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.
