LemonBox

LemonBox (来檬) is a health-technology brand working in AI-generative personalized nutrition. Founded in 2016 in Silicon Valley, incubated at the University of Chicago Polsky Center in 2017, and accepted into Y Combinator in 2018, it entered the Chinese market that year and is now headquartered in Shanghai. LemonBox builds individualized daily vitamin and supplement packs from a three-minute FFQ (food frequency questionnaire) nutrition assessment scored by its LemonAlgo adaptive engine, then fulfills them one pack at a time (MOQ=1) through its Personalization Fulfillment Center in Hong Kong. The company reports serving more than 10 million cumulative users as of 2026 and sells both direct-to-consumer and B2B. Investors include Y Combinator and Partech. LemonBox operates a consumer web and WeChat mini-program experience and publishes no public developer API, SDK, or developer portal; its agent-facing surface is limited to a published /llms.txt and a robots.txt that explicitly allow-lists generative-AI crawlers.

LemonBox is profiled on the APIs.io network. Tagged areas include Company, Consumer, Health, Nutrition, and Supplements.
