Founded in 2022 by Dr Tom Williams and Dr Alex Carpenter, Number 8 Bio develops innovative livestock feed solutions that reduce methane emissions and increase productivity. Its proprietary active ingredient is made in Australia from green chemistry, delivering a practical pathway to more profitable and sustainable farming.

Their platform technology models the rumen and enables rapid iteration from lab to animal trials in weeks rather than years, keeping solutions grounded in what actually works on-farm.

In 2025, Number 8 Bio raised AU$11m in Series A funding led by Icehouse Ventures. This raise will fund large-scale animal trials, regulatory approvals for expansion into New Zealand and Europe, and the rollout of a carbon-insetting program in Australia, enabling farmers and supply chains to claim verified emissions reductions.
