By Texas grocer HEB: intelligently builds customer-specific shopping lists from events, lifestyle, budget and brand preferences, aligned with store inventory.
Being built by an actual grocer is probably decisive. Most hackathon entries address an imagined user; this one is wired to real store inventory and slots into a routine customers already have. Details like budget ceilings and brand loyalty are not things you invent at a whiteboard — they come from knowing the aisle. It also happens to demonstrate precisely the kind of retrieval-grounded application Databricks wants to see running on its own platform.
