Turning marketing chaos into clarity, accountability and growth.
Helping founders and leadership teams turn fragmented marketing into scalable systems, aligned teams and measurable growth.
I work as a Fractional CMO and strategic marketing advisor for B2B SaaS, e-commerce and growth-stage companies across DACH and the Nordics, building the strategy, structure and performance foundations needed for sustainable growth.
Marketing Should Create Clarity, Not Complexity.
Many companies invest heavily in marketing but still struggle with inconsistent results. Campaigns are running, content is being published, agencies are delivering reports, yet growth stays unpredictable. What looks like activity is often closer to chaos: teams work in silos, priorities shift constantly, and no one has a complete view of what actually drives revenue.
This is where strategic marketing leadership becomes critical. I help companies align strategy, execution, technology and teams into a marketing function that supports long-term business growth.
Does this sound familiar?
I help CEOs spend less time managing marketing and more time running their business. These are the patterns I see most often in companies that are ready for a different approach.
Your agency reports activities, but not business impact.
Marketing, sales and leadership are pulling in different directions.
Nobody can clearly explain what is working and what is not.
You are still the person connecting teams, freelancers and tools.
Marketing feels busy, but growth feels inconsistent.
Behind every one of these patterns is the same structural gap: no clear ownership, no shared direction, no single person accountable for the outcome.

Senior Strategy.
Hands-On Execution.
I am Sonja Greye, a Fractional CMO and marketing strategist based in Sweden, working with B2B SaaS, e-commerce and growth-stage companies across DACH and the Nordics.
Most companies face a trade-off. Specialist agencies and freelancers execute a single channel well, but work in silos and lose sight of the bigger picture. Strategic consultants bring direction, but often lack the hands-on experience to make it work in practice.
I combine both: senior marketing strategy and practical execution across paid, organic and lifecycle marketing, from full-funnel planning down to the campaign level. That lets me set the direction and orchestrate the specialists, agencies and tools that deliver it.
Before my marketing career I served as an officer in the German Armed Forces, leading teams in high-responsibility environments. That foundation still shapes how I build structure, accountability and clarity into marketing organizations today.
More about my background →How I Help Companies Grow
Every one of these is an application of the same approach to marketing as a system. See how I think about it →
Fractional CMO
Most growth-stage companies need senior marketing leadership but cannot justify a full-time CMO. I provide the strategic direction, accountability and execution oversight of a CMO, embedded in your team, at a fraction of the salary and overhead. I have built marketing functions from the ground up at multiple companies. That hands-on experience is what I bring to yours.
