Why it works

A E-commerce product in this shape is already a proven earner — real businesses here run at roughly $250K–1M/mo. See the live example for exactly how it's packaged and sold.

Who it's for

Solo developer or 2-person team with basic web skills; sells to grocers seeking foot traffic via API partnerships, and to shoppers via mobile-first web app.

How to build it

1. Pick one Nigerian metro (Lagos, Abuja, or Kano) and manually scrape or API-ingest prices from 3–5 major chains (Shoprite, Jumia Fresh, Lara Stores, etc.) weekly; store in Postgres. 2. Build a mobile web app (React/Next.js) where users enter their shopping list, then see which store/combo is cheapest and how much they save. 3. Add a simple affiliate or referral link layer: when a user clicks 'buy at Shoprite', you earn a small commission (0.5–2%) via existing affiliate programs or direct negotiation. 4. Launch in one metro for free to hit 1K weekly active users; partner with one grocer to subsidize cost or get data access in exchange for sending them comparison traffic. 5. Monetize via grocer subscription tiers (pay to appear higher in results, analytics dashboard showing how many shoppers priced-checked them) and affiliate commissions on successful purchases.

Your edge as a builder from anywhere

Nigerian grocers have fragmented, opaque pricing; no shopper tool exists yet to compare across chains in real time. You can win by moving fast in one metro, negotiating direct data partnerships with local chains (faster than international APIs), and accepting Naira + offline payment from grocers. The arbitrage is real: shoppers save 10–20% by switching stores, grocers gain incremental traffic—both
