If you feel like the app TikTok came out of nowhere, you’re not wrong.

Since launching in early 2018, TikTok’s been covered by seemingly every major news publication and racked up millions of downloads globally.

Despite TikTok’s major early success, the app still feels like a bit of a mystery, especially to marketers. In fact, until recently, its parent company, ByteDance, hasn’t disclosed many metrics at all.

In TikTok’s first year, all we really knew was that an odd-ball video app was going viral, topping global app store charts, and gaining a huge fanbase from Gen-Z.

But now, shortly after TikTok’s first birthday, we know a lot more about it as sites like Digiday, AdWeek, and our own Marketing Blog regularly cover it.

Even if you still aren’t quite sure what TikTok is, you’ve probably seen a video meme on social media that was created and published in the app first. Here’s one for example of a TikTok post which went viral on Twitter:

When making decisions about your social strategy, you’re probably more interested in numbers than virality as proof of an app’s staying power.

As someone who’s gotten sucked into the app, blogged multiple times about it, hearted hundreds of posts, and even made a few embarrassingly mature videos of my own, I’m fairly certain that this platform will stick around for quite some time. But, luckily, with mounting data on TikTok, you don’t just have to take my word for it.

To help you make informed decisions about your strategy and whether TikTok is right for your brand, I’ve compiled a list of 28 interesting stats and facts to know before venturing on to the app.

Userbase, Downloads, and Growth

Within TikTok’s first year, it reportedly reached 500 million monthly active users. Wondering if this was just a fluke or a viral trend that will simmer down? Think again. According to TikTok and its company heads, the audience might be larger and more promising than we think.
