During his nearly two decades at JD.com, Yishen Tang witnessed and shaped many of the defining moments of China’s e-commerce and retail evolution. From telecommunications and automotive to fresh food, he led businesses from 0 to 1, managed large-scale teams, and operated at a billion-RMB scale — gaining deep experience in platform efficiency, scale, and supply chain integration.

Yet at the peak of his career, he made an unexpected “reverse choice”: leaving the platform to start from scratch and build a highly focused low-GI food brand, Detective 55.

Since its founding in 2022, from launching its first low-GI oat bran product to gradually expanding its portfolio, building an integrated supply chain, and introducing its 2.0 brand upgrade with the concept of “intelligent glucose control,” Detective 55 is not a business driven by rapid scale. Instead, it represents a long-term commitment to health, patience, and sustainable value creation.
