we measure every San Franciscogrocery aisle — which brands own the shelf, how they're positioned, and where the whitespace is. measured, not paid. (price is just one lens.)
a pilot canonical taxonomy — the beverage shelf grouped the way a shopper thinks, not by how each retailer files it. agua fresca sits with sparkling water, wellness tonics form their own aisle, and the same product lands in one place across every store.
every grocery category in the city — open one to see who owns the shelf, how it's positioned & where the whitespace is.
