Employee Testimonial: Sebastian ten Cate, Product Development Manager, NL

“I didn’t follow a traditional path, but I was given the chance to grow, and that made all the difference.”

What’s special at Kolo is how growth happens: not through a rigid path, but by being trusted to take things on and learn as you go. I started as a developer, and in just a few years, I’ve taken on leading product development, co-piloting our new website, managing a full software transition, and helping bring our new brand to life. None of that came from ticking off a checklist, it came from people seeing potential and giving me the space to prove it.

The culture is fast-paced and focused, but grounded in mutual respect. People care about outcomes and quality, but also about each other. There’s a great balance between high standards and being approachable, which makes collaboration across teams and countries both efficient and enjoyable.

What drives success here is a proactive mindset. Those who thrive are solution-oriented, not afraid to ask questions or challenge the status quo, and keen to build, not just execute. It’s an environment where your impact grows with your initiative.

The thing I’m most proud if is simply the role I hold today. It didn’t come from a traditional path, it came from stepping up, being supported, and growing into the work. I’m now in a position where I can shape how we operate, connect technical and people-focused efforts, and work with a team that’s professional, diverse, and highly committed.

Looking ahead, I see my role as helping Kolo scale with clarity, streamlining the way we work across functions, creating better systems, and strengthening collaboration. Helping great people work better together is what really excites me.

If you’re someone who’s eager to contribute, learn fast, and make a difference across borders, Kolo is a great place to do it.
