Related to this, I seem to remember that there were talks about some start-ups doing this kind of stuff on millions of people’s profiles, this was before Cambridge Analytica, I wonder what happened to them. A former colleague of mine (very smart guy) ended up working for one those start-ups back in the day (2013-2014), that’s how I first learned about their existence and about their business model.
Many of them were acquired by larger commercial entities that service the defense/intelligence community. It's also possible to license and process much of this commercial data from brokers.
