Mother-in-law's at Rainbow Grocery Cooperative
Rainbow Grocery Cooperative is a member-owned co-op running 1 Bay Area store, large-format at about 36,996 sq ft each, indexing high on clean-organic versus other Bay Area grocers.
It’s already on the shelf here, with 4 SKUs across 3 categories. The growth is depth and breadth: 1 category to widen and 1 new door to enter.
Lead with House Reserve Kimchi, Whole Napa Cabbage in Kimchi.
Rainbow Grocery Cooperative stocks kimchi thinly, so a differentiated snack stands out instead of becoming the Nth option on a crowded shelf. It already earns space at 4 other Bay Area grocers.
Rainbow Grocery Cooperative carries kimchi in real depth, 15 SKUs against a fleet median of 5, so a new entry there is the Nth option, and its per-unit price would likely sit near the top of a crowded shelf.
