Hai Tani (TaniAI) is a WhatsApp-first agentic marketplace for Indonesian smallholder farmers. Its flagship is a
  stateful buyer↔farmer negotiation bot: a buyer chats what harvest they need ("butuh bawang 500 kg") and their budget;
  the bot automatically notifies matching ready-to-harvest farmers, collects their quotes, verifies buyer specifications  (size, cuts) with each farmer, allocates cheapest-first, locks the deal, then drives fulfilment end to end — shipping
  address (text or Share Location), seller photo verified by a vision judge plus final buyer verdict, ship schedule, and  two-party payment confirmation. No app to install: farmers just chat the Hai Tani WhatsApp number.

  Supporting tools inside the same agent: live vegetable/fruit market prices with anomaly alerts, a photo-diagnosis loop  and cited agronomy Q&A (framed with verified sources + PPL escalation), ERP farm logging, QR registration cards,
  Google Sheets sync, and a public/admin monitoring dashboard. Built on the WhatsApp Cloud API (Meta for Developers) and  Meta Model API — first in a multi-provider AI dispatcher — and developed with Muse Code (Meta).

  Revenue: tiered take rate (5/2/0%) on the negotiated spread, remainder returned to the farmer; subscriptions to Hai
  Tani; trade payments via licensed gateway under Hai Tani supervision.

  Problem Solved

  68% of Indonesian smallholders sell through the same middlemen: harvests are bought cheap at the farm gate while
  traders control market selling, leaving farmers razor-thin margins and zero direct buyer access. After talking to many  farmers, the founder (a 6-year ornamental-plant farmer) found buyer access — not information — is the #1 complaint.
  Hai Tani removes the gatekeeper by putting a tireless negotiator in every farmer's WhatsApp: verified demand reaches
  farmers instantly, bargaining is transparent and recorded, and every deal is supervised to completion — "Dari Petani,
  untuk Kesejahteraan Petani."
