Halligan also noted a number of other changes he expects to see in the near future when it comes to inbound marketing strategy, particularly in tools and methods of delivery.

"HubSpot's next major initiative is that we've felt the nature of n COVER STORY buying has changed a lot," said Halligan. "The way you need to sell has got to change. That's where we're headed, and I'm super excited about that."

As an example, Halligan pointed out HubSpot's latest platform to aid in the sales process: Signals.

Another change Halligan noted was how various generations live, think and buy differently. From Baby Boomers, to Generation X, to Generation Y and the Digital Natives, businesses have to create different strategies focused around different buying behaviors.

"I think everything's going to have to change to deal with those new generational realities, and there needs to be a new platform to deal with all of these realities," said Halligan. "That's what I'm excited about with HubSpot." Finally, Halligan predicted more changes for the world of social media, including a fair amount of convergence.

One bold prediction Halligan made was to expect Facebook to bolster its search capabilities in order to compete with Google and for Google likewise to become more social when going toe-to-toe with Facebook.

"All of them are going to compete more and more for our time."
