No and this is the whole appeal of UGC. Brands hire UGC creators for content they post on their own channels and ads, so your follower count is irrelevant and your ability to make good video is everything. You could have 12 followers and book steady work. What gets you hired is a portfolio that proves you can shoot well, talk to camera and sell a product. Build that instead of chasing a following, unless you also want influencer deals down the line.
Followers are not the product
Brands buy your content, not your audience. UGC is a content service.
Your portfolio sells you
Proof you can shoot and convert beats any follower count for UGC work.
Anyone can start
12 followers or 12k, the bar is the quality of your videos. That is freeing.
Followers help later
Want influencer deals too? Build an audience alongside. For UGC, optional.
