++Our story
Built on experience, not on an idea.
tre plus connects Dutch product teams with developers from Kosovo. Through Developer as a Service and Team as a Service, we show that a great team doesn't need the same building. Just the same mindset.

++Meet the team

++Our journey
From experience to our own company.
- Late 2022
First working day in Kosovo
In the role I held at the time, I start working on building a development organisation in Kosovo.
- 2022-2025
From a first team to almost 70 FTE
I help the organisation grow towards almost 70 people. Along the way I learn what selection, onboarding, local support and client integration really take.
- The lessons
What works and what doesn't
Developers have to become part of the client's team. Clients have to make the choice themselves. And technical direction has to stay with the client.
- July 2025
tre plus starts
I start tre plus to put those lessons into a smaller, more personal model for product companies in the Netherlands and Belgium.
- Today
Our own office in Pristina
Since April 2026 we recruit and support developers from our own office. Clients talk to me directly and lead the developers inside their own product team.
++Our journey
From experience to our own company.
tre plus isn't a startup without history. It comes from years of working with developers from Kosovo, with everything that involves.

++What drives us
Our core values.
Ownership
We don't just deliver code. We think along and take responsibility for the result.
Transparency
Open communication, honest timelines, no surprises later on.
Continuity
We build long-term teams, not project-based setups with changing faces.
Quality
Senior developers only. We don't cut corners on talent.
Ownership, not a ticket queue
Our people think along with your product, not just the next task on the list.
Flexible capacity
A fixed monthly fee, no employer overhead. The collaboration should be the reason to stay, not the contract.
We handle continuity
Someone drops out? We arrange a replacement with comparable experience.
