About Johannes

Looking for a partner who doesn't just create concepts, but measurably leads your digital projects to success?


As a doctorial expert with many years of experience at the intersection of Digital Strategy, Marketing, and Product Management, I support startups and medium-sized companies in scaling their digital presence and achieving operational excellence. My approach combines analytical depth with a "hands-on" mentality.

How I help you:
  • Digital Marketing & Growth:Development and management of performance campaigns (Google Ads, Social Media), SEO strategies, and content marketing that sustainably increase your lead generation.
  • Product & Business Development:From the initial idea to market entry. I help define MVPs, optimize the user journey (UI/UX understanding available), and build efficient sales funnels.
  • Interim Management & Coaching:I fill competence gaps in your team, establish agile processes (Jira/Confluence), and support founders and teams as a strategic sparring partner.
  • Data Analysis & Automation:Using data for decision-making and implementing tools for process optimization (CRM, Analytics, Automation).
**

Why me?

Through my roles at startups and my academic career at the University of Mannheim, I know both worlds: the speed of the startup ecosystem and the methodical precision of research. I speak the language of developers, marketing teams, and stakeholders equally.

My focus projects:
  • Scaling digital business models
  • Optimizing marketing tech stacks
  • Interim roles in marketing management
  • Digital marketing projects (SEA, Google Ads, Meta)
  • Strategic consulting for digital transformation
Let's achieve your digital goals together. I look forward to your message and an initial exchange about your project!
