Data people from Warsaw.
Microsoft people since 2001.

Onex Group is a Microsoft Solutions Partner and Fabric Featured Partner specialising in data and AI. We help mid-market and corporate organisations organise their data with Microsoft Fabric, turn it into insight with Power BI and data science, and keep it secure and well governed with Microsoft Purview, so your people and your AI can make better decisions.

// Microsoft Solutions Partner

We believe every organisation should be able to trust its numbers and act on them. As a Microsoft Solutions Partner and Fabric Featured Partner, we build the data foundations that make that possible: a single source of truth, reporting that runs itself, and data that is ready for Copilot and AI agents. After all, AI is only as good as the data behind it.

Our values

Our values shape how we work with every client, from the first conversation to long after go-live. They are what you can expect from us, and what our team holds itself to every day.

Accountability

We take ownership of the outcome, not just the task. We are clear from the outset about what we will deliver and what it will take, flag difficulties early and treat the success of your project as our own.

Proactivity

We don't wait to be asked. If we spot a better way of working, a risk on the horizon or an opportunity hidden in your data, we tell you, and we come with a proposed solution.

Professionalism

Everything starts with your business needs. We prepare thoroughly, base our recommendations on hard data rather than opinion and build solutions that scale. If something goes wrong, we own it, fix it and learn from it.

Collaboration

We work as an extension of your team, towards one shared goal. We share our knowledge openly, give honest and constructive feedback, and are not afraid to challenge the status quo when it stands in the way of results.

Flexibility

Priorities shift and technology moves fast. We adapt quickly to new requirements and are ready to go beyond the original scope when your project calls for it, without losing sight of the goal.

New looks, one X.

From a teenager’s website to a Solutions Partner, the mark grew with the company. The X has been in it since 2008. Today it is four arrows pointing to the centre.

Twenty-five years with Microsoft

It all began in 2001 with a simple website dedicated to Windows XP. What started as a hobby project quickly grew into CentrumXP, one of Poland’s most popular technology portals focused on Microsoft technologies. In 2005, that passion evolved into a professional business, and Onex Group was born.
