Alibaba

Alibaba Group Holding Limited (NYSE: BABA) is China's biggest online commerce company which provides consumer-to-consumer, business-to-consumer and business-to-business sales services via web portals. Its three main sites — Taobao, Tmall and Alibaba.com — have hundreds of millions of users, and host millions of merchants and businesses. Alibaba handles more business than any other e-commerce company.

The firm was launched in 1999 when Jack Ma founded the website Alibaba.com, a business-to-business portal to connect Chinese manufacturers with overseas buyers. In 2012, two of Alibaba’s portals handled 1.1 trillion yuan ($170 billion) in sales.

In 2014 Alibaba became one of the most valuable tech companies in the world after raising $25 billion from its U.S. IPO. It is also one of the most valuable Chinese public companies, ranking among some of the country’s state-owned enterprises.
