We're making apps based on a book. We have approached the author and he has agreed to let us use the trademark and help us promote them in exchange for revenue share. The revenue comes from affiliate links, app sales and potentially other channels. He has now asked us for a rev share proposal. What are our rev share options to propose?
On a side-note, the author is influential and we highly respect him and value this opportunity. But still we'll need to cover the costs and grow the business.
We appreciate any pointers,
