Value proposition
Replaces physical fencing infrastructure with GPS-enabled virtual boundaries, enabling remote herd movement, 24/7 animal monitoring, and automated grazing management through a smartphone app—reducing labor requirements while improving pasture utilization and farm productivity.
Products and solutions
["Solar-Powered GPS Smart Collars for cattle","Virtual Fencing System with unlimited boundary creation","Halter Mobile App for remote herd management","Automated Cattle Shifting & Herding System","Real-Time Animal Health & Behavior Monitoring","Heat Detection & Breeding Cycle Tracking","Pasture Management & Grazing Optimization Tools","On-Farm LoRaWAN Communication Towers"]
Unique value
World-first patented Cowgorithm® AI algorithm that automatically trains cattle to respond to directional sound and vibration cues from collars, enabling virtual fencing without physical barriers. The system combines GPS positioning, LoRaWAN connectivity, and multi-sensor monitoring in a lightweight, solar-powered collar that works without cellular coverage.
Target customer
Beef ranchers and dairy farmers seeking to reduce labor costs, improve operational efficiency, and modernize livestock management across New Zealand, Australia, and the United States

["Agricultural Technology (AgTech)","Beef Cattle Ranching","Dairy Farming","Precision Agriculture","Livestock Management","Sustainable Agriculture"]
Technology advantage
Fully integrated hardware-software-AI platform that combines solar-powered GPS collars, proprietary long-range communication infrastructure, and AI-driven animal behavior training. The technology eliminates $15,000-$30,000 per mile costs of physical fencing while enabling precision grazing management, rotational grazing at scale, and real-time health monitoring. Over 100 engineers and designers develop the complete system in-house, creating strong technical moats in animal training algorithms, low-power electronics, and farm-specific UX design.
How they differentiate
Proprietary Cowgorithm® AI algorithm for automated cattle training with directional audio/vibration cues; full-stack in-house development (hardware, software, AI) with 100+ engineers; active herding capability beyond just containment; solar-powered collars with 5-year lifespan vs competitors' 6-9 month replaceable batteries; LoRaWAN connectivity enabling operation without cellular coverage in remote areas; U.S. Bureau of Land Management partnership ($2.7M) for federal public lands
