I feel that 50/50 is the standard rate for JV promotions, but I believe that when someone is doing their first launch or working with someone for the first time this is not antiquate.
Until you have proven yourself and your product, list, service, software ext. you need to realize that the list owner is the gate keeper and should receive a higher percentage of the sale than the producer, because they are increasing their risk by working with you and need to be compensated for the higher level of risk. (high risk - high return)
This will show the JV partner that 1- you have faith in your product 2- you understand the position of the list owner 3- you intend to develop a long-term relationship, because you are not looking for a quick buck from their resources
It comes down to the fact that the list owner needs to understand what your intentions are and trust you.
A high commission is not the only way to do this, producers also need to go the extra mile to facilitate the deal and make a "Yes": as easy as possible. (provide marketing materials, samples, follow up follow up...).
