Growth Leader · B2B SaaS

Marketing that actually moves the needle.

I built marketing at sevdesk from a small team to a 20+ function, through a Series B and a successful exit into private equity. Now I lead marketing at Sinpex, a Munich RegTech company.

10 years at sevdesk (150k+ customers). From Inbound Manager to VP Marketing.
Based in Offenburg, Germany. Bilingual DE / EN.

Point of View

Some of my beliefs about (SaaS) marketing today

Lessons from a decade in B2B SaaS, including the failures.

01

Performance marketing alone does not build sustainable SaaS businesses. It rents attention. The moment you stop paying, your pipeline disappears with it.

02

Most teams use AI to ship mediocre marketing faster. The real lever is quality. Productivity is the bonus, not the goal.

03

B2C tactics work in B2B more often than people admit. Most B2B SaaS adoption curves are slow because nobody on the team dares to test anything new.

04

AI is closing the information gap between buyers and vendors. Buyers research deeper before they ever talk to sales. Marketing continues to own more of the funnel.

05

Most GTM scaling failures are process failures. Already true in the hiring era, even more true with AI. Build the process before you scale it.

06

Most buyers decide emotionally and justify rationally afterwards. Teams who understand behavioral economics outperform teams who only optimize funnels.

Career

Experience

Ten years at sevdesk was a choice. I wanted to see a product scale from early stage to exit. At Sinpex, I’m building again.
