Marc Benioff has announced Salesforce.com is preparing to launch a rival to file sharing service Box, called Chatterbox.

Speaking at TechCrunch Disrupt with TechCrunch founder Michael Arrington, Benioff explained that the application will be built on the Salesforce Cloud platform and be a “Dropbox for the enterprise”.

He said: “[Our customers] want it integrated with our platform. They want our trust model, our security model. They want to have application services. They want to build apps with Force.com and do Chatterbox. They want to use Heroku and do Chatterbox. They want to use it on their own. So we have to step up and deliver Chatterbox.”

The Salesforce.com founder also announced another new arrival, Salesforce Identity, which will allow users to sign into multiple apps using a single log-in, and see the company compete against Cloud management start-up Okta.

But Benioff added that as a founder of Box, he's not looking to kill start-ups.

“We’ve invested in a couple of them, we compete with a couple of them, we partner with a couple of them, and that’s kind of the nature of the industry,” he said. “Our industry is not about the Hunger Games. I don’t look at our industry as a zero sum game,” he said. 

Full details of both Chatterbox and Identity are expected to be announced at Salesforce.com’s Dreamforce conference next week.
