Our goal is to achieve 100% sustainable, healthy, affordable food for all. Madre Brava co-creates strategy, builds coalitions and powers campaigns to get there. Our secret sauce? We combine science, storytelling, and mobilisation to persuade companies, financiers, and governments to clean up the food we eat.

What we do and what we offer

We initiate cutting edge research to seed new ideas on food and climate change. 

We design and execute campaigns for industry transformation with our partners. 

We offer robust advice to policymakers and companies on food transition pathways.
