Halter is a New Zealand-founded precision livestock company that has built an end-to-end system for managing beef and dairy cattle remotely. Each cow wears a solar-powered smart collar that connects to on-farm towers and a mobile app, allowing ranchers to create virtual fences, shift herds, and monitor animal health and behavior 24/7. The collars guide cattle using gentle sound and vibration cues rather than physical fences, while onboard sensors and AI models surface early signals of illness, heat, and calving. Halter's software turns continuous behavioral data into actionable insights that lift pasture utilization, animal welfare, and labor productivity. The company operates across New Zealand, Australia, and the United States, with a US base in Boulder, Colorado, and reached a $1 billion valuation in its June 2025 Series D.
