Why Cloud Storage Provider Box Had a Killer QuarterShares rose 12.9 percent to $14.07 in extended trading on Wednesday.

Cloud storage provider Box Inc. reported higher-than-expected quarterly revenue as add-on services helped it win more customers to its content-sharing platform.

The company also forecast better-than-expected current quarter revenue and shares rose 12.9 percent to $14.07 in extended trading on Wednesday.

The company recorded increased traction for its additional data management services such as KeySafe and Governance.

The company, which won customers such as Unilever Plc. and Home Depot Inc., said its paying customer base rose to 57,000 at the end of fourth quarter, up from 54,000 at the end of the third quarter.

"It (services) allows us to work with much bigger enterprises and close much bigger deals with them as well," Box Chief Executive Officer Aaron Levie said, adding that the services increased average selling price for deals by about 20 percent to 30 percent.

While KeySafe allows a customer to take full control of encryption keys for its content, Governance allows businesses with sensitive data, such as financial services and healthcare companies, to comply with regulatory policies on sharing sensitive information.
