AI-powered food waste prevention for hotel kitchens
Occupancy swings night to night, but buffets, banquets, and room service still have to be ready regardless, so kitchens over-produce to stay safe. Winnow measures what actually gets thrown away, outlet by outlet, service by service. Hotel teams use it to protect F&B margin, meet guest expectations, and report progress with auditable data. The buffet still looks full.
Trusted by Hilton, Marriott, Accor, IHG, Mandarin Oriental and Four Seasons, in 90+ countries.

We’ve optimised portion control and quantity at the buffet station, making the food in smaller batches and refilling it more often. The food then arrives fresher and hotter to our guests which helps a lot with maintaining our high guest satisfaction scores.
