## About

Based in Sydney, Australia, Number 8 Bio provides precision fermentation using synthetic biology. As of 2023, the company is headed by its CEO Dr. Tom Williams (CEO), who co-founded the firm along with Dr. Alex Carpenter. In November 2025, Number 8 Bio Pty Ltd raised AUD 11 million in series A funding led by investor Icehouse Ventures, with participation from another investor ONE Innovators and Main Sequence Ventures also participated in the round.

The company offers precision fermentation to eliminate agricultural greenhouse gas emissions. Precision fermentation is a technique that is done using microorganisms, such as bacteria or yeast, to produce specific compounds or substances through fermentation.  It reduces ruminant methane emissions, saving money for our farmers, and saving our climate.

The company plans to utilize the November 2025 funding to accelerate commercialization of its methane-reducing livestock feed product and fund regulatory approvals for expansion into New Zealand and Europe.
