This is a great question, and could simply be explained with how etiquette works in the music licensing industry.
"If the client is public, the money is private.

We state on our site which companies we work with. However, since these libraries' deal structures and payment amounts are stated publicly, we do not state the company name aside it.
That being said, after you land a placement - it's prettyyy easy to figure out where it went. 😉.
We just won't state it directly within the platform as a curtesy for a long relationship with these companies.
