China’s Bytedance is buying in a deal worth $800M-$1B, the lip-syncing app popular with teens and young people, has been sold to Chinese social media giant Toutiao, according to an announcement made today.

The deal is undisclosed but sources tell TechCrunch that Bytedance, the company behind China’s top news aggregator service Toutiao, will pay between $800 million and $1 billion to buy, which claims 60 million users most of whom are based in the U.S.

Three-year-old was previously valued at $500 million when it raised its most recent round of funding in 2016. The startup said it will continue to run as an independent business within Bytedance, taking advantage of the distribution and tech that its new parent offers.

Bytedance itself has been on a tear over the past two years thanks primarily to Toutiao, which claims 120 million monthly users. The firm is reported to be raising as much as $2 billion in new funding at a valuation of $20 billion, and it has expanded into other types of mobile content through acquisitions such as video app Flipagram.

Toutiao has become well known for its extensive use of artificial intelligence to help build a tailored newsfeed for its user base, and in an announcement today the companies said that this tech will be used to develop’s reach in terms of users and creators in China, Korea, Japan, and Southeast Asia. These are regions where the company hasn’t really made a mark to date, despite the fact that its founders are Chinese and its head office is in Shanghai, but Bytedance has a growing presence in them.

In that sense, there’s plenty of synergy to the deal — which gives insight into how keen Bytedance is to expand overseas, having already found huge success in the Chinese market.

At a time when investors have cooled on social media, will be viewed as a rare success story. There’s a commonly held view that it’s almost impossible to stand out amongst a crowded market which includes Facebook, Snapchat and Twitter. In that way, Bytedance is similar since it has emerged to become a super company in China, where Baidu, Alibaba and Tencent have traditionally dominated as the big three.

In’s case, it latched onto the tween demographic and quickly developed cult fanfare. From music videos to live streaming, the platform built a full-fledged social network comprised of four apps, with some users becoming stars.

And it’s not just user-generated content. Viacom, NBCU and Hearst have been developing short-form interactive videos.

In the business community,’s success was initially under the radar. When we broke the story of its funding round 18 months ago, the startup name hardly rang a bell for most adults in Silicon Valley. The Shanghai-based company had both local and Silicon Valley investors. Greylock Partners, GGV Capital, DCM and Qiming all saw’s promise.

Despite that promise, there is controversy. has defended the way that it works with its young user base — with many not even in their teens — after concerns about how it handles data and permissions.
