Making cutting edge technology to help chefs reduce food waste
Winnow is a tech company making cutting edge technology to help chefs reduce food waste in the UK, Singapore, Dubaï, Shanghaï. Winnow connects commercial kitchens (Hospitality, hotels, restaurants and contract caterers) to the cloud allowing them to record and analyse exactly what is put in the bin. Food waste is an age old problem for the hospitality sector which up until now has not had an effective or scalable solution. Winnow helps the foodservice industry plan more effectively and cook smarter.
Simple and intuitive, the Winnow System has been designed specifically for busy kitchens. Winnow operates a software as a service (SAAS) business model and customers pay recurring license fee to access the cloud analytics and reporting platform. At the core of its commercial offering is the fact that Winnow offers an attractive ROI (Return On Investment) alongside its sustainability outcomes. By halving a kitchen’s food waste, Winnow reduces its food spending by 3-8%.
What gets measured gets managed, and by using data intelligently kitchens can be made more efficient.
