Few startups flourish anywhere. Or are you saying that all things being equal, a startup in europe has a lower chance of succeeding long term than in the us?

Any data to back this claim?

There's a distinct lack of mega-successes coming out of Europe.

From the article the difference doesn’t seem that huge:

Stockholm - 0.8 unicorns per 100,000

Silicon Valley - 1.4 unicorns per 100,000

Unicorn is just a threshold.

Of those in both regions that crossed it, how many went through the next, then the next order of magnitude?

In Silicon Valley terms a Unicorn is a company that can burn through 0.5-2.5 billion dollars a year for an unlimited number of years.

Silicon Valley has very few "unicorns" beyond those.

That's almost double in SV, that's pretty huge.

Given the differences in available capital and labour forces, reads more like stockholm is performing like an order of magnitude better.

I'd also be interested in seeing long term outcomes. I'd wager stockholms is stronger.

I don’t know if that’s a good success metric. Feel like a lot of smaller, but revenue sustainable startups would be better for economic health than one mega-Corp crushing competition

> Few startups flourish in Europe.

Well, after the US and China, the UK is the next biggest tech/startup environment worldwide. Startups obviously do flourish at least in parts of Europe, even relative to the rest of the rich world (Japan, Korea, Russia kinda, the Gulf states, even Australia/Canada).

Remove startups that burn through literally billions of dollars of unlimited VC money... and how many flourishing startups do you have left in the US?
