Halter

New Zealand agtech company whose solar-powered cattle collars replace physical fences, letting farmers move and monitor herds from an app.

Halter was founded in Auckland in 2016 by Craig Piggott, who grew up on a dairy farm in Matamata and set out to solve a problem every pastoral farmer knows well: physical fencing is expensive, slow to move, and doesn't tell you anything about how your animals are actually doing. The company's core product is a solar-powered collar, worn by each cow, that uses sound and vibration cues to steer animals within virtual boundaries a farmer draws in an app, replacing or supplementing electric wire and hand-shifted breaks. Each collar streams thousands of data points a minute back to Halter's platform, which farmers use to shift herds between paddocks remotely, detect heat cycles and early signs of illness, and get real-time location on every animal without walking the farm. The company has more recently added direct-to-satellite connectivity so the system works beyond cellular range, and reports deployment on several hundred thousand cattle across dairy and beef operations in New Zealand, Australia, and the U.S. Halter raised $220 million in a Series E round in March 2026 led by Founders Fund at a reported $2 billion valuation, following a Series D roughly a year earlier, and has said it plans to add more than 200 roles across its three markets as it scales manufacturing and support.
