Growing up as the daughter of food business owners, Govani’s earliest memories are ones of scooping ice cream at the family ice cream shop. Working at her parents’ neighborhood markets in New Jersey provided an early education on the connection between cheap, processed food and obesity. In retrospect, these experiences fueled many of her business and personal pursuits.
After earning her Economics and Psychology degree from NYU, Govani went on to build a successful career in consumer, behavior-driven product development. She spent 5 years at American Express, where she achieved award-winning recognition and earned herself a patent. She went on to a green-tech startup focusing on building products and tools to help people live more sustainable lives. She then joined Purpose, a social impact incubator, to build out a food systems solution that leveraged the power of community engagement to drive support for a healthier, more sustainable food future. Foodstand, Inc. was born out of that incubator and went on to inspire healthy, more sustainable eating in thousands of people in 85 countries.
Rachna has spoken widely on food systems issues, food waste, behavior change, and social entrepreneurship, and has been featured in Food & Wine, Forbes, Edible, Fast Company, and USA Today, just to name a few. She lives in metro Detroit with her partner and two children and can be found in her kitchen or perusing the local farmer's market.
