Halter’s solar-powered cattle collars are on one million animals — the real asset is the dataset underneath

Halter, a New Zealand agtech startup, makes solar-powered smart collars for cattle. The company has raised $220 million in a Series E round led by Founders Fund, valuing it at $2 billion. Halter's collars replace physical fences on pasture-based farms, enabling precision grazing control and productivity gains of up to 20%. The collars also track cattle health and behavior, generating a substantial dataset. With over one million collars deployed across thousands of farms, Halter is prioritizing expansion into South America and Europe. The company's dataset has potential applications in precision agriculture, breeding optimization, and parametric insurance models.
