The collars use audio cues and gentle vibrations to contain and herd cattle within virtual boundaries, allowing ranchers to move herds from a smartphone without physical fencing. Halter raised $220 million in Series E funding in March 2026, led by Peter Thiel's Founders Fund, doubling the company's valuation to $2 billion in less than a year. This is the largest VC raise in New Zealand's history and one of the top 10 agtech valuations ever achieved. Total funding now exceeds $300 million. The company currently serves more than 2,000 ranchers and farmers across New Zealand, Australia, and the United States, having sold 1 million solar-powered collars to date. Each collar collects over 6,000 data points per minute, processed in real time for actionable insights. US ranchers have created over 11,000 miles of virtual fencing. Halter is planning its largest hiring effort of 200 people and expanding into Ireland and the UK later in 2026. ## Frequently Asked Questions ### What does Halter do?

This creates recurring revenue tied to farm size and herd count. ## Tags energy, b2b --- *Data from geo.sig.ai Brand Intelligence Database. Updated 2026-04-14.*
