Thanks for the input, and the whole „liability issue“ is something that I worry about. Being a sole-proprietor here (EU) means that you are liable with every personal asset, but it’s cheaper to set up and has not as much bureaucracy overhead.

I was also thinking about using something like Stripe Atlas to set up a US company, but I‘m not sure how expensive it is to run it (hire an tax attorney etc) over the year if it doesn’t generate any money.

I mean, I probably just have to try it out without worrying too much
