Founded in 2021 in Perth, Rumin8 develops methane-abating feed additives for cattle by reproducing the naturally occurring compound found in red seaweed (asparagopsis) with a scalable manufacturing process. The company has shifted toward nature-inspired and derived pharmaceutical ingredients designed to reduce enteric methane while maintaining productivity and safety. Rumin8 is preparing to enter the final trial process for commercial registration of its additives and plans first commercial sales in New Zealand in 2027. It aims to decarbonise 100 million cattle by 2030 and is pursuing commercial partnerships, including a recent investment from AgriZeroNZ to support expansion into Aotearoa. Prior investors include Breakthrough Energy Ventures (Bill Gates), Harvest Road Group, Aware Super Sentient WA Growth Fund, and Prelude Ventures, following a reported $17 million seed round in 2023.
