I disagree that those are differences — in fact, what you’ve described as a ‘European’ startup is very much what most ‘US’ startups look like. There’s a few that have an idea and an opportunity to build on amazing growth and momentum, yes - in part because there is capital in the US that shares the appetite.
Yet outside of those few startups, most focus on customers and revenue. Our media certainly doesn’t explain it that way, nor do the big name venture bloggers because neither of them care about the startups that fall outside of the exciting high-growth 1%’ers. That’s not to say they don’t exist, it’s just to say that focusing on the 1% is what the media and VC models are built on so that’s how the US tells the story of startups and innovation.
