Benioff also sent a message to Michael Dell, CEO of Dell, saying that he looked forward to seeing him and hearing him talk at Dell World. "OK, please don't cancel me like #oow11."

Speaking this week in San Francisco, Benioff took the opportunity to take another dig at Oracle's cloud offerings and said that the industry should be looking to start-ups for innovation.

"I have always thought that competition is very healthy. We need more of it, we don't need less," he said.

"You can see how [Oracle] continue to resist even multi-tenancy and shared systems, they are kind of moving towards it, but they are kind of not. I think they've really done a disservice to themselves."

He added: "But I think it's the start-ups that have been so exciting. We know that the young companies, a number of which have now been acquired, who have copied our model. We pioneered it, but we want to see the whole industry move to this new technology model."
