CB Insights, an analyst firm specialised in tracking technology companies, investors and acquisitions has pulled together a rather novel way of representing the IoT ecosystem. It presents companies, VCs, private equity firms and acquirers in a conveniently colour-coded “Periodic Table of IoT”. As in the periodic table from our days in chemistry class, the characteristics of the ‘elements’ vary as we traverse the table, in this case from the technology firms in individual verticals such as wearables, connected home and healthcare before moving on to the various category of investors. Whilst not comprehensive, it is nevertheless a useful guide to some of the main players.
