KDDI and Salesforce.com Announce Strategic Partnership to Deliver On-Demand Mobile CRM Solution for the Japanese Market

KDDI and salesforce.com to launch free trial service in August to provide access to business critical customer data via KDDI mobile phones

Tokyo — June 13, 2005 — KDDI Corporation, Japan's leading fixed line and mobile phone service carrier and salesforce.com [NYSE: CRM], the market and technology leader in on-demand CRM, today announced a strategic partnership to deliver on-demand mobile CRM solutions for the Japanese market. Known as "salesforce.com Mobile Edition for au," the innovative joint offering will deliver comprehensive, wireless CRM functionality that enables users to benefit from their salesforce.com data anywhere, anytime using KDDI's mobile phones and wireless network.

Available to salesforce.com Professional Edition and Enterprise Edition subscribers in Japan, the solution enables users to download data from the salesforce.com service to KDDI phones; view, edit and input new data that can be synchronized with salesforce.com; and search data both offline and online. The service will be delivered in three phases: It will initially be offered in July, on a complimentary pilot basis to select customers. The pilot will be extended to all salesforce.com Professional Edition and Enterprise Edition customers between August 1 and September 30. The service is then expected to be generally available in October at a cost of JPY 1,575 incl. tax per month, per user.

As part of the partnership, salesforce.com will deliver mobile versions of its applications, in conjunction with KDDI-designed middleware, to run on BREW® (Binary Runtime Environment for Wireless), Qualcomm's industry-leading platform for mobile data applications. The middleware enables KDDI phones to communicate with the salesforce.com on-demand service via SOAP (Simple Object Access Protocol), a high-speed XML-based messaging protocol.

All application middleware was developed by Technoface Corporation, a Japanese joint venture between Hokkaido University and a number of local high-tech-oriented companies.

The joint wireless solution also includes comprehensive security measures designed to safeguard valuable customer data. For instance, if a customer's phone is lost or stolen, they can call salesforce.com Japan and request the deletion of any salesforce.com data residing on the phone without affecting data housed on the salesforce.com server itself.

"Salesforce.com is very pleased to work with KDDI to deliver its next-generation, on-demand CRM solutions to wireless customers across Japan," said Jim Steele, president of salesforce.com. "Whether they're in a train or a subway, in a taxi, or in a customer's lobby, salesforce.com customers in Japan will be able to have their critical sales data within easy reach. By leveraging the salesforce.com and KDDI solution, salesforce.com users don't ever have to worry about being out of the loop."
