Sustainable Food Accelerator (Cohort 1)
A new 12-month, equity-free programme helping sustainable food ventures generate the technical, commercial and regulatory evidence that makes corporates confident to pilot, and investors confident to back. It's led in partnership by Undaunted, the Bezos Centre for Sustainable Protein and the Microbial Food Hub, delivered from Imperial College London's new Sustainable Food Hub.
Ventures get access to:
- Up to £100k equity-free funding, plus up to £2m in follow-on investment through Undaunted's investor network
- End-to-end scale-up infrastructure, from validation and process optimisation to pilot-scale production
- Corporate pilots with committed budgets through a global network of foodtech corporates and investors
- Regulatory and grant writing support, plus technical translation and business integration
Who should apply: Pre-Series A startups developing sustainable food tech, validated to approximately TRL 3-4, with a clear plan for technical and commercial validation. Founders should be able to commit to the 12-month programme and attend in-person sessions in London.
