They also didn't come first. Vine was a very popular platform that seemingly shut down out of the blue (at the height of it's popularity). There was no real replacement for a long time after that. Tiktok first started out as Musically, allowing people to create mainly dance and lipsync videos. Only later they rebranded to Tiktok and pivoted to general purpose video content.

The point is, even tiktok didn't just get right and had to pivot and maybe that is key. So to the op I would say: try your idea but just be very very spontaneous and flexible to change it quickly if it doesn't work.

yeah exactly, no amounts of user research would lead to "people want a platform like tiktok"

With the possible exception of Vine's 200 million users.
