Inspiration We live in a city where the same shopping list can cost you wildly different amounts depending on which door you walk through — and there's no way to know which door that is. New York is a hard place to buy groceries cheaply. There isn't a single Walmart in the five boroughs, so the discount chains that undercut regular supermarkets by 15–25% everywhere else simply aren't an option here. Grocery prices in New York run about 18% above the national average, and food costs in the metro area rose 56% over the last decade — faster than incomes. One in five New Yorkers, roughly 1.6 million people, is now food insecure. The number that convinced us to build this: reporters tracked the same eleven-item basket at twenty stores across the city for six months and found one store's basket running about a third higher than another's. Same items, same week. Nobody can shop around a gap like that on intuition alone — the price information just isn't published anywhere you can compare it. So we built the comparison layer ourselves.
What it does GroHop turns a grocery list into a route. Build your list. Search for products and add them, like any grocery app. Send it to your cheapest store. GroHop knows what your items cost at stores near you and does the comparison automatically. Plan the hop. If a second stop is worth it, GroHop maps the route between stores and shows you exactly how much you saved by hopping instead of buying everything in one place. Find a price fast. Scan a bar code, or point your camera at the product for an AI-powered image search — useful when there's no bar code, or the label isn't in English. Add prices yourself. Anyone can submit what they actually paid. Submissions are flagged as community data until a store confirms them. Seller mode. Store owners create a store, add their own products and prices, and pause the listing whenever they need to. Price verification. Stores review community submissions and confirm or correct them — the trust layer that keeps the map accurate as prices move. Pro mode analytics. Businesses see where they're priced against the neighborhood and where demand is going unmet, so they can optimize inventory.
What's next for GroHop Seed the map borough by borough. Price data has a density threshold before it's useful. We'd rather be genuinely accurate in one neighborhood than thin across all five boroughs. SNAP and EBT awareness — filtering to stores that accept benefits, and surfacing which items are eligible. Price history and alerts — tell someone when the staple they buy weekly drops, instead of waiting for them to search. Transit-aware routing. Most New Yorkers hop by subway and on foot, not by car; the route should account for that, and for what you're willing to carry. Deeper seller analytics, including anonymized demand signals for the small independent grocers who have no data team at all.
