UK, USA and Singapore are the popular choices for this. UK is simple and cheaper, Singapore is a bit more expensive. I don’t see a reason to go USA route unless you are seeking investment from there.
I’m using UK myself. It takes a few forms and half a day to get a working Wise/Stripe account.
Finally somebody who knows their stuff. I never understood why people preferred Estonian incorporation given that it's almost certainly more expensive and less convenient than the other options.
None of those countries are in the EU, which is important for my use case.
