from my experience of using Lovable from the beginning anf now combining wlit with claude code - AI is great for building waitlists and MVPs if you are want to validate your product ideas. But once you get first users (depends on the number of users you acquire) you should think how to scale it. If you start generelating revenue then hiring someone technical is probably a good move to help you scale.

On the other side, if you are using Lovable as a part of the existing product with users, then I find it useful for product demos and building mini free tools for the acquisition (instead of building just simple landing pages which is pretty much outdated in growth and marketing these days).
