Summary
- Solar-powered collars create virtual fences for cattle management.
- System monitors animal health and fertility cycles, detecting illness.
- Halter's technology can increase land productivity by up to 20%.

New Zealand startup Halter has developed an innovative system using solar-powered collars to manage cattle herds through virtual fences. The technology, which gained significant backing from Founders Fund, enables farmers to remotely guide their livestock and monitor their health, including fertility cycles and signs of illness. This advancement allows for more efficient land use, potentially increasing productivity by as much as 20%.
Halter's solution involves a collar, a network of towers, and a smartphone app. Cattle are trained to respond to audio and vibration cues from the collar, learning to respect virtual boundaries within a few interactions. The system has been deployed on over a million cattle across more than 2,000 farms in New Zealand, Australia, and the United States.
The company's founder, Craig Piggott, emphasizes the system's focus on financial return for farmers. Halter's technology has achieved significant traction by demonstrating a strong return on investment, distinguishing it in an often-sluggish agricultural technology sector. Halter is now prioritizing expansion into South America and Europe, alongside continued growth in the U.S.
With a mission to manage the world's billion-plus cattle, Halter sees substantial room for growth. The company has raised approximately $400 million to date, aiming to reach more farms and develop further product innovations.
