Tio Cumbana

Tio Cumbana is a digital agronomist for smallholder farmers — 500 million globally, 3.2 million households in Mozambique alone, feeding 2.5 billion people but invisible to agronomy. Most AI waits to be asked. Tio Cumbana doesn't. A long-running Claude Managed Agent watches each parcel, cross-references the farmer's photos, weather (via an MCP server), phenological stage, and Zimpeto market prices, and decides autonomously when to interrupt — sending a voice note in Portuguese with Changana code-switching. Two farmers asking the same question receive different answers because they are two different people with two different parcels and two different histories. I am the user. I run a 54-row farm in Maluana with my mother. The nearest agronomist is 40 km away. Today I came back to find a pest destroying our crop. This is the use case. The same Memory layer also gives supermarkets a live harvest-pipeline view, lowering waste and enabling pre-purchase contracts. One agent, every node of the value chain — only viable now, on Opus 4.7 + Managed Agents, at cents per farmer per day.
