In finance, the enquiry is never exclusive
Somebody looking for a loan, a policy or an investment fills in three or four forms in one sitting, usually on a phone, usually in the evening. They are not comparing brands at that point; they are waiting to see who calls. The provider that reaches them first sets the terms of the comparison and, crucially, becomes the one they hand their documents to. Everything after that is a matter of not losing them.
So nurture in finance has an unusual shape. The front end is a speed problem, the middle is a paperwork problem, and the back end is a timing problem, because a large number of enquiries are simply too early or currently ineligible. Each part needs a different mechanism, and most teams run only the first one.
