The Internet of Things (IoT) has attracted a lot of hype over the past few years, but which companies actually lead in building out their presence in the segment? According to new data from IoT Analytics, an analyst firm dedicated to the Internet of Things, IBM leads the pack, having pledged to invest $3 billion over the next four years in a separate division dedicated to connected devices. Google came in second, thanks in large part to Project Brillo, a development platform for the Internet of Things. Coming in third on the list is Intel, which has made significant investments in embedded systems and connected devices, but hasn’t made as many big IoT-related moves in the past quarter as IBM and Google. In fourth is Microsoft, which plans on making its upcoming Windows 10 into an IoT-ready platform. Just behind it, in fifth place, is Cisco, which recently rolled out 15 IoT products related to cybersecurity and other areas. Check out the latest IoT-related jobs. IoT Analytics bases its rankings on social-networking and traditional media mentions of a particular company’s work on IoT, number of company employees that use the “Internet of Things” tag on LinkedIn (which can give an idea of whether a company is hiring more IoT workers), and how often companies surface in Google searches in conjunction with IoT. That methodology puts a lot of emphasis on press hype over, say, research and development metrics, or device sales. There are obviously other ways to tabulate a company’s prominence within the IoT industry—and all the companies mentioned on IoT Analytics’ list could probably make good arguments for why they should be first in place of IBM. Nonetheless, the takeaway from the list is that some of the most prominent companies in tech aren’t treating connected devices as a sideshow—there’s clearly some heavy investment in IoT. Which means, for tech pros, opportunities to land jobs in a field that will only grow in coming years.
