By 2012, growth exploded higher by over 300%. Sohu.com purchased shares back from Jack Ma, and by 2013, sought out new partnerships. It took Wang Xiaochuan one meeting with Pony Ma, CEO of Tencent, to convince him of the benefits of the merger. In exchange, the #4 search engine in china, SoSo.com, merged with Sogou and an equity investment of $448M was made. By 2014, Sogou became the default search engine for QQ.com, the #2 website in China. Also in 2014, Sogou became the only search engine to be able to search WeChat public accounts. By early 2015, Sogou became profitable.
