A top insider told Cramer this interesting tidbit about the GE chief.
"Jeff Immelt is running GE off his phone."
That's according to the always gregarious Marc Benioff, the chairman and CEO of Salesforce.com.
"We're working very closely with GE," Benioff revealed.
Speaking to Jim Cramer at his company's annual Dreamforce conference in California, Benioff explained that Immelt was using a new product called Salesforce1.
Essentially, it's a new service that allows any or all of Salesforce's 2,000 business applications to work on any device, including desktops, smartphones and tablets, he said.
"Jeff is an avid user," Benioff insisted. "Jeff says it's the number one piece of software he uses to run GE."
"It's the epitome of mobile," Cramer said. And if anyone is mobile, it's Jeff Immelt.
