I have a US product that does about $1M/year with 200+ reviews. I’d rather not open my own CA/EU accounts. A business partner has mature CA, UK, and EU accounts. We’re thinking of doing this:

I license my brand to him

He lists under my ASINs (same product)

I also run the ads on his accounts (I already do that)

I already have 30% equity in his store

Two main questions:

What’s a fair revenue share for this arrangement? Should it be based on net sales or contribution margin? The partner’s store also sells other products, and I already get 30% of total store profit.

For Europe: I searched for similar products by keyword and found nothing. But when I search by ASIN, I see a competitor being sold by a different seller. Is this a red flag for IP infringement? Or does it just mean competitors haven’t entered Europe yet?

Would love to hear from anyone who’s done a similar cross‑account brand licensing deal.
