What websites allow you to look up the revenue of very small companies?

I apply for a lot of jobs with entrepreneurs and I often find out their ventures aren’t doing anything. Unfortunately, I have to put in a lot of effort to figure this out. Is there a way to just type the small company’s name into a website and find out how much they are making?
