Honestly... not much in the traditional sense. you get a permanent tile in a collaborative mural being built by 100,000 strangers. Your photo lives there forever. The sooner you are the better number you have and more visibility. No utility, no rewards, no promises. It's closer to buying a brick in a community wall than buying a product. Either that means something to you or it doesn't
update: just added a $9.99 tier for photo + permanent external link on your tile. so now there's a tangible benefit for businesses and creators who want a permanent backlink. built it in about 20 minutes after someone else in the comments requested it. that's the honest answer to your question .. $1.99 is for people who want to be part of something. $9.99 is for people who want that plus a permanent link
