There’s a big question mark hanging over the future of TikTok right now, in the form of what exactly will happen to its U.S. business come September 20, when President Trump said he plans to shut down the Chinese-owned app over security concerns.

But in the meantime, it seems to be business as usual for the app.

Today, TikTok — which has 100 million users in the U.S. — announced a slate of marketing partners to help brands create and measure the impact of campaigns on the app, and a little later the company announced a new feature: Stitch, which lets users sample up to five seconds of video from another user in their own TikTok posts.

Stitch looks like it’s been in testing in some form since April, and the basic idea is to give users an easier way of “quoting” pieces of other videos in their work. For a platform where viral content, and specifically making videos based on popular TikTok memes makes up a huge part of activity and engagement on the site, it makes a lot of sense.

TikTok says that whether a video can be Stitched or not is up to the creator: you can change the default settings for all videos in your privacy settings, or you can toggle whether you want to use it or not each time you create a new video for the platform.

Those who chose to make a Stitch based on your video credit and link to your original video by default, which is a handy and nice way of making sure the original work or creator do not get too lost in the mix — unlike quite a lot of other viral content on social media.

Users who want to Stitch a video do so from the video itself. Hitting the sharing “send to” button, you will now get a Stitch option, which then takes you to an editing screen to create a clip of up to five seconds.

TikTok is keeping an eye on the money. For the marketing program, the company, owned by ByteDance in China, is kicking off with 20 partners that include companies for campaign management (e.g. Sprinklr and Bidalgo); for creative development (e.g. QuickFrame and Shuttlerock); branded effects around VR and AR (e.g. Bare Tree Media and Byte); and measurement (Kantar). The full list is below.

This is the latest expansion of TikTok for Business, the company’s advertising platform, which launched officially in June to bundle together TikTok’s existing marketing products alongside a new AR product it launched to rival Snapchat’s.

TikTok confirmed to us that this is a global initiative — that is, it’s set up to create marketing campaigns for wherever TikTok is available.

In the case of both the new Stitch feature, and in the new marketing program, I’m going to be honest: It feels a little like an alternate TikTok reality, like the kind you might see in a split-screen meme on the app itself.

Taking the marketing announcement, adding in marketing partners is very, very standard for a social media app that’s doubling down on making money through adtech based on its growing and engaged (and young) audience. Facebook (and the apps in its stable like Instagram) did it. Twitter did it. Snapchat did it.

And now TikTok is doing it. It speaks to the company’s ambition to expand its platform to work with the biggest brands and at scale, leveraging its strong audience growth to build advertising units to sell brands and products to them in innovative and sticky ways that are uniquely “TikTok.”

On the other side, of course, TikTok is having anything other than a standard growth trajectory right now.

It’s in the middle of a messy bidding process for ByteDance to sell TikTok’s U.S. assets (along, potentially, with others) to U.S. owners. The company has had to deal with the abrupt departure of its U.S. head. And now the situation seems to be spilling over into speculation over what might happen in other parts of the world, such as India. All of this means that it’s unclear what will happen to marketing relationships, and where advertisers and partners will be left if and when the app has to splinter.

Or indeed, how ad products and other IP like the new Stitch feature would be passed on in a potential sale. (Right now, reportedly, one of the sticking points for a deal has been the possibility that China might limit which algorithms, which form the basis of how TikTok works, would be passed on in a sale.)

“With the launch of TikTok For Business, we’re building new opportunities for marketers to be creative storytellers and meaningfully engage with the TikTok community,” Melissa Yang, head of Ecosystem Partnerships, TikTok, noted in the blog post. “We’re thrilled to collaborate with some of the most strategic and trusted leaders in the advertising industry and continue giving marketers access to more tools to successfully create, measure and optimize ad campaigns on TikTok. We can’t wait to collaborate with partners to bring a creative and joyful experience to our brand partners and the broader TikTok community.”

We asked TikTok if it can comment on how new features like these would be affected if and when the company does split up into regional operations, and it declined to comment specifically. “Unfortunately we’re not able to comment on speculation,” said a spokesperson. “In general we along with our partners are excited to kick off these partnerships and continue bringing more solutions to the marketing community.”
