Technology for a smarter farm

Putting you in the driving seat

We provide a herd management and virtual fence solution that reduces a complex and time-consuming job to just a few swipes of a screen.



Our custom-developed neck band, or Hoop, is solar powered and GPS-enabled. It uses audio cues to direct cows to stay within a predefined (and alterable) perimeter, or guide them to a set location.



Our team of farmers and leading tech developers have created Helm, an app that uses our unique “Cowgorithm” technologies. It will give you valuable insights and real time data to help you make informed decisions.


Developed for farmers by farmers

Here's how Halter works on the farm:

Halter will automatically bring the main herd to the cow shed for milking at 4:20am every morning.


After milking, the herd is shifted to paddock 03 without you walking behind them.

Easily set break feed boundaries by drawing a line across the paddock to optimise your pasture management.


Halter alerts you that that cow 31 is walking slower than usual and hasn't been as active as normal.

Using Halter collar you can reroute her so she's nearby when the farmer is available.

Halter establishes boundaries around waterways which means you don't have to worry about fences.

Frequently Asked Questions


What happens if the cow doesn’t respond to the sound?

If a cow crosses a boundary it receives an intermittent electric pulse. Cows learn to associate the audio cue with the pulse. Within an hour, the average cow learns the cues, and can be herded remotely.

Are you signing pilot farms?

Yes, we are. Fill in the form here to apply to join the Halter pilot farm programme.

How strong is the pulse?

The pulse is a quarter of that of an electric fence - directing the cow back to the set perimeter. This pulse is only used as a training tool until the cow responds to audio cues.
