Sell harvested perishables in hours before they spoil
Tanzanian agribusiness entrepreneurs produce perishable goods before securing buyers, leading to unsold inventory, spoilage and lost capital.
HarvNow is a hyper-local, time-sensitive marketplace for produce that has already been harvested. Farmers post listings with photos, location and spoilage timer. Nearby buyers (hotels, markets, exporters) receive geofenced push alerts. Dynamic pricing automatically decreases as the timer runs out, creating urgency and fast transactions.
