Marc Zornes was a former McKinsey consultant where he was a leader in the consumer & sustainability practices. While at McKinsey, Marc co-authored the McKinsey Global Institute report on Resource Revolution. In developing this report, his team highlighted food waste as one of the biggest issues globally, and yet very little was being done about it.

Marc then left McKinsey to found Winnow. Marc founded Winnow to help the hospitality sector cut food waste using technology. Winnow builds artificial intelligence tools to help chefs run their kitchens more efficiently focusing on helping them understand and prevent food waste. Since launch, Winnow has been deployed in 70 countries and has saved its customers over $60m by reducing food waste. Clients include global brands like IKEA, Iberostar, ISS, and Hilton.
