Rachna was the CEO and Co-founder of FOODSTAND, a public health tech company committed to making healthy eating an everyday habit for the masses. Through community-powered, Healthy Eating Challenges, FOODSTAND helped tens of thousands of people in over 85 countries change their eating habits to curb the onset of diet-related diseases.

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’ bodegas 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.

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 son, and can be found in her kitchen or perusing the local farmer's market.
