In 2022, new insurance legislation IFRS17 required official reporting for the first time. NN was ready with data modelling, calculation engines, accounting, data processing and we successfully delivered the numbers. However, analyzing such a large dataset proved to be a challenge. While each business unit managed its own figures, centralized analysis on a cloud platform with billions of records and 36 GB of data was difficult.

From the start of the project, Power BI was chosen as the reporting and analytics solution. But IFRS17 reporting goes far beyond dashboards and visualizations—it demands complex, fast and reliable reports. Our semantic model in Power BI worked initially but quickly became a bottleneck.

That’s when we brought in Pascal Betzel and Patrick Frenks. They restructured the model into clean and maintainable code. Hereby significantly improving performance and enabling scalable reporting. All of this while supporting test and production runs, resolving issues, transferring knowledge and advising teams internally. Microsoft also reviewed the model and concluded it required no further improvement—an impressive achievement given its size and complexity, making it one of the largest Power BI models in the Netherlands.

Pascal and Patrick also delivered solutions for ESG and tax reporting. They combine deep technical expertise with strong business acumen, proactively translating requirements without the constant need for a business analyst. They communicate clearly, professionally, and are a pleasure to work with. We tried to hire them internally, but they chose to continue building their own company and serving a wider range of clients.

Conclusion: No hesitation needed—quality and effectiveness are guaranteed, delivered by two outstanding professionals.
