Chordiant Mesh Attracts 20 Marquee Customers in First Year.

Innovative Development Community for Customers and Partners Attracts Global Brands, Validates Vision of Transparent Collaboration

CUPERTINO, Calif. -- Chordiant Software, Inc. (Nasdaq: CHRD), the leading provider of Customer Experience (Cx[TM]) software and services, today announced that Chordiant Mesh, its innovative development collaboration community, has grown to 20 marquee members since its inception just over one year ago. Membership includes some of the world's largest consumer brands in the healthcare, insurance, banking and telecommunications industries. Chordiant Mesh allows open and continuous collaboration among Chordiant customers and partners throughout the development and deployment of Chordiant applications and solutions.

Chordiant Mesh collaboration streamlines product development and ensures high value features by providing transparent participation in the development process for all members of the Chordiant ecosystem. Every day within Chordiant Mesh, users and domain experts from customers and partners work in tandem with Chordiant staff teams during each step of the product development lifecycle. Among many others, Chordiant Mesh collaboration now serves the following global brands: BSKyB, DAK, CompuCredit, Gothaer, HSBC, ING Poland, InfoGain, Ness Technologies, and Tata Consulting Services.

BSkyB, the UK's largest pay-television company, uses Chordiant Mesh because it makes developing and implementing high-value, mission-critical customer experience solutions significantly easier and less risky. Even the basics, like figuring out how the software works or how best to apply it to a business problem, becomes much easier when supported by a community that includes people who actually developed the software and solutions and partners that have implemented them. Because of the continual collaboration and planning transparency, Chordiant Mesh also ensures BSkyB that the software created using Mesh will provide the functionality required from the point of deployment.

"This is the most pragmatic approach to product development between a software vendor and its customers that we've ever seen," said Ray Gerber, chief architect, Valued Services Solutions for CompuCredit. "It's such a refreshing change from traditionally segregated and opaque development processes to work in the same circle as Chordiant staff engineers. There is truly no wall between our development team and theirs, everyone is treated as peers, and we get answers to questions and influence the product direction in real-time."

Chordiant Mesh radically transforms enterprise software and solution development, enabling member companies to benefit from the speed and innovation of community-based development environments within the security of a professional software organization. The Chordiant Mesh ecosystem also gives technology partners, professional services organizations, and independent software vendors direct access to underlying source code and a global community of experts with whom to collaborate. Solutions developed using Chordiant Mesh are built on the 6th generation Chordiant Enterprise Platform, a process-driven SOA and AJAX-based platform for building and deploying best-in-class customer experience solutions.

"Chordiant Mesh collaboration was founded on the principal that continuous conversation among stakeholders is a breakthrough metaphor for developing high-value software," said Jim St. Jean, vice president, Worldwide Engineering for Chordiant. "In Chordiant Mesh, the people who will be using the software to solve business problems shape its creation throughout the product development process. Traditional software development methods, where only 40-60% of the functionality desired by the customer actually becomes a reality, can't keep up with rapidly changing market landscapes or how savvy customers have become. Chordiant Mesh brings a dynamic new environment to the table, and our customers have immediately seized its value."
