Financial Services with millions of customers (and growing rapidly).

What we can get for that data is a major competitive advantage. We can offer much cheaper financial products since we model risk individually rather than as a cohort. It also allows us to have a single customer view despite reselling other companies products.

Building a single customer view with lots of disparate data sets is a big trend right now.

Ah, okay, so that makes sense. I've seen a few cases where data is just indiscriminately hoovered because reasons, and I can never help but wonder what the expected ROI on it is.
