Founders Fund leads $2B valuation round as Halter doubles down on its commitment to ranchers globally

Boulder, Colorado – Halter, the global agtech company transforming cattle farming, today announced it has raised $220 million in Series E funding at a $2 billion valuation. The round was led by Founders Fund, with participation from Blackbird, DCVC, Bond, Bessemer, NewView, Ubiquity, Promus and Icehouse Ventures, as it continues to expand alongside the ranchers using Halter in their operations.

The capital will be used to support the ranchers and farmers already using Halter and to extend it to more operations globally, with a continued focus on the people using it every day.

The round is one of the largest-ever in agtech globally and reflects growing demand for virtual fencing technology. Halter serves more than 2000 ranchers and farmers across New Zealand, Australia, and the U.S., with a million of its solar-powered collars now sold. Since launching in the U.S. in 2024, American ranchers using Halter have built 60,000 miles of virtual fencing as part of how they manage their land, with Halter working alongside them.

“We started Halter because we believed technology could fundamentally change what it means to run a ranch, and enable ranchers to use innovation to build long-term futures on their land,” said Craig Piggott, CEO and founder of New Zealand-born Halter. “Our ranchers need tools that work, and the fact that they’re using Halter tells us our technology has earned their trust. This raise lets us bring it to far more of them - and faster.”

The deep tech company’s GPS-enabled collars use audio cues and gentle vibrations to contain and herd cattle within virtual boundaries, allowing ranchers to move herds from a smartphone – without breaking ground or stringing wire.

“Agriculture is a multi-trillion-dollar industry that feeds the world, yet remains one of the least digitized sectors on earth,” said Founders Fund Partner Amin Mirzadegan. “Halter is changing that by bringing software, sensors, and AI directly into livestock operations in a way that ranchers actually adopt. Craig’s deep understanding of the ranchers he serves has enabled the company to build something that’s not just useful, but mission-critical to how ranches run.”

Halter will deploy the new capital to grow its commercial and field operations across the U.S., New Zealand, and Australia, while expanding into other international markets, starting with Ireland and the U.K. later this year. The company already has early ranches in Canada and is also exploring further expansion in North and South America this year.

Investment will continue across product development, including animal health monitoring and pasture management, shaped by how customers are using the system in the field. The focus remains on supporting the ranchers and farmers building their operations with Halter.
