You can use the record feature in Wistia, and use Wistia for Chrome to make it an easy upload situation. Then you can see who watched your training videos, how much of them they watched, where they re-watched, etc, and use that knowledge to make better training videos in the future :)

They have a developer program and have been supporting 360 video for some time now.
I'm a big fan of Wistia. Not sure about pricing when it comes to 360 videos hosting but I know that they do host 360 videos and I'm sure they're doing it amazing. I'd recommend reaching to them and ask. https://wistia.com/product/360-v...
