One of the most ambitious attempts to pull together the key players in the IoT space can be found in TechCrunch, courtesy of Matt Turck of FirstMark Capital. Originally compiled in 2013, their ecosystem is divided into verticals, enablers and building blocks. Like any attempt to make sense of such a complex web of players, it is imperfect – see ARM, Amazon and Sony grouped rather randomly into a ‘Corporates’ bucket. What is startling is that this version has increased the number of companies from 199 to 612, largely driven by start-up activity. In a later post, I will attempt to propose a simpler model, but for the moment consider this an excellent ‘phone book’.
