Problem

GrazeMate solves the labor, cost, safety, and coordination burden of moving cattle across large grazing properties. Traditional mustering can require helicopters, motorbikes, horses, and significant staff time; the company says Australian operations can spend more than $100,000 a year, while U.S. ranches may spend roughly $10,000 to $1 million. The killer use case is rotational grazing: moving herds between paddocks often enough to keep cattle on fresh grass, even when skilled labor is scarce, expensive, or difficult to retain.

Product / Service

GrazeMate, now rebranded as Brumby, provides autonomous drone operations through a mobile app. A rancher selects a destination or schedules a mission, after which the drone locates the herd, positions itself, and applies steady pressure to guide cattle between paddocks without an onboard pilot. Its reinforcement-learning software interprets animal behavior in real time and improves its handling of the herd over repeated moves. The same flights can locate and count cattle, estimate animal weights, measure pasture conditions, and inspect infrastructure such as fences and troughs.

The company’s model is to lease the drone and provide the software and end-to-end mustering support for a monthly fee, rather than sell hardware outright. Pricing is expected to depend mainly on ranch size and herd size, with the intended value proposition being a lower cost than conventional mustering, more frequent and better-managed grazing, reduced staff requirements, and less time spent on hazardous terrain.

Market

GrazeMate competes in agricultural robotics, autonomous livestock management, drone mustering, and precision-grazing software. Its closest operational alternative is conventional mustering with helicopters, motorbikes, horses, and human crews; adjacent technology competitors include SkyKelpie, which supplies fit-for-purpose drones, training, and supporting software for livestock producers, and CERES TAG, which uses satellite-connected livestock tags to monitor animal location, movement, and behavior. Those products primarily assist or monitor producers, whereas GrazeMate’s differentiator is autonomous intervention: actively moving the herd rather than only reporting where it is.

The company is an early-stage venture rather than a mature, publicly demonstrated revenue business. It raised a reported $1.2 million pre-seed round led by Y Combinator with participation from Antler and NextGen Ventures, and Forbes reported commitments covering 1.7 million acres in Queensland and New South Wales as it expanded toward California. As of the company’s July 2026 rebrand, Brumby said it was rolling out pilot programs and conducting extensive testing, so public evidence supports meaningful early validation and deployment commitments but does not disclose recurring revenue, named customers, or a completed commercial scale-up.
