Agreed. They might get dibs on an early “quota” of the production but I doubt SHMP would grant them exclusivity in the supermarket space.
I think Amazon/WF could be an early customer but longer term fits best as a licensee. They could license, then produce as much as they could sell. Amazon would do their own distribution - they are world class in that regard.
I also would not rule out Costco as a licensee. The alignment on values is not as strong as with WF, but they are great at selling mass quantities and have a history of doing their own production under the Kirkland brand (when they know they can produce a quality product cheaply and consistently). I could see Kirkland “organic” shrimp.
