What this factsheet does not know
- How good the work is. Figures do not measure creativity, strategy or chemistry.
- How the client portfolio is spread. Concentration is not in the accounts.
- Freelancers and subcontractors are not in the FTE figures. An agency with 40 staff may in practice run with 70 people.
- The figures cover financial year 2025, filed on 13/07/2026. At a fast-moving agency reality today may differ.

People 13 people mapped
This team is built around client service: 4 of 13 are account & project. Within that core, Klantbeheer, Relatiebeheer and Projectleiding stand out. The titles skew top-heavy: lots of seniority, few juniors — you're mostly buying experience. Notably, no declared strategists in sight — this agency would rather make than philosophise.
Based on public profiles. Something wrong? Let us know.
Seniors or juniors?
Payroll cost per FTE is the best public proxy for a team's experience level. Higher is not automatically better, but it says something about who sits at the table.
- 42% women
- 58% men
Will your team stay?
Inflow and outflow from the social report. This series only counts people on the payroll: freelancers who invoice do not appear in it. A low figure therefore means two very different things, a stable permanent team or a small core with heavy outsourcing. A high figure usually points to short contracts. Compare only within the same type of agency.
