Maybe it's different in the states, because a lot of tech giants are based there. But in Europe, I feel like, there are banks that inherently have a lot of data and they can use BigData stack for ETL and other stuff, and there is the rest who just want to get some data on users and sell them some products they don't really want, it's not necessary an advisement company by itself, it can be an analytical platform or just a department in some big e-store.
