Peter Thiel’s big bet on solar-powered cow collars
April 4, 2026
Peter Thiel's Founders Fund is investing in innovative companies like Halter, a New Zealand startup that has developed solar-powered smart collars for cattle management. Founded by Craig Piggott, Halter's technology creates virtual fences, allowing farmers to monitor and control grazing patterns remotely, which can enhance land productivity by up to 20%. The collars also collect behavioral data to track animal health and fertility, and have been adopted by over a million cattle across more than 2,000 farms in New Zealand, Australia, and the U.S. Despite its successes, the rise of AI-driven agricultural solutions raises concerns about animal welfare, data privacy, and the potential over-reliance on technology in farming. As Halter competes with other companies like Merck, the implications of these technologies on traditional farming methods and animal treatment require careful consideration. With approximately $400 million raised, Halter aims for global expansion, recognizing a vast market opportunity while emphasizing the importance of delivering strong financial returns to farmers for widespread adoption.
