Digital Marketing Consultancy

Marketing leadership that still gets its hands dirty.

I lead marketing like an interim CMO — and I'll run point on the operational work myself when a project needs it, including building the tools to do it.

Let's talk See my work ↓

Services

Interim & fractional marketing leadership.

I step in as your marketing leader — setting direction, running the team, and owning outcomes. When a project is strategically important enough to need it, I execute it myself: campaigns, launches, whatever the work requires, not just the plan for it.

Go-to-market strategy

Positioning, channels, messaging, and launch execution — built inside the engagement, not sold as a separate project.

Audits & implementation

A full-funnel audit and a prioritised, actionable roadmap — then the hands to actually implement it.

Skill highlight

DACH market fluency.

As a Dutch marketer based in Berlin, I know the region's buying culture firsthand: proof over promise, and longer sales cycles that earn deeper, more durable loyalty.

About

Senior marketing,
applied directly.

I'm Sebastiaan Rasterhoff — a marketing leader with over a decade of experience scaling digital marketing for B2B and B2C companies across Europe. I've led marketing teams, built demand generation engines from scratch, and helped companies navigate competitive markets with clarity and precision.

I work best with growing SMEs who need senior marketing thinking — but don't yet need a full-time CMO. I embed with your team, move fast, and make sure marketing connects directly to revenue.

Building with AI

I build with Claude Code.

What started as shipping my own projects with Claude Code — this website included, built and deployed end-to-end without a developer on payroll — has become something more formal: I'm a Claude Certified Developer, certified directly by Anthropic, with the certification issued via stuur.ai, the Anthropic-certified practice I operate. I'm not a developer by trade, but it means I can build and ship things myself when a project calls for it.
