About NIKKI
NIKKI is a family business and scale-up that started in the world of sports with one clear mission: to make financial health possible for sports clubs. Through social debt collection and smart administrative solutions, we now support nearly 400 associations and we’re bringing this model to the business world as well.

A word from our administration team
“At NIKKI, a strong organization runs on a strong administration.”
Our administration is the backbone of everything we do from processing payments and bookkeeping to reporting and supporting our clients. When the foundation is solid, everything else runs more smoothly.
As an Administrative Assistant, you bring structure, accuracy, and insight. You notice when something’s off, think in solutions, and help make processes smarter and more efficient.
What I personally love about this role is how involved you are in every aspect. You see the numbers come to life, spot connections, and support colleagues with the right information at the right moment. A well-organized administration not only creates internal peace of mind but also ensures our clients experience better service. And that’s what it’s all about in the end.
We’re looking for someone who looks beyond the numbers someone who thinks along, improves, and maybe one day takes the reins of the department.
Do you recognize yourself in this? Then I warmly invite you to read on.”
