$2B AI cow collars use “cowgorithm” to herd cattle with no fences

by

A smart collar for cows, nicknamed the “cowgorithm,” is becoming increasingly popular after the company that makes it, Halter, recently received funding that valued the startup at about $2 billion.

According to a Bloomberg report, the New Zealand company is discussing a new round of funding led by Founders Fund, backed by Peter Thiel. This investment could raise the company’s value to around $1 billion. The company specializes in precision agriculture, utilizing artificial intelligence and smart collars to remotely monitor and manage cattle.

Halter collars are smart devices powered by the sun that help farmers manage their animals. They connect to a phone app, letting farmers see where their livestock are, check their health, and even guide them to new locations—all without needing fences or relying on things like farm dogs or manual work. The collars use gentle sounds and vibrations to move the animals instead.

This is incredible! Peter Thiel has invested $2 billion in a company called Halter, which makes a special collar for cows. The collar uses a unique software system, playfully nicknamed “Cowgorithm,” to manage and monitor the animals. Here’s how it works…

AI “cowgorithm” lets farmers control herds remotely

Okay, so this company has this really cool system they’re calling the “cowgorithm.” Basically, it lets farmers manage their whole herd super easily. I saw online that you can literally tap a button in an app, and all the cows move together! They wear these special collars that respond to the signals, so it’s like conducting an orchestra of cattle. Pretty wild, huh?

This technology constantly monitors animal health, including digestion and reproductive cycles, by using artificial intelligence learned from data collected from a vast number of animals. This helps farmers identify problems quickly and improve overall efficiency.

According to Halter, their system is currently being used in several countries, monitoring hundreds of thousands of cows. In the US, ranchers are using the collars as virtual fences, saving money they would have spent on traditional fencing by creating thousands of miles of it digitally.

This startup is joining a growing trend of ‘precision agriculture,’ using technology to automate farming tasks and make them more efficient. Although investment in agricultural technology has decreased recently, Halter’s success and high value indicate that people are still very interested in using artificial intelligence to improve farming.
