Halter secures $220 million at a $2 billion valuation to expand its virtual fencing technology.

      A cow equipped with a GPS collar may not seem like a $2 billion concept. However, for ranchers who have established virtual fences across 60,000 miles of American pastureland in less than two years, it evidently is.

      Halter, an agtech firm from New Zealand, announced on Monday that it has secured $220 million in Series E funding, reaching a valuation of $2 billion. The funding round was led by Founders Fund, the firm of Peter Thiel, which initially invested in Halter during its Series A round in 2017 and is now reaffirming its support nearly a decade later. Other existing investors including Blackbird, DCVC, Bond, Bessemer Venture Partners, NewView, Ubiquity, Promus, and Icehouse Ventures also contributed.

      This funding constitutes one of the largest amounts ever raised in the global agtech industry, valuing a company that fundamentally produces solar-powered collars for cattle.

      Functionality of the collar

      Halter’s GPS-enabled collars utilize audio signals and gentle vibrations to manage and guide herds within virtual boundaries. Ranchers can adjust fence lines from their smartphones, allowing them to move cattle across different segments of land without the need for physical barriers, wire, or even being present in person. This system replaces one of the most traditional and expensive ranching infrastructures with software.

      Currently, the company claims to have sold one million solar-powered collars and serves over 2,000 ranchers and farmers in New Zealand, Australia, and the United States. Since their US launch in 2024, American ranchers have implemented 60,000 miles of virtual fencing through the platform, a figure that had been reported as 11,000 miles in November 2025, indicating a rapid increase.

      Purpose of the funding

      The funds will support Halter’s ongoing expansion of commercial and field operations in its three existing markets while also opening two new ones. Ireland and the United Kingdom are expected to be added later this year, with initial ranch implementations already commencing in Canada and further expansion being considered across North and South America.

      Halter is also planning its largest hiring initiative to date, adding over 200 new positions focused on product development, engineering, and customer service at its headquarters in Auckland.

      On the product front, the company is investing in capabilities for animal health monitoring and pasture management, building on the foundational virtual fencing system to create a more extensive operating layer for livestock management.

      Transition from unicorn to double unicorn

      The company’s growth trajectory has been steep. In June 2025, Halter secured $100 million in a Series D funding led by Bond, achieving an approximate valuation of $1 billion, marking it as one of the few deep tech companies to reach unicorn status outside major tech hubs. Within less than a year, the valuation has doubled.

      This rapid advancement indicates more than mere hype. Halter is involved in the livestock management sector, worth trillions globally, yet remains one of the least digitalized industries. The virtual fencing market hardly existed five years ago, but it is now attracting investments from the same backers of notable firms like SpaceX, Palantir, and Stripe.

      Amin Mirzadegan, a partner at Founders Fund, pointed out a common challenge for deep tech firms in agriculture: adoption. Many agtech startups struggle with consistent product delivery to farmers. Halter, he observed, has developed a solution that ranchers are not only willing to use but have also integrated into their daily operations.

      The more challenging question

      Agricultural technology has a history of making lofty promises but achieving limited adoption. The sector drew billions in venture capital during the early 2020s, much of which was aimed at indoor farming, food delivery logistics, and biotech strategies that later faced scaling challenges. Virtual fencing stands apart as it addresses an immediate, practical issue by replacing traditional infrastructure; however, it still grapples with convincing a conservative industry to trust technology over conventional methods.

      Halter's strategy has been to immerse itself within ranch operations rather than selling from a distance. The company employs field teams that collaborate closely with its customers, a labor-intensive approach that has facilitated adoption, but will need to be efficiently scaled as they expand across six or more countries.

      Craig Piggott, who founded the company in New Zealand and now leads it from Boulder, Colorado, emphasized that the funding is fundamentally about the current users of the product. He indicated that the capital enables Halter to reach more ranchers more quickly.

      Whether a collar on a cow can sustain a $2 billion valuation will depend on whether this outreach results in the kind of consistent, vital adoption that transforms an innovative piece of hardware into an industry standard. The one million collars sold is just the beginning of that story; the next million will provide further insights.
