Halter, a New Zealand company that makes solar-powered GPS collars for cattle, announced on 24 March 2026 that it had raised $220m in a Series E round at a $2bn valuation. Founders Fund led the round.
Blackbird, DCVC, Bond, Bessemer Venture Partners, NewView, Ubiquity, Promus and Icehouse Ventures also took part. Founders Fund had previously backed Halter in its Series A in 2017.
The Next Web reported that the valuation was double the roughly $1bn at which Bond led a $100m Series D in June 2025. The company described the new round as one of the largest in agricultural technology globally.
“Agriculture is a multi-trillion-dollar industry that feeds the world, yet remains one of the least digitized sectors on earth. Halter is changing that by bringing software, sensors, and AI directly into livestock operations in a way that ranchers actually adopt.”Amin Mirzadegan, Partner, Founders Fund
What Halter does
Halter's collars use sound cues and gentle vibrations to keep cattle inside virtual boundaries and to herd them, so farmers can draw fences, move animals and monitor their herds from a smartphone app instead of building and moving physical fences.
The company said it serves more than 2,000 ranchers and farmers in New Zealand, Australia and the United States and has sold one million collars. Since it launched in the US in 2024, American ranchers using Halter have built 60,000 miles of virtual fencing, up from 11,000 miles reported in November 2025, according to The Next Web.
Halter was founded in New Zealand by Craig Piggott, who is chief executive. The company has its headquarters in Auckland, an office in Melbourne and a US office in Colorado, and The Next Web reported that Piggott now runs the business from Boulder.
What the money is for
Halter said the money would support existing customers and bring the product to more operations. It plans to grow its commercial and field teams in the US, New Zealand and Australia and to enter Ireland and the UK later in 2026. It also has early customers in Canada and is looking at other markets in North and South America.
The company will spend on new products, including animal health monitoring and pasture management tools. It plans to hire more than 200 people, mostly in product, engineering and customer roles at its Auckland headquarters. Halter did not say how many people it currently employs.
Why investors backed it
Amin Mirzadegan, a partner at Founders Fund, said in the announcement that agriculture remains one of the least digitised industries and that Halter had built something ranchers actually adopt. He said the product had become mission-critical to how ranches run.
Piggott said Halter was started on the belief that technology could change what it means to run a ranch, and that farmers' use of the product showed it had earned their trust.
With the Series D and Series E, Halter has disclosed $320m of funding since mid-2025. The size of its earlier rounds was not given in the sources, and the company did not state a total raised to date.
