Over the next two quarters, Box.net will also improve the dashboard users see when they look at the Box.net client, Levie said. The updated view will provide personalized updates, bringing to the top the most important documents for that individual. Ranking will be determined based on the content, activity and comments associated with each file.

Two enterprise customers who spoke with Levie onstage at the conference said Box.net and other cloud-based resources help their organizations work more efficiently and spend less time managing internal IT infrastructure. But there are challenges connected with moving to the cloud, they said.

"The technology change isn't nearly as hard as the people-change management aspect of it," said Steve Philpott, CIO of Amylin Pharmaceuticals, a maker of drugs for diabetes.

Craig Butler, CIO at a regional division of the American Automobile Association, said about 800 of his organization's 2,000 employees have worked at the AAA for 30 years or more and have to learn how to collaborate using a tool such as Box.net.

"It's not holding the information away, delivering it out just when I think it's right, it's actually working in a collaborative fashion," Butler said.
