One swallow does not make a summer, all the major platforms are American and that's where Europe lags. I agree that Europe does have some great tech but they are all niche. Europe also have some great consumer tech products but they are all dependent on American platforms. For example some of the best games are French, Polish, Bulgarian, Ukrainian etc. but they all depend on Steam or Apple App Store and have to go by their rules and pay them a significant commission.

SAP sells B2B software, but most of their income is from consultancy and training.

That's a single company and I'd not call that great.
