Fractional executive leadership

Fractional Executive & Transformation Leader

Sometimes a company needs more than a sprint. As a fractional executive I embed directly into your leadership team — the depth of a seasoned C-level with the flexibility of an independent.

With previous executive roles at KPN and Level(3) Communications, 8 years running a telecoms consultancy serving international clients, and 9 years as founder and CEO of Dimanex — the experience spans both sides: corporate execution at scale and entrepreneurial building from zero.

  • Interim CCO / CGO / Chief of Staff for Series A–C scale-ups
  • Innovation strategy and go-to-market for corporates in transformation
  • Board advisory and investor-readiness preparation
  • Management team assessment, coaching and stakeholder alignment
  • Market entry strategy for EU and international expansion
