Quarterspot put them from and center on the contracts for everyone to gawk at.
There have been several deals that I did non-MCA that I was not getting paid from the lender at all, or the lender pay was extremely low, and I gave them a fee agreement UP-FRONT in order to let them know that if I succeed, I make 2%, and it's not necessarily any of their business if the lender/funder also pays me.
I just had a client ask me since he knew that the funder paid me, and I politely refused and he said, "I'll just ask them," and, of course, they probably won't reveal it.
Not that he cares, it just feels like an invasion of privacy.
