I think it's probably a financial engineering company over everything else, but I mean "tech company" insofar as this post is going to the top of HN in a way a post about Regus might not.
I agree but are you saying that if it was a tech company, it would be worth the 48 billion? Also, is it THAT much different from AirBnB that is considered a tech company? What 'tech' does AirBnB offer that qualify it is a tech company?
