(Yicai Global) Oct. 22 -- Yuanfudao has become the world's most valuable education technology unicorn at USD15.5 billion, according to the Chinese firm that recently completed its G1 and G2 financing rounds.

The online platform's valuation ballooned after it bagged USD2.2 billion in the two rounds, the Beijing-based company said in a statement today, without disclosing when the latest bout of fundraising ended.

The Series G1 round of funding was led by Tencent Holdings and participated by Hillhouse Capital, Boyu Capital, and IDG Capital. The following Series G2 was led by DST Global while Citic Private Equity, GIC, Temasek Holdings, and Trustbridge Partners were also involved.

Yuanfudao has doubled its valuation in a bit more than six months. In March, the firm closed its USD1 billion F round, led by Hillhouse Capital. Familiar names Boyu Capital and IDG Capital were also present. That boosted its valuation to USD7.8 billion.

The company will continue to invest in scientific and technological innovation, as well as new courses and services, it said after the latest financing.

Set up in 2012, Yuanfudao has education and research centers in more than 10 Chinese cities such as Wuhan, Xi'an, Zhengzhou, and Nanjing. It has more than 30,000 employees.
