Napkin Math
AI nutrition coach in your pocket
Operating in consumer based in San Francisco, CA, USA, Napkin Math operates.
Profile
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.
Within the consumer space, the company focuses on its core offering rather than a broad product line.
The company is recorded as being based in San Francisco, CA, USA.
Directory data places it at the Spring 2026 stage.
Recorded headcount: 3 employees.
Directory analysis
Napkin Math is a personalized AI food journal that gamifies nutrition tracking to boost user engagement. It tailors nutrition plans to individual needs—such as marathon training or office lunches—and helps users uncover triggers for stomach irritation. The service is built by a small team of three founders from MIT.
Positioning: As a niche consumer health app, Napkin Math differentiates itself by focusing on personalized nutrition insights rather than generic calorie counting, potentially appealing to users seeking deeper dietary understanding. With only three employees and no disclosed funding, it remains early in its growth trajectory within a crowded health app market.
Note: Napkin Math offers a gamified AI nutrition coach that tailors plans to individual eating habits.
