Who we are

Isatis, in full Isatis Software Solutions, was founded over thirty years ago by Jack van Poll and Jeroen Penninx. It grew from a local consultancy into a nearshore technology partner for Dutch and international companies, engineering based in Sarajevo.

From internal business tools to complex enterprise platforms: microservices, mobile apps, data platforms and AI solutions in healthcare, energy, government, manufacturing and education.

“Jack and I started Isatis with NCare, a project for Mosadex E-Health. The software checked medication when prescriptions were written and before medicines were given, including checks for overdosing, allergies and contraindications. We took the project to Bosnia, where our first three engineers worked on it. NCare was the start of our engineering organisation in Sarajevo.”

A culture to thrive in.

We’ve built a place where engineers have real ownership, ideas are heard early, and long careers are the norm, not the exception.

Quality 01

Quality

Pursue excellence.

We hold ourselves to high standards in everything we ship, from architecture decisions to the last line of code. Every change is reviewed by someone else before it goes out.

Respect 02

Respect

All employees, users and partners treated with respect.

Everyone can speak freely, contribute openly and feel valued, regardless of role, background or seniority.

Balance 03

Balance

Health above all else.

We watch workload and hours as closely as we watch delivery, because people who are worn out do not write good software.

Integrity 04

Integrity

Say it, do it.

We mean what we say and deliver what we promise, with clients, with partners and with each other. If a deadline is going to slip, you hear it from us first.

Stability 05

Stability

Consistent delivery, long-term commitment.

Three decades in business, built on consistent delivery and steady growth.

Passion 06

Passion

Good software comes from people who care about it. We hire for curiosity, and we give people room to keep learning.
