We did not start as an agency.
We started as builders.

For over 20 years, the same team has been shipping software that organizations depend on. That track record is what you get when you work with us.

Our story

Same team. New chapter.

The core of Dextrasoft is a team that spent over 15 years building one of the Netherlands' leading procurement platforms — Negometrix. When it was acquired by Mercell, we did not scatter. We started Dextrasoft.

2006
Team comes together around Negometrix
A small group of developers in Sofia begins building an e-procurement platform for the Dutch market.
2009
NX3 launches
A full platform rebuild. Negometrix grows to serve hundreds of Dutch public buyers.
2017
NX4 — the enterprise version
A second full rebuild. The platform now handles billions in public procurement contracts annually.
2022
Negometrix acquired by Mercell
One of Europe's leading procurement companies acquires Negometrix. The team stays together.
Today
Dextrasoft — a new chapter
Same people, same standards. Now building for companies across the Netherlands and beyond.
Why us

What makes us different.

01
We have built at enterprise scale before
Negometrix was used by thousands of organizations and processed billions in contracts. That is not agency experience — that is product experience. We know what breaks at scale because we have been there.
02
Permanent employees, not contractors
Every developer who works on your project is a permanent Dextrasoft employee. Not placed by an agency, not on a short contract. The team that starts your project finishes it.
03
Small teams, full accountability
We work in teams of 3 to 6. Every person on the team knows your project in detail. No handoffs, no knowledge gaps, no junior developers hidden behind a senior face.
04
Long-term by default
Most of our clients have worked with us for years. We do not deliver and disappear. We stay involved after launch, keep improving the product and treat your software as our own.
Our team

The people behind
the work.

25 permanent employees. Developers, designers, business analysts, QA engineers and product owners. Most of them have been here for over a decade.
