Winnow’s war on waste

TECHCITYINSIDER100: Up to half of the food that’s grown globally is wasted. Winnow works with hospitality companies in hotels and restaurants to help them minimise this loss, which costs up to £2.5bn each year. Co-founder and chief executive Marc Zornes – a former McKinsey consultant – is driven by a desire to make the food supply chain more sustainable and help businesses become more profitable.
