Who We Are

We’re Ximedes — a team of 150+ developers, engineers, and product thinkers who build the technology that powers modern payments and public transport.

Since 1998, we’ve worked with leading banks, transport operators and public service providers across Europe to design, build and maintain platforms that move money, people, and ideas — securely, seamlessly, and at scale.

 

What We Do

We design and deliver complex technology systems in two industries where precision matters most: finance and mobility.

We build custom software platforms for onboarding, authentication, embedded payments, reconciliation, fraud prevention and more — always designed around compliance and security.

Here, we go beyond software — providing everything from backoffice platforms to validators, board computers and driver tools. 

In public mobility, we offer productised, composable systems like Account-Based Ticketing (ABT), Automated Fare Collection (AFC), Fleet Management and ITCS.

How We Work

We believe great software comes from teams who understand the problem domain, take full technical ownership, deliver with clarity and care.

Whether we’re writing code or deploying hardware, we work in high-velocity teams that stay accountable — not just to deliverables, but to outcomes.

Our solutions are built to integrate, scale and evolve. No vendor lock-in. No one-size-fits-all. Just pragmatic, elegant systems that work.

 

What We Value

Depth Over Hype

We go deep. Into the code, the standards, the compliance documents and the systems you already use.

Client and Team Happiness

Our two core KPIs: Happy clients. Happy colleagues. Everything else follows.

Composable Thinking

We build systems that can evolve — because no business stands still.

Smart People, Good Humans

We hire people who care. Who ask why. Who take pride in the details.

Offices & Reach

We’re based in Haarlem (HQ), with teams in Kleve, and Novi Sad — and we work with clients across the Netherlands, Germany, Nordics and beyond.

You’ll find our technology inside everything from European bank apps to public transport systems in major cities. And more often than not, you won’t even know it’s there — because great tech is invisible.
