Can Web App built with Bubble be successfull?

I am interested if Bubble can be used for something more than POC.
What is the case?
I would like to create a web application which main goal would be to provide a html form to upload content which then could be used in mobile app.
I am going to mainly focus on the mobile application, the web app will also be important but I would rather prefer skipping steps of creating the app with something like Angular technology stack + some Backend.

From what I see - technically you can do almost anything with bubble, but are there some obstacles of making the Web App a successful product?
Please could you also point some successful ones?
Thanks in advance for clarification!

Kind Regards
