Jan Sonck @ DISUMMIT 2017: “Mobile network data, a lever for augmented contextual insights”

DiS17_Speaker_09:00_Jan Sonck

Jan Sonck is the Head of Enterprise Innovation at Proximus, the largest Belgian telecommunications company, where he has also been in charge of Indirect and Multi-Channel Solutions, Marketing and Business Development. Jan is also an experienced marathon runner.

About Jan and how mobile data is being used today

Being a such a large telecommunication company as Proximus gives place to a large set of opportunities to use data, and that is what Jan came to share with us.

The fact of having an increasing  number of people using mobile devices, sketching their digital fingerprint, triggered the collaboration of academia with the telecomm companies to perform joint research offering an overview of the qualitative and quantitative elements the user is considering in his daily life.

Following academia, the collaboration has been extended to other players, such as governmental institutions (at all levels: from municipal to European) and management consulting firms.

These synergies have led to an increasing accuracy on crowd analytics displaying trajectories and new types of visualization (in 2D and 3D). This also involves fusing multiple data sources,  and promoting the importance of open data. The result of this is using mobile data for prediction on a real time basis in different contexts, ranging from large-scale events (for instance, music festivals), air quality, and mobility, among many others.

In a nutshell, collaboration should keep on permeating all sectors, keeping citizens in the loop with the way their data is being used.

A takeaway from Jan’s presentation

“The increasing complexity of data requires to have a deeper sense of collaboration”


We look forward to meet Jan soon so he can tell us how collaboration towards mobile data is evolving!

Job – Proximus – DataMiner


We have just been requested by our friends from Proximus to share this great career opportunity.


Business Intelligence Specialist – “Dataminer”


Within the Customer & Market Intelligence department  belonging to the Proximus Group Strategy & Transformation, you will be part of the team  in charge of statistical analysis (predictive modelling – datamining) and advanced customer analysis.

You will answer business requests and give advice to internal customers based on advanced data analytics. You will translate those business requests into data requirements and extract, mainly by using SQl, the needed data from the Proximus Data Warehouse and other sources if needed. You will use existing datamarts or structure all relevant data in data marts specifically designed as input for your ad hoc analyses and statistical models. Your analyses can be descriptive (e.g. customer profiling and segmentation) or predictive (e.g. churn prediction models).

You will transform the data into insights to come up with recommendations to influence strategic decisions or tactical choices. You will present your conclusions and discuss them with multi-functional project teams.

You will interact mainly with colleagues from Marketing & Product Management, Data warehouse and other CMI departments.


  • You love researching, measuring, analysing and quantifying things. You spontaneously look for patterns in data. You like precision but you are not afraid to make an educated guess.
  • You are curious, eager to learn and result driven.
  • You are good at visualizing data and making impactful presentations. You can easily express your ideas in writing or in meetings.
  • You are a team player and you stay cool under pressure in peak times.
  • You allocate your time efficiently and can manage several projects in parallel

Knowledge & experience:

  • You have a good knowledge of datamining and statistical modelling techniques.
  • You have a good  knowledge of SQL (Oracle/Teradata), BI tools, databases and Data warehouses.
  • You are able to switch between your business skills and technical skills : you start from the business question, you define the solution, you translate in scripting language (SQL) and statistical analysis and finally you present the result in a marketing understandable language
  • You have a Master degree in a quantitative oriented discipline
  • You have some years of work experience in a complex and data-driven environment.
  • You are fluent in English and Dutch or French.
