Number 8 Bio

Number 8 Bio is a Sydney-based agtech and climate startup building BetterFeed, a low-cost feed additive and slow-release rumen bolus that cuts enteric methane from cattle and sheep by up to 90% in trials while recapturing wasted feed energy to lift animal productivity. After pivoting from yeast biomanufacturing to synthetic-chemistry small molecules, the company targets grass-fed grazing systems - about 95% of Australia's livestock - and has raised roughly A$18 million to move toward commercial release.
