Skills

Als Unternehmer und passionierter Problem­löser blühe ich auf, wenn es darum geht, technische Herausforderungen, Designprobleme und Business Probleme anzugehen. Ich genieße es, tief in das Verständnis des Problems einzutauchen - die schmerzhaften Konsequenzen zu erkunden und die Wurzel des Problems zu identifizieren.

Diese Herangehensweise ist sowohl ein Segen als auch ein Fluch: Ein Segen für Kollegen und Partner, die kritisches Denken schätzen und die Wahrheit suchen, aber ein Fluch für diejenigen, die intellektuell faul sind und nicht bereit sind, die extra Meile zu gehen.

In den letzten zehn Jahren hat sich meine Denkweise durch die Zusammenarbeit mit verschiedenen Startups und der Gründung von drei Unternehmen weiterentwickelt. Immer wieder haben diese Erfahrungen die gleiche unschätzbare Lektion bestätigt:

Liebe das Problem, nicht die Lösung!
 

Kunden haben mich für folgende Anwendungsfälle/Probleme beauftragt:
  • Produktstrategie: Spezifizieren des Kernproblems, des Zielkunden und deren Zahlungsbereitschaft.
  • Produktentwicklung: Entwicklung eines Produkts von 0 bis hin zur erfolgreichen Markteinführung.
  • Kundeneinblicke: Den Grund verstehen, WARUM deine Kunden dein Produkt gekauft haben, da die Gründe höchstwahrscheinlich von deinen Annahmen abweichen.
