What GrazeMate does

GrazeMate builds autonomous drones, marketed as robot cowboys, that herd cattle using AI. On command, the drones fly to a paddock, position themselves around the mob, and move the animals where they need to go, replacing work that traditionally relied on helicopters, motorbikes, and horses.

Key capabilities

  • Autonomous mustering using reinforcement-learning models that respond to cattle behavior in real time
  • Animal weight estimation and grass biomass measurement during herding
  • Water-level monitoring and flagging of sick animals
  • Scheduled, repeatable herding runs

Who it's for

GrazeMate targets cattle stations and livestock producers, particularly large operations where mustering is time-consuming and costly. Founded in 2025 in Sydney, Australia, by Sam Rogers, who grew up on a family cattle station, the company is part of Y Combinator's Winter 2026 cohort and has raised a $1.2M round with participation from investors including Meat & Livestock Australia.
