Partners are a critical part of the growth of a smart home ecosystem.

Smart devices from these companies also work with Alexa, which is understandable given Amazon’s two-year head start on Google in the smart speaker space. And Alexa boasts far more voice-based apps, with a library of 15,000 of what Amazon dubbed “skills,” versus 378 for Google Assistant.
