I have to say I'm not very surprised by any of these companies except maybe Klarna. Fast-delivery companies which probably never can be profitable in EU and Kry who's farming government subsidies.
Ukraine war is probably hitting Europe much harder than US or far east.
But the second point is absolutely true. The cost of living crisis in Europe is far more acute due to the effect on natural gas prices and some other items (cooking oil, etc.). The increase in interest rates has also been much greater.
That leads to consumers cutting discretionary spending at a much faster rate, killing off loads of "nice-to-have" startups dependent on that like grocery delivery, cheap credit, etc.
And as the Americans say - "we ain't seen nothing yet"
US got Tesla. Yet who is threatening Euro too-big-to-fail car manufacturing behemoths?
Yet manufacturing is still moving away to Asia and energy issues are ever present with many anti-nuclear advocates with questionable funding. And instead of fixing actual societal issues some twats want to play Euro Empire Building out of EU. But same twats can't even defend an ally in a bloody war.
