San Francisco—Salesforce.com Inc. has launched a service that enables companies to build their own app stores. Dubbed Private AppExchange, it will enable users to easily distribute mobile, cloud, custom or third-party apps to employees. The new service, based on Salesforce.com's own AppExchange app marketplace, will allow company employees to install approved applications and request access to unapproved apps. The service allows CIOs “to give every employee instant access to the apps they need, across any device, to supercharge productivity,” Salesforce said in a statement. Private AppExchanges are expected to eliminate the need for employees to log tickets with IT departments and wait for access to their apps. Because Private AppExchange is intended to work with Salesforce's Identity service, which debuted last month, employees will be able to log in to multiple apps with one password, Salesforce said.
