstration code that assist merchants in launching
mobile storefronts and integrating popular social networking sites into
cross-channel commerce plans. In the first few weeks alone, these Assets
have been downloaded by more than 230 developers, who are using the
valuable resources to enhance various cross-channel
commerce initiatives.

ATG Mobile for the iPhone(R)

One of the first Assets to launch as part of the ATG Catalyst Program,
ATG Mobile for the iPhone is a native software application, built on the
latest version of the Apple SDK to provide a foundation for
sophisticated mobile storefronts optimized for Apple's iPhone(R)
and iPod touch(R). ATG Mobile for the iPhone provides a fast,
feature-rich and user-friendly framework that can be easily customized
for individual brands, clients or campaigns. The native application
features an intuitive interface with flexible screen layouts for
customer-specific styling, and embraces and leverages typical iPhone
features and user experience, so merchants can create mobile stores that
are compelling and appealing to iPhone and iPod Touch users.

The framework empowers merchandisers with the ability to easily change
the presentation of mobile promotional content, while also supporting
basic and advanced registration, and check-out processes that make it
easy for end-users to complete transactions. ATG Mobile for the iPhone
was developed using the same core commerce functions that ATG customers
use to power their Web stores, which means customers can seamlessly
transition across channels, and their shopping cart and registration
details will follow them wherever they go.

ATG Social Rewards

Additionally, ATG customers and partners are able to use the ATG Social
Rewards Asset to extend e-commerce sites powered by the ATG Commerce
platform to social networks like Twitter and Facebook. This module
enables users to share information about a product with their favorite
social networks and provides a means of rewarding the user for sharing
by awarding "Social Rewards Points" to the user's profile, which can
then be used for any personalization activity, including discount
promotions and benefits.

"ATG customers and partners are among the most innovative when it comes
to adopting emerging technologies that add to the customer experience
and ultimately drive revenue," said Nina McIntyre, ATG's senior vice
president of marketing and chief marketing officer. "Important new
mobile device applications and social commerce networks are delighting
customers and shopping habits are changing on a daily basis. Our
customers need to experiment in this space, engage their consumers and
prospects, and change their approach just as quickly as consumers change
their habits. The ATG Catalyst Program is an open-source-inspired
initiative that will help the brands who have put their trust in ATG
leverage expertise and creative ideas from our strong community of
developers and partners."

Assets for Extending Other Technologies and Investments

Instructions and code are available to help merchants maximize their
investments in other ATG products, as well. An example of this would be
adding the Catalog Connector Asset to Web stores, which simplifies the
process of integrating ATG Recommendations with existing product
catalogs. Another example involves utilizing the Interests Module Asset,
a code extension that enables the tracking of customer behavior on a
site (whether anonymous or authenticated) and stores that information so
it can be used for personalization purposes.

already available, ATG customers and partners can visit http://community.atg.com.
