N26, Klarna and Revolut are not tech companies. Neobanks are still banks. And Klarna is just modern store credit cards. These have been around for decades.
Adyen is very underrated, and Spotify is definitely tech.
Stripe should be on the list. DeepMind at one point.
Stripe was founded in California. It's an American business that focused exclusively on the American domestic market in their first years of operation. Many tech companies in the US are founded by immigrants from Europe and elsewhere. That the Collisons chose to start their business in the States is no coincidence.
Many EU start-ups choose to launch their product in the US first due to the 300+ million people market speaking only English, rather than bother with the tiny fragmented markets at home.
It's just much cheaper and easier for start-ups if you're developing a SW product to sell it in the US market first and only when you've made money there, slowly bring it in the EU.
Starting off SW products in the EU is suicide (unless you're targeting some niche in the local market that's safe from competitors from abroad because it ties into some local idiosyncrasies on language, culture and law).
