Whitelisted creative typically buys a 10–25% CTR lift and a modest CPM discount from higher relevance scores. It is not a different business model, it is a compounding edge.
Structure it as a flat usage fee per 60 days plus a performance tier, not as perpetual rights. Perpetual asks inflate the quote and you rarely run creative that long anyway.
Insist on partnership-ad access rather than login sharing. Account access disputes end relationships and lose you the creative library.
