At Too Good To Go, we have an ambitious goal: to inspire and empower everyone to fight food waste together. 40% of all food produced in the world is wasted. And that has a huge impact on the health of our planet, with 10% of greenhouse gas emissions coming from food waste.  We’re more than an app: we are a certified B Corporation with a mission to empower everyone to take action against food waste, so alongside our marketplace app, we create educational tools, explore new business solutions - such as our Retail Technologies offering, and influence legislation to help reduce food waste. We’re growing fast: Our community of 114 million registered users and 261,000 active partners across 20 countries, have together already prevented 517+ million meals from going to waste - avoiding over 1.397.000 tonnes of CO2e! Your mission With our current scale and impact on the problem of food waste, it is vitally important that we continue to create a product that consumers love and a product that brings strong and ever-increasing value to our partners.
