But they don’t answer the questions you actually have.\n\nFood is deeply personal, and so is Napkin Math:\n\n* Get the fuel you need for marathon training, while understanding you eat catered office lunches five days a week\n* Discover what’s triggering your stomach irritation, without sacrificing your weekly dinner with friends.\n\nNapkin Math tailors a plan for not only your specific health goal, but also your life.\n\n![uploaded image](/media/?type=post\u0026id=102010\u0026key=user_uploads/797433/1842f9f7-7918-4cc3-ab43-38de17ec30ba)\n\n### THE KEY INSIGHTS\n\n_Why hasn’t this been done before?_\n\n1. **Before AI, personalization was impossible**. Tailoring a plan to every chronic condition, allergy, goal, and stage of life was impossible. With frontier models, we’re able to reimagine nutrition experiences from the ground up.\n2. **We understand how to make taking a picture of your food fun.** How come Instagram foodies, who religiously follow “the camera eats first”, don’t also log their food in a journal? Napkin Math perfectly marries the joy of socially sharing food with a rich database that can help foodies feel better every day.\n\n### THE TEAM\n\nWe’ve been friends for a decade since living together at MIT. 🧑‍🧑‍🧒\n\n**Jynnie** worked on a games platform with 1MM players (Multiverse YC W20) and one of the largest Discord Games (Magic Circle, a16z Speedrun) — applying real gamification experience with AI to consumer health.\n\n**Manuel** has cracked product across consumer, healthcare, and hardware, recently leading Verkada’s largest product line — bringing AI to real problems.\n\n**Claire’s** work at Samsara through its IPO has given her insight into how tracking leads to safety outcomes for drivers, and now health outcomes for Napkin Math users.\n\nHappy Tummy, Happy Life 😉 [Try Napkin Math](https://napkinmath.club)","slug":"QXK-napkin-math-hyper-personalized-ai-food-journal","created_at":"2026-05-27T03:04:31.577Z","updated_at":"2026-06-20T16:35:59.079Z","total_vote_count":25,"url":"https://www.ycombinator.com/launches/QXK-napkin-math-hyper-personalized-ai-food-journal","share_image_url":"https://www.ycombinator.com/media/?type=post\u0026id=102010\u0026key=user_uploads/797433/1842f9f7-7918-4cc3-ab43-38de17ec30ba","company":{"id":31427,"name":"Napkin Math","slug":"napkin-math","url":"https://napkinmath.club","logo":"https://bookface-images.s3.amazonaws.com/small_logos/43a02b84a6b28b5fb26796fe822a596c638d433c.png","batch":"Spring 2026","industry":"Consumer","tags":[],"search_path":"https://bookface.ycombinator.com/company/31427"}}
