Concept Paper · Retail & Commerce

Fast, low-cost, reliable — for every neighborhood.

A hyperlocal retail operating system connecting neighborhood retailers, suppliers, and shoppers through voice- and photo-led AI ordering, with a flat monthly fee instead of a commission cut. This paper separates the real, live ordering core from the payments and monetization layer still ahead.

Neighborhood retail runs on commission-based delivery platforms that take 15–25% of every order, or on no digital layer at all. Suppliers and small retailers need a fulfillment and ordering system that doesn't erode already-thin margins, and shoppers in dense neighborhoods need ordering that doesn't require typing a structured product search on a small screen.

Groser is a flat $2.9/month hyperlocal retail operating system rather than a commission marketplace: buyers order by voice, photo, or text; suppliers bid and fulfill from a unified order book; and retailers get a dashboard built for local network effects rather than platform lock-in. The bet is that hyperlocal density creates a defensible local monopoly a global commission platform can't easily undercut.

A real Supabase + PostGIS backend with live Gemini-powered ordering is running:

  • Multimodal ordering — a buyer can speak, type, or photograph a shopping list, and Gemini extracts a structured order from it.
  • Supplier bidding — a unified order book where suppliers price and accept orders through a real-time bidding flow.
  • Admin coverage intelligence — a live coverage map computed from a PostGIS nearest-supplier function, plus KYC approval and forensic order logs.
  • Built-in safety rules — prohibited-item blocking, a hard lock on prescription-only items, and a language-normalization gate, enforced as named rules in the ordering pipeline rather than left to manual review.
  • A rider dashboard for manual job acceptance and an Android distribution path via a Trusted Web Activity shell.

Planned next, ordered by what the flat-fee model depends on most:

  • Wallet & Payments — an in-app settlement layer; today, settlement happens off-platform.
  • A branded ad platform for CPG suppliers — today, only self-serve supplier promotions exist.
  • Live GPS rider tracking with ETA — today, navigation is a static map link.
  • Push notification delivery — the client and database trigger exist; the sending service is not yet deployed.
  • A connected marketing-site contact/pre-registration flow and a live AI chat widget on the marketing site — both currently static.
  • Neighborhood retailers wanting a digital order book without a commission cut.
  • FMCG suppliers and CPG brands wanting local distribution and, eventually, in-app advertising.
  • Local consumers who want to order by voice or photo instead of a structured app search.

React + Vite client, Supabase (Postgres, PostGIS, Auth, Realtime, Storage, Edge Functions), Gemini for multimodal order extraction, Cloud Run + Bubblewrap for Android distribution. Stage: GTM Ready — the ordering, bidding, and admin core are real and running; settlement, advertising, and live tracking are the near-term build.
