I’m not so convinced by this. In the uk I think the big home grown successes are either serving the local market physically like supermarkets (though they are not very new as companies) or they will be relying on some difference in regulations from other anglophone countries. A business not in those categories needn’t be worse in general terms to lose to an American company, but the American competitor will have lots of advantages (cheaper fundraising, bigger market with more discretionary spending, more pro-business political environment, etc).
