About us<a href="https://www.forbes.com/sites/danagunders/2019/03/22/meet-the-smartest-trash-bin-yet/"></a>Food waste is a $1 trillion problem – costing the world over 1% of global GDP. We’re dead set on solving the problem and looking for people to help us achieve our mission. We, at Winnow, believe that food is far too valuable to waste, and that technology can transform the way we produce food. Our team is made of people who all share a passion for food and technology.Winnow was founded in London in 2013 to help the hospitality industry prevent food waste through internet of things tools in the kitchen. We have worked with thousands of sites and are operating in over 90 countries around the world supported by our offices in London, Dubai, Singapore, Cluj-Napoca (Romania) and Chicago. We are a scale-up stage company with a strong base of clients who are rolling out our system globally. We have blue-chip customers including Accor Hotels, IKEA, IHG, Marriott, Compass Group and many others.Winnow’s clients on average reduce waste by over 50% by value and sustain savings. Winnow works with hotels, universities and schools, staff restaurants, event/hospitality kitchens, buffets, pubs, and high street restaurants. Where the system is permanently adopted, pre-consumer waste value is reduced by 50% - 70% with no detrimental impact to the perceived quality or value of the offer to their customers. This represents a typical improvement of food cost savings of 3% to 8%, commonly a 40%+ increase in profitability for operations.As the global leader in addressing food waste, we are committed to continue pushing the envelope on what technology can do to solve this problem. Winnow Vision, our new artificial intelligence-based technology, is trained to automatically track all food waste thrown away. It has won awards at the World Economic Forum and has received tremendous enthusiasm from our clients and the industry.

Kitchens using Winnow know exactly what they're putting in their bins. At Winnow, we help the food service and hospitality industry cut down on food waste by making the kitchen smarter.With <a href="https://www.winnowsolutions.com/vision?hsLang=en" rel="noopener noreferrer" target="_blank">Winnow Vision</a>, our AI-enabled tool, kitchens can automatically track food waste. Winnow Vision uses computer vision to help chefs easily pinpoint waste, cut costs and save time. The system takes photos of wasted food as it's thrown away and, using the images, the machine trains itself to recognise what has been thrown in the bin. This means that, over time, food will be thrown in the bin and the data will be captured automatically. This increases data accuracy and ease of use.Simple and intuitive to use, the <a href="https://www.winnowsolutions.com/en/product?hsLang=en" rel="noopener noreferrer" target="_blank">Winnow Waste Monitor</a> comprises a digital scale and a connected tablet. Using any bin, team members throw food away in the usual way. The weight is recorded and then the user selects the reason and identifies the item/dish using the tablet.
