07.08.2025 - 04:17 Uhr Berlin. Seit drei Jahren boomt das Geschäft mit Künstlicher Intelligenz (KI) weltweit. Tech-Firmen konkurrieren um immer größere und leistungsstärkere Grundlagenmodelle. Doch die Zweifel an den Anwendungen nehmen zu : Je komplexer die Aufgaben für KI-Modelle werden, desto eher kommen sie an ihre Grenzen. Was also bleibt, wenn sich der Hype legt? In Europa wächst eine KI-Szene heran, die Antworten auf diese Frage sucht. Start-ups mit tiefem technischem Verständnis und klugen Ideen, die Mehrwert schaffen und Pionierarbeit leisten, zeigen: Entscheidend ist nicht die Teamgröße oder das Finanzierungsvolumen, sondern die Geschäftsidee. Für die Serie „KI-Start-ups jenseits des Hypes“ hat sich das Handelsblatt in der europäischen Szene umgesehen und nach technologischen Innovationen gesucht. Die acht porträtierten Firmen stehen für zentrale Trends der KI-Branche und prägen sie entscheidend mit. Den Beginn macht Langfuse – ein Berliner Unternehmen, das von Entwicklern und Investoren so häufig genannt wird wie kaum ein anderes, wenn es um die spannendsten KI-Start-ups geht. Langfuse hat ein Tool entwickelt, das KI-Modelle und -Agenten testet, überwacht und optimiert.
