Your marketing needs a leader before your budget can carry a full-time one
That gap usually shows up during a new growth phase. Sound familiar?
Sales asks for more pipeline, and marketing answers with more activity.
Your team is good, but nobody sets the direction or says no.
The board wants a marketing story you can defend with numbers.
You are preparing for a round, or an exit, and positioning still feels loose.
Choose your fraction
Three ways to work together. Each one can scale up or down as your company changes.
1/5
Operating Advisor
One day a week to coach your marketing lead, sharpen the plan and keep the team honest about results.
For teams with a capable lead who needs a senior sparring partner.
2/5
Fractional CMO
Two days a week as your head of marketing. I own the strategy, lead the team and report to the board.
For scale-ups between Series A and C without a marketing leader.
3/5
Interim CMO
Three days a week through a gap, a reorganisation or an exit, then a clean handover to your next hire.
For moments that need more hands on deck, for a set period.
Delivering from week one
No ramp-up phase. I start on live work in the first days, and the plan grows out of what ships.
Day 1
In the work
Access to your data, pipeline and team. I join the next sales and marketing meeting and pick the first problem to fix.
Week 1
First fix live
One change that moves pipeline ships: a leaky funnel step, a weak page, a stalled campaign.
Month 1
Plan on one page
Positioning, priorities and a board-ready view of the numbers, built from what the first fixes taught us.
Quarter 1
Built to last
Channels, team and reporting in place, and a clear call on whether to keep, grow or reduce my days.

Hi, I’m Rolf
I started doing web and marketing work at 14. Since then I have led marketing at B2B software companies through four exits, the latest as CMO.
I have European and Asian roots, lived in Singapore and Jakarta, studied international communication, and now work from the Netherlands with scale-ups across Europe. Next to client work I advise founders, mentor marketing leaders and speak about growth.
Off stage
Father of two, friend of founders.
I live in the Netherlands with my family, and we travel whenever we can. The founders and operators I work with tend to become friends and recurring collaborators.
