Company

Claire Nord is listed as a founder of Napkin Math. Napkin Math is the personalized AI food journal that people love to use. We gamify nutrition tracking so people are 2x more likely to stick with us than other trackers. Claire, Manuel, and I (best friends for 10 years from MIT) are obsessed with how we can make nutrition fun, and turn fun into health outcomes. === Existing consumer health apps focus on scaling a one-size-fits-all solution: calorie deficits. But they don’t answer the questions you actually have. Food is deeply personal, and so is Napkin Math: Get the fuel you need for marathon training, while understanding you eat catered office lunches five days a week. Discover what’s triggering your stomach irritation, without sacrificing your weekly dinner with friends. Napkin Math tailors a plan for not only your specific health goal, but also your life.
