There are rumors going around that IOTA has partnered with Bosch, and the partnership will be announced in the next few days.
I started looking into this and think its likely true because if you search 'Bosch IOT', they have a webpage describing their current Bosch IoT Suite which they say "provides a toolbox for IoT applications as well as the platform for specific industry solutions"
There is Bosch IOT artwork and the company has clearly identified IOT as an area of interest.
I suspect Bosch will be the first of many other partnerships to adopt the IOTA blockchain.
Here is the link for the current Bosch IOT page:
