About Johannes

Ich bin John, Gründer von McGrinsey – einer Performance-Marketing-Agentur mit einem Faible für Daten, saubere Setups und smarte Skalierung. Seit zwei Jahrzehnten drehe ich an allen Hebeln im digitalen Marketing. Vom Suchanzeigen-Feintuning bis zum datengetriebenen Full-Funnel-Feuerwerk – wir liefern nicht nur Buzzwords, sondern echte Ergebnisse.

McGrinsey ist mein „Marketing-Labor“: Ein Team aus Spezialist:innen, das Strategie und Umsetzung nahtlos zusammenbringt. Zwei CMO-Gehirne mit über 20 Jahren Erfahrung, ein Dutzend Tools gleichzeitig im Einsatz und trotzdem nie den Menschen dahinter aus dem Blick – das ist unsere DNA. Wir kennen alle relevanten Kanäle (Google, Meta, LinkedIn, TikTok, Reddit, Native, SEO etc.) und denken nicht in Silos, sondern in Effizienz.

AI? Natürlich. Wir sind ganz vorne dabei – testen ständig neue Tools, automatisieren Prozesse und optimieren schneller, als du „Conversion Rate“ sagen kannst. Wir glauben an Transparenz, messbare Ergebnisse und daran, dass gutes Marketing auch Spaß machen darf.

Wir bauen keine PowerPoints fürs Archiv, sondern Wachstumspläne, die umgesetzt werden – schnell, durchdacht und immer mit Blick auf Impact. Wenn du also kein Marketing von der Stange suchst, sondern smarte Köpfe mit einem leichten Hang zur Marketing-Geekerei – let’s talk.
