Helping to reduce food waste in kitchens with the help of cutting-edge AI technology, our Startup of the Week for this week is Winnow!

Winnow was founded in 2013, started on the belief that food is far too valuable to waste – food waste costing hospitality more than $100bn annually. According to Winnow, kitchens can waste what is often the equivalent of their total net profits, as staff can commonly lack the tools to manage and measure their waste accurately.



Winnow have two products to help organisations calculate, and thereby manage, their food waste. These being:

Winnow Vision – helps to identify food waste in a kitchen, gathering information on what’s thrown away to produce valuable insights on the user’s food waste. Overtime, as more and more data is collected by Winnow Vision, the tech becomes smarter and better able to recognise what’s being thrown away, reaching a semi-automotive state, and thereby helping to reduce human error.

Winnow Waste Monitor – a digital scale also helping to provide valuable insights for kitchens regarding their food waste. Users simply throw waste away in a bin placed on Winnow’s smart weighing meter technology, before recording the item being thrown away on a simple touchscreen. After this, cloud software will analyse and record waste from throughout the day to provide users will powerful insights.

So far, Winnow have helped to save a total $42,000,000, 36,512,500 meals and 61,000 CO2. The startup have also raised $31.9 million over 6 funding rounds, their latest funding in 2019 raising a combined $20 million from a Series B and a loan from The European Investment Bank.
