How do I best avoid being cut out of a double close deal?

So I got a response to one of my adds from a guy looking for an equity partner for a double close deal he has and after looking at the numbers the deal makes sense. But I don't have the money myself to close the deal but I do know a transactional funding company that could with whom I have developed a relationship with. How do I make sure that once I introduce them to each other that I don't get cut out of the deal. I am not so much concerned that the funding company will try to cut me out as the guy bringing the deal as he currently has the deal locked up under contract and my name is nowhere on the contract.
