How do you ship an AI product now, when people don't even know they have the problem? (I will not promote)

Something I keep thinking about. Our AI does a job a specialist usually does by hand: it reads paperwork a company already filed (import taxes, in our case) and finds money they paid by mistake. It works on real files. Our problem is delivery. The people who get the money back don't have the files, someone else in the chain keeps them, and most don't know there is money to find. And reaching them is a second problem. Cold calls gave us 1 meeting out of about 65, maybe our volume is just too small, I don't know. Organic doesn't work either, because nobody googles "import tax refund" when they don't know it exists. So I see three ways to ship it: an app they use themselves, done-for-you where we run it and take a % of what we find, or through partners who already have the files and the trust. What would you try first in our case?
