The 6th largest Software-Provider in the World (SAP) is probably the most notable global german software firm. Deutsche Telekom, maybe.
As far as I am aware, there are some bigger gaming companies as well.
But this is, of course, a singular counterexample.
Germany has a large "Mittelstand", so medium sized companies and much stronger antitrust/cartell-laws. One could argue, that the lack of extremly large tech-companies is, for better or worse, by design.
Wirecard was a disaster for a multitude of reasons: The company itself [lost|stole|defrauded] a billion euros, their auditors (Ernst&Young, now "EY") failed to notice a billion euros of irregularities and lost their auditing license over the debacle. The german banking authorities failed in some capacity I cannot remember right now.
