Temu draws on the same highly efficient and optimized network of suppliers in China that Pinduoduo has spent close to a decade developing. They combine that with a limitless pool of Chinese developers and an office in Boston that handles the legal and marketing end of things in North America. And you have a recipe for runaway growth.

Amazon tried something similar with their cultivation of Chinese sellers on Amazon marketplace but Temu takes this to another level.
