Peter Thiel Invests in Halter and Its AI Collars for Cows

The Founders Fund, led by the influential Peter Thiel, is considering financially supporting Halter, an innovative agritech company from New Zealand. According to a Bloomberg report dated March 20, 2026, this startup could be valued at around $2 billion. Halter stands out in a declining sector thanks to its smart solar collars, which create "virtual fences" to guide herds via a mobile app. This simple and intuitive technology is attracting attention in a market where agritech is losing momentum.

Halter was founded by Craig Piggott, an engineer who honed his skills at Rocket Lab. The company's goal is to improve the productivity and sustainability of farming practices through technological innovations. Halter's flagship product is a solar-powered collar that integrates advanced technologies such as GPS and various sensors. These collars allow farmers to guide cows using sound signals and vibrations, thus facilitating herd management.

Collar Features

The collar developed by Halter incorporates software called "Cowgorithm." This program continuously analyzes data related to the animals' movement, digestion, activity, and fertility. With this information, certain decisions can be automated, such as moving herds, detecting health issues, or optimizing pasture rotation. Farmers can thus gather their animals remotely, without needing to intervene physically.

Halter's business model is based on a subscription system per animal, with costs ranging from $5 to $8 per month per cow. This model has been refined over nearly ten years, with commercial beginnings in New Zealand in the early 2020s, before expanding into the American market.

Market Context

Halter operates in an agritech sector that is currently facing challenges, including a decline in funding, a series of bankruptcies, and often unprofitable business models. Despite these challenges, Halter seems to be carving out a niche by offering a tangible and understandable product based on AI. It remains to be seen whether this algorithmic approach will convince farmers, who are often cautious about new technologies, and whether the model can scale effectively. Peter Thiel's role in this dynamic could also influence the future of this promising company.
