What happened
Tencent already owned QQ, a huge desktop messenger, when smartphones arrived. Rather than simply port QQ, it let a small team led by Allen Zhang build a new mobile-first app, Weixin (WeChat), launched in January 2011. Features like voice messages and ‘people nearby’ made it feel native to phones, and it reached about 100 million users in just over a year.
The breakthrough in payments came at Chinese New Year 2014. WeChat let users send digital ‘red envelopes’ of money to friends and groups — a modern version of a deep tradition. Millions linked their bank cards in days, giving WeChat Pay a foothold against Alipay almost overnight.
In 2017 WeChat launched mini-programs: lightweight apps that run inside WeChat without downloads. Restaurants, retailers, governments, and games built on it. By 2023 WeChat had more than 1.3 billion monthly users and had become the default way many people in China message, pay, book, and shop.
