Founders Fund backs AI cow collar startup Halter at $2B valuation in $220M round

What's the deal? New Zealand-based Halter has raised $220 million in a Series E round led by Founders Fund, valuing the agtech startup at $2 billion. Halter makes solar-powered, GPS-enabled smart collars for cattle that let ranchers manage and move herds remotely via smartphone, using virtual fences, audio cues, and vibrations — no wire or groundwork required.

The Auckland-based company, founded by Craig Piggott in 2016, now serves more than 2,000 farmers across New Zealand, Australia, and the US, with one million collars sold. Since its US launch in 2024, American ranchers have created 60,000 miles of virtual fencing.

Why now? Halter's previous round — $100 million at a roughly $1 billion valuation in June 2024, led by BOND — came just as it was prioritising US expansion. The new raise doubles that valuation, reflecting rapid commercial traction and an oversubscribed deal. The company plans to enter Ireland and the UK later this year and is eyeing further expansion across North and South America, with Canada already in early use.

Halter also plans to hire more than 200 people in its largest-ever recruitment drive, focused on product, engineering, and customer roles at its Auckland headquarters.

What could go wrong? Agtech has been a brutal category. A wave of startups has gone bankrupt in recent years as companies struggled to get farmers to adopt new technology while managing high operational costs. Halter's ability to scale globally — particularly into fragmented, cost-sensitive farming markets — while sustaining hardware and field-service operations will be a key test.

The signal: Agriculture is a multi-trillion-dollar industry, yet one of the least digitised sectors on earth, as Founders Fund partner Amin Mirzadegan noted when announcing the deal. Halter's raise is one of the largest in global agtech — trailing only Pivot Bio's $430 million in 2021 and Indigo Agriculture's $250 million in 2023. It signals renewed investor appetite for "precision agriculture" plays that can demonstrate real farmer adoption, not just technological promise.

The bet, at its core, is that software, sensors, and AI can become mission-critical infrastructure for livestock farming — and that Halter has found the formula to make that stick.
