About fiftyfivesixtysix 5566

Turning Potential into Performance. We help people and organisations move — from potential to performance, and from ideas to execution.

I’m Joost Jetten, founder of 5566: a platform for movement between people, performance and potential. We work at the intersection of sport, technology, learning and business, building and scaling initiatives with clubs, companies, educators and innovators across Europe. Our focus is where strategy meets practice — always aimed at real-world impact.

What defines our approach: - Connecting silos (sport ↔ business ↔ health ↔ education) - Translating vision into action - Building ecosystems, not standalone projects

How we help? - Strategic positioning & growth - Partnerships & scaling - Performance, learning & leadership development

For organisations, we bring clarity and momentum in times of growth or change. For individuals, we help uncover strengths, sharpen direction and activate networks.

We believe progress happens between layers — not within rigid frameworks.

That belief sits at the heart of 5566.
