Ruminant Biotech has secured fresh backing to accelerate the fight against livestock emissions, a major contributor to global warming. The New Zealand agritech company has closed a $9.7 million Series A round to advance its methane mitigation technology for pasture-based cattle. The funding comes as livestock methane is estimated to account for around 6 percent of human-caused greenhouse gas emissions worldwide, putting pressure on agriculture to adopt scalable climate solutions.
Series A Funding to Scale Methane Reduction
The Series A round was co-led by Rosrain Investments and Cultivate Ventures, with significant participation from global financial services platform Marex and follow-on capital from existing investor AgriZeroNZ. Ruminant Biotech plans to use the investment to commercialize what it describes as a high-impact, long-duration solution that reduces methane emissions from pasture-based cattle. The company aims to launch its first product in Australia and New Zealand in 2026, building on more than $6.2 million in earlier grants that supported development and early regulatory work.
Technology and Commercialization Plans
Ruminant Biotech positions its solution as the first and only long-lasting methane reduction technology tailored specifically for pasture-based systems, which dominate markets such as New Zealand and parts of Australia. The product is designed to deliver sustained emissions cuts without disrupting existing grazing practices, an important factor for farmer adoption. With the new capital, the company will scale manufacturing, refine deployment models with industry partners, and prepare for commercial rollout across key livestock regions in Australasia.
Global Regulatory Pathway and Market Expansion
Beyond its home markets, Ruminant Biotech plans to accelerate regulatory approvals in major cattle-producing regions including Brazil, Canada, the United States, the United Kingdom, and the European Union. Unlocking these jurisdictions would allow the company to address a materially larger share of global livestock methane emissions. The firm is also investing in further technology development to adapt its solution to additional cattle market segments, widening its potential customer base over time.
Investor Support and Carbon Market Opportunity
For investors, the appeal lies not only in climate impact but also in the growing demand for credible agricultural carbon credits. Marex, which is expanding its carbon markets offering, views Ruminant Biotech’s technology as a way to secure access to high-quality credits for clients while supporting on-farm emissions reductions. AgriZeroNZ’s decision to reinvest signals continued confidence from New Zealand’s sector-focused backers, reinforcing the view that methane mitigation in livestock is becoming a core component of future agricultural productivity and value chains.
The Series A round marks a significant milestone for Ruminant Biotech as it moves from research and pilot phases toward large-scale commercialization. If successful, its methane reduction solution could give farmers in pasture-based systems both an environmental tool and a new revenue stream linked to carbon markets. With product launch targeted for 2026 and a clear global expansion roadmap, the company is positioning itself as a key player in the transition to lower-emissions livestock production.
