TikTok CEO will face from Congress today over a possible ban
On Thursday, TikTok's CEO, Shou Zi Chew, will be opening a lion's mouth and placing his own head into it.
He's giving testimony in the US Congress for the first time, a scary thing to do.
And at stake is the future of the phenomenally popular video-sharing app in the US.
"I think that there is a real risk that if this hearing doesn't go well… that could have a massive impact on the future of TikTok," said Chris Stokel-Walker, author of TikTok Boom.
Mr Chew is likely to face a barrage of questions on TikTok's relationship with China, what data it collects, and what it does with it.
He'll also be quizzed on why several journalists were spied on by ByteDance employees - something TikTok has already admitted.
Mr Chew will say user data is safe - away from the reach of the Chinese government.
He knows politicians from all sides want to see the platform either sold - or outright banned in the US.
"He's going into the lion's den," said Mr Stokel-Walker.
Mr Chew is going to need to give the performance of a lifetime. And already, close observers have seen a change of tactic from the Singaporean.
TikTok's boss, who has had a range of senior positions in the world of finance, generally sports a suit jacket and tie.
But on Tuesday, he posted a TikTok with a very different look.
Instead of a suit, he was wearing a white T-shirt and hoodie - the uniform of the nonchalant tech founder.
The 40-year-old was suddenly speaking like a teenager too - talking of being "super excited".
"I think he's trying to give off a sort of the casual tech bro," said Caitlin Chin from the Center for Strategic and International Studies, a bipartisan think tank.
"He's actually been starting to gain a bit more of a public profile, especially leading up to this hearing."
The Singaporean has generally kept a low profile since taking over at TikTok in 2021.
The big problem TikTok has in the US and Europe is that it is owned by a Chinese company, ByteDance.
And in China, there are specific laws that require companies to hand over information to the Chinese Communist Party if requested.
