It was curious enough that OLIO, a UK startup with an app that lets users post a photo of unwanted food and share it with the local neighborhood, picked up $6 million in Series A funding back in 2018. Many outside observers wondered what was going on with this simple app, which looked on first inspection to be little more than a sort of community bulletin board about unwanted food. How could such a low-key idea have attracted such interest from serious investors like Accel? The answer is far more fascinating than its humble origins imply, and today founders Tessa Clarke and Saasha Celestial-One – who started OLIO out of frustration with food waste – prove they really might be onto something pretty big.
