Enterprise software has been one of the hottest areas in tech in recent years. If you believe Santi Subotovsky, it's not going to cool down anytime soon. Subotovsky, a general partner with Emergence Capital, thinks the enterprise sector is going to continue to boom, driven by some big trends, such as the near-ubiquity of smartphones and the increasing sophistication of artificial intelligence technologies. Those trends could make older providers of enterprise software, including Salesforce, vulnerable -- and should open up opportunities for upstarts, he said. "We're looking at next seven to 10 years," Subotovsky told Business Insider in a recent interview. "We see some major transformations in the way people are using technology at work."
