AI is steadily making its way into agriculture, and Halter is one of the companies pushing that shift. Bloomberg has reported that the startup has secured fresh funding led by Peter Thiel’s Founders Fund, taking its valuation to $2 billion. The company focuses on GPS-enabled collars for cattle, using software and machine learning to manage livestock without relying on fences or traditional herding methods.How the technology works

Halter’s system is built around a wearable collar placed on each cow. The device uses GPS and solar-powered hardware to guide animals using sound and vibration cues. Farmers can control herd movement through a mobile app, allowing them to direct cattle toward milking stations or grazing areas without manual intervention.

Cowgorithm: The software layer behind herd automation

The company has branded its software system as the “Cowgorithm,” which uses data collected from animals to automate decision-making on farms. According to the information shared, large groups of cattle can be moved simultaneously using the system.

Monitoring and data-driven farming

Beyond movement control, the collars track health and behavioural patterns. The system monitors digestion, fertility cycles, and general activity levels in real time. This data is processed using machine learning models trained on large datasets of animal behaviour.

The aim is to provide farmers with continuous insights, enabling early detection of health issues and improving herd management efficiency.

Adoption and scale

The technology is already in use across multiple countries, with hundreds of thousands of cows connected to the system. Farmers in the United States have reportedly used the platform to create over 11,000 miles of virtual fencing. This replaces physical barriers and reduces infrastructure costs.

Estimates suggest that the use of virtual fencing has helped save significant spending that would otherwise go into building and maintaining traditional fences.

Halter operates on a subscription-based model, charging farmers between $5 and $8 per animal per month. This creates a recurring revenue stream tied directly to the number of animals using the collars.

The approach also increases long-term customer retention, as farm operations become integrated with the platform over time.

Background and funding

The company was founded by an engineer with a background in aerospace, including work at Rocket Lab. The latest funding round doubles Halter’s previous valuation of $1 billion, reflecting growing investor interest in agricultural technology.

The investment highlights a broader trend of applying AI and automation to traditional industries such as farming, where efficiency and cost control remain key priorities.
