KOSHI
A second brain for the agri-input retailer.
An agro-input shop sells seed, fertiliser and crop protection to the farmers of a few villages, mostly on credit, mostly from memory. The farmer walks in when a need arises. The retailer who knew which farmer sowed what, and when, could reach out first with the right product in the right week, but nobody could hold that in their head for three hundred farmers.
KOSHI holds it for him. It went from fifty shop conversations to the Play Store in ten weeks, and seven hundred retailers signed up.
Before
- Bills on paper, credit in a notebook, farmers in the retailer's memory.
- No way to know who is due for which input this month.
- Posters made by a designer in town, days later, often with the wrong price.
Now
- Billing, credit and farmer books on the phone, in Gujarati.
- Crop calendars for a hundred crops across Gujarat's five zones, so the app knows which stage each farmer's field is at and which input it needs.
- Posters generated from a photo of the pack and checked before they go out.
- A calling team and tutorials for shops that stall after sign-up.
How it went
Fifty shops before a screen
What a retailer does all day, where the money leaks, what he would actually use. The feature list came from the counter.
Ten weeks to the store
A weekly goal shared by product, design, content and the calling team, run in Linear.
Pilot shops in five regions
Saurashtra, North Gujarat, South Gujarat, Kutch and Middle Gujarat, so the calendars and the words were right for each belt.
Measure before launch
GA4, Firebase and the ops console wired up before launch day, so the week's story was in numbers by Friday.
Read the week honestly
Five hundred and seventy sign-ups, four in five through onboarding, one in three doing real work. Then the drop once hand-holding ended.
Act on it
A call-and-tutorial program that reached three hundred shops, instead of another feature.
What came of it
- Seven hundred retailers signed up in the first weeks.
- The retention finding became the plan for the next month, and the calling team can now onboard a shop without the product manager on the line.
