The Problem
Why ShambaLine?
Farmers across East Africa have no access to expert guidance when their crops fail, their livestock fall ill, or when they need to plan around weather patterns. They have phones — 98% own at least a basic feature phone — but no internet, no smartphones, and often no literacy. Existing advisory services rely on text or apps, making them completely inaccessible to the people who need help the most.
The Solution
How It Works
ShambaLine gives every farmer access to an AI agricultural advisor through a simple phone call. Since 98% of the population has at least 2G or 3G signal, the platform works everywhere. Farmers call a local number, and an AI voice assistant guides them through their problem — no reading required, no internet needed.
Farmer Calls
Dials the ShambaLine number from any basic phone

Local telecom infrastructure intercepts and routes the call to the AI
AI Advisor Responds
ShambaLine AI conducts the conversation as a farming expert
All conversation data is saved to a database to improve the model and gather regional insights about the most common farming problems — potentially becoming the biggest farming research dataset in the region.
Lessons learned
What I Learned
- Designing technology for users with no digital literacy accessibility is more than just a checkbox.
- Building an AI voice assistant that works over basic telephony infrastructure, not just internet-connected devices.
- Conducting a full stakeholder analysis including farmers, telecoms, government, and IT providers.
- Thinking about real-world cost structures and how to make technology sustainable and affordable at scale.
- How AI can create genuine social impact in developing regions — not just tech for tech's sake.
