About
Abbie Wharff Rosenblum
A beautiful brand deck and a credible commercial case are two different documents. Most founders
only ever build the first one.
I wasn't the buyer. I sat beside them with a different lens. When a merchant said
"I love this brand," my job was often to answer the question underneath it: does the business
support that decision? That's the combination I've come to trust in myself — product instinct and
curiosity, trained to be pressure-tested against the economics.
ShelfLine is where I work that out in public. What I notice in stores, what the numbers underneath a
launch actually say, and where the two disagree.
