The United Nations estimates that 17% of the food available to consumers goes directly into the bin. Globally 923 million tonnes of food is wasted each year. 60% of this wastage happens in the home. Addressing this massive societal problem is London startup OLIO, a food sharing marketplace that lets neighbours share excess food by taking a photo, which is then available on the platform for neighbors to pick up. The simplicity of the app has made it quite popular; OLIO has handled 25 million+ portions of food and three million non-food household items that would have ended up wasted. The pandemic has served as a tailwind for the company, with a 5x increase in listing, as people reconsidered their relationship to the environment and sustainable choices. London TechWatch caught up with OLIO CEO and Founder Tessa Clarke to learn more about the genesis of the company, strategic plans, latest round of funding from investors that include VNV Global, Lugard Road Capital, DX Ventures (the venture arm of Delivery Hero), Accel, Octopus Ventures, and Rubio.
