Onyx(R) Software Corporation, a worldwide leader in customer management solutions for the enterprise, today announced that AIG Edison Life Insurance, a Tokyo-based division of American International Group, Inc., world leaders in insurance and financial services, has selected Onyx to support its ongoing Customer Relationship Management (CRM) strategy and business growth. AIG Edison Life is leveraging the Onyx Migration program, announced September 28, 2005, to replace a Siebel (Nasdaq:SEBL) implementation that had proven extremely costly to maintain.

“After considering our options, it was clear that AIG Edison had to re-address our CRM strategy. Our current CRM environment with our current vendor was requiring a lot of maintenance for every AIG Edison product change, and an upgrade to the latest supported web-based version was going to cost over one million dollars,” said Tohru Futami, chief information officer of AIG Edison Life. “Thus, AIG Edison wanted to be able to leverage work being done by other projects in AIG Japan since Onyx was chosen as the standard in June 2004,” continued Futami.

AIG Edison determined that an Onyx solution would provide the best integration with their current systems, a strong analytical tool set, and an architecture that would allow them to scale as they grow, at a cost effective price. “The Onyx solution will be seamlessly deployed into our existing architecture and require minimum resources to maintain. That’s a very important consideration to AIG Edison Life as our CRM software needs to enable us to scale up to support our growing business. Onyx stood clearly above its competitors for AIG Edison Life — it’s the ideal solution for our needs,” concluded Futami.

“Enterprise CRM customers like AIG Edison are naturally concerned with the future and ongoing costs of their existing CRM infrastructure in light of recent market events,” said Todd Chambers, chief marketing officer of Onyx Software. “AIG Edison understands that Onyx provides them with an enterprise solution that will support them as they continue to grow.”
