Can you elaborate on the Europe is slower part?

Sure !

There is not a big entrepreneurship culture in general (at least in Spain & Southern France) so starting a startup, learning through others experience, next steps etc.. It's harder.

Also the social pressure is a big reason why entrepreneurship is hard. While in USA, failing and starting over is seen as something natural, in the various Spanish and French communities I have lived is seen as a disaster. Even more in some places is seen as an intent of showing everyone that you are smarter than them so you create your own product/service in stead of working in making better the existing ones. I think it's a cultural thing.

Thanks for this. It really didn't occur to me (as an American) that starting a startup somewhere else could be more difficult, but thinking about it more and trying to think of each of the steps required to even launch an MVP, I realize that these things have been made easy for Americans because of those startups who came before us.

My opinion (which may differ from the other user), USA is a big market with a lot of similarities (a common language). Europe is a set of different countries which can be very different and do not share the same language among other things like the laws, bureaucracy, culture, etc. And there are more startups in USA, the ecosystem is more mature. I think all this factors make USA more atractive to get traction

Thank you for this. That makes sense.

Completely agree with you
