Robot Cowboys that Herd Cattle with AI Drones

GrazeMate builds autonomous drones that herd cattle. At the push of a button, our AI drones fly to a paddock, position themselves around the herd and guide them to new paddocks. Instead of a full day mustering with helicopters, motorbikes, and horses, ranchers use GrazeMate. We work with the world's largest cattle ranches, giving them complete visibility into their operations. While our drones herd cattle autonomously, they simultaneously estimate animal weights, measure grass biomass, monitoring water levels, and detect sick animals. We're building physical AI that gives farmers superhuman capabilities - managing thousands of livestock across massive distances from their phone.

GrazeMate: Drones that Herd Cattle
See original launch post

TL;DR - Ranchers can spend hundreds of thousands per year moving cattle between fields. GrazeMate builds autonomous drone software to guide cattle - doing the work of helicopters and motorbikes with AI that understands animal behaviour.

❌ The problem

I'm Sam. I grew up on my family's cattle station in Australia, where we move cattle on motorbikes, helicopters, and horseback. It took hours each day and >$100k/year.

In the US, ranches spend anywhere from $10k–$1M per year and hours each day moving cattle just to keep them on fresh grass. It's expensive, risky, and hard to staff.

✅ The solution

GrazeMate's autonomous drones herd your cattle for you. What could take teams a full day now takes three clicks from a phone.

Our system:

  • Finds your herd and guides them calmly to the next pasture
  • Uses AI that reads animal behaviour and applies pressure like an experienced stockman
  • Learns how your cattle respond and improves with every move

Why ranchers are switching:

  • More frequent moves → Better grazing, pasture use, and stocking rates
  • More affordable than traditional methods
  • Hours of herding → seconds on a phone
  • Real-time weight estimates, pasture data, and infrastructure insights

🤠 Why us

My family runs 6,000 head. I dropped out of robotics at University of Sydney after seeing both the challenges with modern ranching, and the capacity robotics has to help. Our team combines PhDs and engineers who grew up on ranches.

🙏 Our ask

We're onboarding early partners. We’d be extremely grateful for introductions to:

  • Large grazing operations (US and beyond)
  • Ranch managers exploring rotational grazing
  • Industry leaders, cattle agents, feedlots, processors

And if that’s you, schedule a demo on grazemate.com, or contact me at sam@grazemate.com. I’d love to chat!
