Zimplistic’s vision is to accelerate the world’s transition to eating healthy at home through smart technology and robotics. It’s flagship product, Rotimatic, enables users to make flatbreads with a touch of a button in flat 90 seconds. Consumerism has led to a shift in the eating habits where people are more reliant on supermarkets and frozen food because it is convenient and easy. Busy lifestyles and lack of time has led to a generation of ‘instant food’ that is loaded with preservatives and additives. With a vision of seamlessly integrating consumer robotics with IoT, we are working to bring about a day when families can eat healthy homemade meals with just the touch of a button. Zimplistic’s flagship product, Rotimatic is the world’s first and only fully automated, IoT and AI enabled kitchen robot that measures, kneads, rolls, cooks and puffs perfectly round flatbreads, every single time. It takes away the hassle of making flatbreads with hands and allows users to get creative without compromising on health. Rotimatic has already touched lives of 70,000 families around the world and has been instrumental in reversing unhealthy eating habits, one roti at a time.
