At just 19 years old, Sam Rogers is building one of Australia’s most exciting agtech startups. Founder of GrazeMate, Sam is using autonomous drones, robotics, and AI to help farmers and ranchers move cattle, measure pasture, and gain real-time insights straight to their phone. In this episode, Sam shares his journey from growing up on a cattle station in North Queensland to raising capital, relocating to the US, and taking GrazeMate global. This conversation explores innovation in agriculture, resilience, robotics, and what the future of farming could look like when technology meets deep agricultural knowledge.

Episode Summary
In this episode of Humans of Agriculture, Oli Le Lievre sits down with Sam Rogers, the 19-year-old founder of GrazeMate, an agtech startup redefining how cattle are managed using autonomous drones and artificial intelligence.
Sam shares his remarkable personal story, growing up on a cattle property in North Queensland, competing internationally in robotics as a teenager, surviving a spinal tumour, and climbing peaks in Nepal. These experiences shaped his mindset and ultimately led him to build GrazeMate, a technology that helps farmers muster cattle, estimate liveweight, analyse pasture, and manage grazing with far greater efficiency.
The conversation explores Sam’s rapid rise in the agtech world, including global media attention, raising investment, relocating to California, and preparing to take the stage as a Groundbreaker at EvokeAG. Together, Oli and Sam unpack the opportunity agriculture presents for solving some of the world’s biggest challenges, the power of robotics at scale, and why the future of farming depends on aligning innovation with real on-farm needs.
This is a powerful story about curiosity, resilience, and the role young innovators can play in shaping the future of agriculture.
