Olio is a food-sharing app designed to reduce food waste by connecting neighbors and local businesses with surplus food to those in need. Users can share or request food items, making it easier to find and give away excess food that might otherwise go to waste. The app promotes community engagement and sustainability by encouraging people to share what they have. Founded in 2015 by Tessa Clarke and Saasha Celestial-One, Olio has grown significantly, with millions of users across various countries. The platform not only helps individuals but also supports local businesses in managing their food surplus responsibly, fostering a culture of sharing and environmental consciousness.
