Growth Advisor · B2C & B2B SaaS

Marketing that actually moves the needle.

I built marketing at sevdesk from a small team to a 20+ function across Series B/C, and through a successful exit into private equity. Now I work with SaaS companies as an independent Growth Advisor.

Almost 10 years at sevdesk (130k+ customers). From Inbound Manager to VP Marketing.
Based in Offenburg, Germany. Bilingual DE / EN.

Point of View

Some of my beliefs about (SaaS) marketing

These are not best practices. They come from building and breaking things at scale.

01

Performance marketing alone does not build sustainable SaaS businesses. It rents attention, it does not own it.

02

AI should improve quality in marketing, not just productivity. A growth strategy built solely on productivity gains is not a strategy.

03

B2C tactics in B2B markets are underrated. The adoption curve of most B2B SaaS companies is unnecessarily slow.

04

Buyer-led economies will reduce the importance of traditional sales teams. Marketing will own more of the funnel.

05

Process problems matter more than people problems when scaling GTM. Most scaling failures are structural.

06

Behavioral economics explains more buyer behavior than logic does. Broad knowledge in this field will make you a better marketer.

Career

Experience

Nine years at one company is a choice. I wanted to see a product scale, not just join it mid-journey.
