At one point, U.S. Concrete CEO Bill Sandbrook thought the economy was in the middle endings of its last cycle.
Now that President-elect Donald Trump will step into the White house, however, he's changing his tune.
"Now what we are planning on is an extension of that. So, maybe we had a 2 or 3 year runway. Now we are looking at 3, 4, 5, 6 years of improved economic opportunities," Sandbrook said.
U.S. Concrete is a major producer of concrete for commercial construction, residential construction and infrastructure building. The stock has rallied 30 percent since the election, as it is expected to be a large beneficiary to Trump's infrastructure agenda.
For years, Cramer has watched the evolution of cellphones transform from something that resembled a brick, to a blackberry and then to the iPhone. What he found interesting is that office phones haven't changed much.
DialPad is a private company that is working to transform the way businesses conduct communications. It has developed a cloud-based platform that lets its customers turn any device — smartphone, tablet, laptop —into a business phone. This includes voice, video, instant messaging and online meetings.
DialPad has picked up 25,000 paying customers, including Uber, Motorola and Netflix. Cramer spoke with co-founder and CEO Craig Walker, who explained how they went from working at Google to creating the company.
"We used to go and pitch this to Google apps customers, and we talked to them like 'hey wouldn't this be great if you had this for your business' and they all wanted it. So, that got us thinking 'hey if you're moving your business to the cloud for your email and everything else, your phone system should go with it.' So then we left to go do that," Walker said.
In the Lightning Round, Cramer gave his take on a few caller favorite stocks:
KKR & Co: "I'm a believer. I think it's good because we've got a market that wants to do some IPOs. We need new material."
OPKO Health: "In the end, I've been sticking with it from the low-single digits to the mid, and then it went the high teens and came back after that acquisition, but I still like it. Phil Frost [CEO] is a money maker and I still believe it. I believe in their tests, too. I think they're very good."
