i-spark supports Sdu’s data team with online data expertise

A long-term partnership focused on smart data solutions, user insight, and continuous co-creation.

Client snapshot

Sdu is a major Dutch publisher offering online products, training, and legal content tailored for professionals who actively apply legislation and regulations in their daily work, such as lawyers, legal consultants, and compliance experts. Their platforms, including ndfr.nl and opmaat.sdu.nl, help professionals perform their work faster, smarter, and more accurately. Subscription-based online services, where ease of use directly drives value and user retention.

Why Sdu partnered with i-spark?

To keep improving product usability and effectiveness, Sdu needed insights into how users interact with its tools. i-spark was brought in as an external Data Team, working closely with Sdu’s Marketing Intelligence Team to capture, organise, and analyse online usage data

What was the challenge?

How do you measure ease of use and improve it?

For a content-rich platform like Sdu’s, user-friendliness is essential. If lawyers and legal professionals can’t navigate quickly or find what they need, they churn.

But with multiple platforms, fragmented data, and evolving privacy requirements, it became difficult to:

Collect consistent, compliant web statistics
Track user engagement across different products
Attribute conversions to specific marketing efforts
Spot early signals of churn

Sdu needed a unified, privacy-proof data solution and a flexible partner to help drive it forward.

What was our solution?

i-spark filled the gap by acting as Sdu’s external Data Team, working side-by-side with internal experts to capture meaningful, up-to-date insights.

Automated data delivery pipelines

We set up custom pipelines to ensure Sdu’s reporting is always fed with the right data, on time.

Web + Transaction data integration

Combined behavioural and transactional data in a central warehouse—fully compliant with Sdu’s privacy policies.

Google Tag Manager standardisation

Implemented uniform data collection across all platforms using GTM.

Custom web analytics with Snowplow

Implemented Snowplow for advanced tracking and developed a custom data model tailored to Sdu’s products.

Consent Management with Liveramp

Helped implement a Consent Management Platform and ensured consents were properly respected in tracking setups.

Advanced analyses

Conducted in-depth analyses such as:

- Conversion Attribution to map marketing impact
- Churn Analysis to identify causes of subscription drop-off

The impact? Turning insights into product improvements and business growth

Sdu gained insights into product usability with a privacy-first approach, strengthening an agile, long-term partnership that continues to deliver value.

"I have been working pleasantly with i-spark for quite some time. Their honest, result-oriented and no-nonsense approach gives me a lot of confidence and their specialist knowledge in the field of data and data analysis helps to solve complex issues. The combination of thinking along and practical application unburdens me and is exactly what I am looking for in a partner. The people at i-spark feel a bit like an extension of our organization."
