Zoe launches new crowdfunding campaign to expand microbiome research

Nutrition science company Zoe has announced the launch of a new equity crowdfunding campaign as it looks to accelerate its mission of transforming gut health at scale.

The campaign, which is live on Crowdcube from today (2 October) until 24 October 2025, will support Zoe’s ambition to map more than one million microbiomes. This dataset will feed into the company’s proprietary AI platform, GutEngine, to generate new insights into the links between gut microbes and markers of health such as inflammation, cholesterol and fat distribution.

Zoe has already built what it says is the world’s largest microbiome health database, based on over 300,000 completed tests including microbiome, blood sugar and blood fat results. The new campaign follows a record-breaking Crowdcube campaign in 2022 that attracted more than 12,000 investors and set new benchmarks for female investor participation.

The latest fundraiser coincides with the launch of Zoe’s redesigned app, which delivers personalised nutrition insights powered by AI. The platform now allows users to receive guidance without undergoing multiple at-home tests, while still offering a new microbiome test for those who want deeper personalisation.

Since its last fundraising round, Zoe has scaled its reach to more than 3 million people per month, published 75 peer-reviewed papers, launched products such as the Daily30+ tool and the Zoe Gut Shot, and completed a randomised clinical trial published in Nature Medicine in 2024, which demonstrated Zoe’s effectiveness over traditional dietary advice.

Jonathan Wolf, Zoe co-founder and CEO, said: “This isn’t growth for growth’s sake. It’s about building something that lasts. Big Food still controls what most people eat, regulators move too slowly and the system is broken. If we want to fix it, we can’t wait. This fundraise allows our members to take matters into their own hands and be part of shaping the future.”

Professor Tim Spector, co-founder of Zoe, added: “Your gut holds the key to your health. Today, we’re closer than ever to unlocking its full potential. Together, we’re transforming microbiome research into real-world results that can help people live better, longer lives.”
