Try TikTok. You can promote your post to get followers, it doesn't cost much. And you'll need to do that at first to gain followers unless your posts capture the imagination.
Of course there's no guarantee TikTok will show your content to your followers - it's just easier to get numbers, and hopefully some interested followers. I have 400+ followers, but new posts don't get anywhere near that many views. TikTok never shows me their videos for some of the people I follow. I have to specifically go to their profiles and view the videos (that happens when you have diverse interests - they tend to show you more of the same).
