Fractional CMO and Growth Lead for DACH companies
A new kind of growth partner.
Hi, I'm Simon Roser, a Marketing & Growth Lead for hire based in Berlin. My mission? To partner with ambitious companies and build their custom tailored growth systems that stay in-house, long after I'm gone.
How? I deliver hands-on support on foundations, data, and key digital channels, while bringing the strategic perspective of a fractional Marketing Lead. I've built my own brand (KNUS), and have scaled 100s of high tier Google Ads Accounts during my ~5 years at Google itself.
My jam? Cutting through the noise, aligning the chaos, and empowering your team with the data & principles needed to keep that growth momentum rolling. Outcomes first. Always.
Let's grow?
Their potential for growth is my motivation.

Building marketing foundations that last. I help pre-Series B companies create stellar in-house marketing teams that thrive long after I'm gone by transferring expertise, not just executing campaigns.
