About Us
Food waste is a $1 trillion problem – costing the world more than 1% of global GDP. We're dead set on solving this problem and looking for people to help us achieve our mission. At Winnow, we believe that food is far too valuable to waste, and that technology can transform the way we produce food. Our team is made of people who all share a passion for food and technology.
Winnow was founded in London in 2013 to help the hospitality industry prevent food waste through Internet of Things tools in the kitchen. We have worked with thousands of sites and operate in over 90 countries with offices in London, Dubai, Singapore, Cluj-Napoca (Romania) and Chicago. Our blue‑chip customers include Accor Hotels, IKEA, IHG, Marriott, Compass Group and many others.
Our clients reduce waste by over 50% through our system, achieving 3%–8% food cost savings and 40%+ profitability gains. Winnow’s AI‑based vision technology tracks all food waste automatically and has been recognized by the World Economic Forum and other industry awards.
We are proud to have been listed in the 2025 Sunday Times Best Places to Work and to have won Impact 50’s most impactful companies award. Our culture is built on purpose, collaboration, and the belief that we should tackle real‑world problems while being great places to work.
