The builder's path

Five steps from a problem to its solution.

For: Farmers in Kenya can't check at the depot whether a bag of fertiliser has passed quality tests.

Routes to a solution

Six ways to take this forward

Each route is a different kind of journey, with real people and organisations to contact at each step, starting with those in Kenya.

  1. Step 1

    Join an impact incubator

    Shape a model that pays for itself without excluding the people who need it.

Ideas to explore

  • Idea 1Batch check by SMSText the product name and batch number to a short code; reply with permit status and any recall, from a list kept up to date with bureau notices.

Help me design and build a first working prototype for this problem in Kenya.

Problem: Farmers in Kenya can't check at the depot whether a bag of fertiliser has passed quality tests.
Who it hurts: Smallholder maize and wheat farmers who buy subsidised fertiliser through government depots and agro-dealers.
The moment it hurts: Collecting bags at planting time, when a bad batch means a lost season.
What people do today: Farmers trust the standards mark printed on the bag. Problems surface months later through lab tests, recalls and news reports.
Why it is still unsolved: A printed mark can be copied, and test results and suspended permits are not visible to a farmer standing at the depot.
What solved looks like: A farmer scans or texts the batch number on a bag and gets back whether that product and batch have a valid permit and any failed test or recall, drawn from the standards bureau's records.
Where: Kenya

First, list what you would need to learn from the people affected before building, as interview questions.
Then propose the simplest version that would help, the screens or messages it needs, and the data it would use.
Keep it cheap to run, accessible, and respectful of people's privacy. Flag anything you are unsure about instead of guessing.
  1. Understand it

    Talk to the people who live it before you build.

    “The true creator is necessity, which is the mother of our invention.”

  2. Prototype with AI

    Get a working version in front of people fast.

    Using AI is not cheating. Every tool carries the work of the people who made it, and using it well is how knowledge has always moved forward. The thinking, the care for the people who live the problem, and the judgement are still yours.
