More than 100m devices with Amazon Alexa have been sold

"More than 100 million devices with Alexa on board have been sold. That’s the all-too-rare actual number that Amazon’s SVP of devices and services, Dave Limp, revealed to me earlier this week. That’s not to say Amazon has finally decided to be completely transparent about device sales, however. While the company claims it outstripped its most optimistic expectations for the Echo Dot during the holiday season, Limp wouldn’t give a number for that. Instead, Limp says, Amazon is sold out of Dots through January, despite "pushing pallets of Echo Dots onto 747s and getting them from Hong Kong to here as quickly as we possibly could.""

Note - I'd assume that at least 95% of these would be Echo devices

Also - Amazon has over 10,000 employees working on either Echo or Alexa

Also - There are now over 55,000 'skills' (apps), up 120% year on year
