Which e-commerce company was founded by Colin Huang in 2015?

Colin Huang founded the e-commerce company Pinduoduo in 2015.

Pinduoduo was established in China and became known for combining online shopping with social interaction. Its group-buying model encouraged users to invite friends or other shoppers to purchase products together, often unlocking lower prices. This approach helped the platform attract price-sensitive users and spread through social networks.

The company differed from a conventional search-and-buy marketplace because participation and sharing were central parts of the shopping experience. It also emphasized agricultural products and direct connections between producers and consumers, alongside general merchandise.

Pinduoduo later expanded internationally through Temu, a separate consumer-facing marketplace launched by its parent company PDD Holdings. Pinduoduo is sometimes confused with JD.com or Alibaba’s Taobao, but those platforms have different founding histories and operating models.
