Well, it's not my business. I am just an employee, so I'm a bit hesitant. 
It's a medium-sized (~250 employees) mechanical engineering company from Germany.
Our software is just one small part and quite specialized. It isn't sold as a stand-alone product, but always tailored to the machine/production line. So there is no technical information publicly available.
And our team is really, really small. I am mainly doing the platform development, while the colleagues are commissioning it.
I think we already had a discussion a while ago where I gave some details of our use-case of Node-RED on this thread: Increase canvas size? (supersize flows!)
