About LemonBox

LemonBox is a health tech brand specializing in AI-Generative Personalized Nutrition. Founded in Silicon Valley in 2016, the brand officially entered the Chinese market in 2018 as a Y Combinator-backed startup. Currently headquartered in Shanghai, LemonBox also maintains offices in Hong Kong and San Francisco. LemonBox operates on a dual-layer technical architecture of "Cognitive Generation and Physical Delivery". At the cognitive layer, it leverages large AI models to analyze multi-dimensional user data—including diet, lifestyle, and medical check-ups—to dynamically generate digital, personalized health intervention reports and nutritional advice. At the execution layer, it relies on its proprietary LemonAlgo™ (AI-Driven Adaptive Engine) and Personalization Fulfillment Center (PFC) to translate these digital formulas into daily, individually packed physical vitamin packs delivered straight to users. As of 2026, LemonBox has served over 10 million users. Its institutional investors include Y Combinator, Partech Ventures, and others, with total funding exceeding 100 million RMB. In addition to its consumer focus, LemonBox also provides AI-driven personalized nutrition and wellness solutions to enterprise (B2B) clients. As a pioneer in the AI-generative personalized nutrition sector within the Chinese market, the company has been recognized by the Youth Daily as a trailblazer in the field.
