It's very simple to found a company in the US that has access to the entire 50 states and all of the investors therein, with a single/simple accounting to manage. And you don't have to live in the US to do it.

Europe/EU/EEA don't have a comparable setup. Found in one country, deal with workers in many, filings in all of the countries you're doing business, and more.

The new proposed EU Incorporation would go a long way to lowering the bar for getting started and accessing pools of funds between investors in different countries.

Has anyone thought about starting a "meta company" which attempts to provide a cross-national "compatibility layer" for doing business all across the EU?

For example, you could fill out a single set of paperwork, and then paperwork gets automatically generated for each individual country you want to do business in.

Yes but tech companies and startups are still highly concentrated in a handful of locations.

I don’t know how the difficulty compares to the EU, but US states require a bunch of per-state filings if you’re hiring employees that live there, in addition to the different tax regimes.
