Outcomes over output
I optimise for pipeline, revenue, and retention — not for activity dashboards.

Fractional CMO helping founders turn marketing into a growth engine
My Story
From in-house operator to Fractional CMO
Over the last 6+ years I've led marketing for SaaS, fintech, and marketplace startups across Europe and North America — building teams, launching products, and scaling acquisition from zero to thousands of customers.
I started in performance marketing, moved into growth and lifecycle, and eventually took ownership of full marketing functions as a Head of Growth and CMO. Today I plug in as a Fractional CMO so early-stage founders get senior leadership without the full-time cost.
I work hands-on: strategy, channels, analytics, hiring, and execution. No fluff, no vanity metrics — just outcomes that move revenue.

What I Value
How I work with founders
Data with judgment
Numbers point the way, but experience decides where to invest. I bring both.
Hands-on, not just advisory
I help build what I recommend — campaigns, processes, and the teams to run them.
Honest, founder-friendly
Direct feedback, transparent reporting, and no consultant theatre.
