Eureka 191: Olio

Tessa Clarke is CEO and co-founder of Olio. It was the first app to allow neighbours to share food, which might otherwise go to waste. Since launch in 2015, more than 3.6 million portions of food have been shared by almost 2 million people in 49 countries. The company also has a dedicated network of volunteers who pick up food from local businesses to share with the community.
