Finding audience for my offline pixel event tracking tool

Hey everyone, I have a software product dedicated for tracking Facebook purchase/deposit events in any funnel where leads go dark after the landing page - pixel looses track (tracking via opt-in form, deduplicating -reporting events back over CAPI)
I am struggling with finding clients and right audience for pushing the product, I am waiting for my tool to be reviewed here (BHW marketplace) but it is taking forever to find anyone for the test.
I have been focusing on Igaming/Forex space only, but maybe someone can comment and open my eyes to a larger picture with places to advertise in and businesses to advertise for, this is a unique tool.
