Release date
2020 - 2023

One of the most popular reality game shows on television in The Netherlands is public broadcaster AVROTROS’ yearly hit “Wie is de Mol?”. Currently an of average 2.5 million viewers watch the show. For the 2020, 2021, 2022 & 2023 seasons Elements developed a new backend platform and a new mobile app.  

In order to handle the extreme high peaks of traffic influx before, during and after broadcasts of the show, the backend platform is fully optimized and scalable. The project was directed by AVROTROS who worked in close collaboration with Elements, WeRiot and Praegus.


20% increase of app users

With the new features and expended social media functions we realized an 20% increase of app users in comparison to 2019. At the moment 1 out of 3 viewers uses the Wie is de Mol? app.

High scalability to a million users

To guarantee a functioning app during a Saturday evening episode the new backend is scalable to a million users at once. This way all the users can vote for their ‘mol’ and see real life statistics.

High scalability, performance management and flexibility

Over time, AVROTROS encountered a massive growth of user participation in the app and traffic on the platform. The growth and success of the app caused that the app was not always available for all users the past year.

Elements teamed up with partner WeRiot as they are specialists in data management and really love this kind of data challenge. With their flexible Catasta product, they were able to crack the code and deliver a scalable, flexible and high-performance solution.

This scalable Python backend comes with dashboards who show us real life statistics about the users of the app and the app performance. During the broadcasting of the show, we improved the app every week using the data from these dashboards.
