Are there firms (LLCs or sole proprietorships) for individual developers?

Question

Android

Tell me, please, are there companies or something similar that a developer can get a job in order to work on their own projects?
As I imagine it: a developer creates good applications and wants to sell them, for example, on Google Play, honestly, with payment of taxes, but cannot or does not want to open an individual entrepreneur / LLC on his own. Then it would be possible to get a job in a company, from income from Google to pay her a percentage. And this company would already be independently dealing with legal issues, paying taxes, etc.

Answer 1

I think the existence of such a company is not commercially justified. Opening and maintaining your IP purely for development is a trifling matter. Or, contact the publisher. When Google Play did not allow selling applications in all countries, such a business flourished quite well, yes ...
