Our Story
The Founder
Hi, I’m John Cal Kelleher — a dairy farmer from mid-Cork in Ireland.
In 2019, we needed a GPS guidance system for spreading fertiliser, slurry, spraying, and mowing on our farm. At the time, I was finishing a year at the Ignite Business Incubator in University College Cork, where I had been developing an electric fencing monitoring system, which didn’t work 🤦.
So I went back to what I knew — farming — milking cows twice a day, and trying to solve a real problem on our farm.
When I started researching guidance systems, I found the same thing again and again: they were expensive, overly complicated, and not designed with everyday farmers in mind.
That got me thinking — could I build something better?
Something simple.
Something practical.
Something anyone could use — whether they grew up with smartphones or not.
I thought it would be easier to build than buy (I was wrong).
I thought no one else would want one (I was wrong).
And I thought I’d have moved on to a different idea by 2020 (I was wrong).
But sometimes being wrong is exactly what leads you in the right direction.
Where we’ve come from…
Based on a mid-Cork dairy farm in Ireland, we design, build, and supply our own tractor guidance systems.
We’re not coming from large-scale farms with massive fields — and that shapes everything we do.
Instead of building systems that try to do everything, we focus on what actually matters.
Reducing overlaps.
Avoiding misses.
Saving time.
Making everyday jobs easier.
We build simple, reliable guidance systems for real farmers.
What we’ve done…
Today, there are over 1,000 GyPSy Guidance Systems in use across Ireland, Northern Ireland, and the Netherlands.
We offer a range of systems designed for different jobs — all built with simplicity and reliability at their core.
If something goes wrong, support is straightforward and fast. Systems can be shipped or collected from our mid-Cork base, and when you call, you’ll be speaking directly to the people who designed and built your system.
We design GyPSy Guidance Systems.
We program GyPSy Guidance Systems.
We build GyPSy Guidance Systems.
We are GyPSy Guidance Systems.
With many thanks to the team at Ignite for their support and encouragement
