Peter van den Bos

Peter van den Bos

Peter van den Bos is a Business Intelligence Consultant, speaker, and founder of Dutch BI Geek. For over a decade, he has helped organizations get a better grip on their data – making Power BI not just look good, but also run fast and make sense.

His sessions are a favorite among controllers, analysts, and BI professionals who want to understand what’s really going on under the hood.

His Dutch-language YouTube channel is a playground for anyone with a passion for Power BI – or anyone ready to embrace their inner data nerd.

Hafsa El Maizi

Hafsa El Maizi

Développeuse et facilitatrice passionnée depuis plus de 7 ans, je vois la tech comme un terrain d’apprentissage continu, où le code, les humains et les processus se rencontrent, et parfois s’entrechoquent, pour produire du sens.

Je m’intéresse aux pratiques Craft, DevOps et agiles, mais aussi à ce que l’on appelle trop souvent les “soft skills”. Pour moi, la performance d’une équipe repose autant sur la qualité du code que sur la clarté des intentions, la qualité des interactions et la sécurité psychologique.

Dans mes conférences, j’aime éclairer les angles morts, démystifier les bases et ouvrir des espaces de réflexion concrets, avec un goût assumé pour la nuance, la pédagogie et tout ce qui rend les pratiques techniques plus humaines.

Please note that Sessionize is not responsible for the accuracy or validity of the data provided by speakers.

Most Active Speakers 2025

Every year, we put together a list of the most active speakers. This list features the top 3% of speakers who have participated in events using Sessionize during the 2025.

The 3% is calculated from the pool of all speakers that have at least one accepted session in year 2025. We don't include inactive speakers or speakers that had no accepted sessions during the year. There are around 39,000 unique accepted speakers this year, the 3% is 1163. Not all of them have their speaker profiles set as public, and we respect that, so the list doesn't show all of them.

The calculation is based on the number of accepted events, that's the main criteria, but to get more refined results we also look at things like multiple sessions per event, sharing a session with a co-speaker and how big the event is. Number of submissions and declined sessions don't affect the list.

Please note that the count of events and sessions in this list does not represent the number of events and sessions from the year 2025. Instead, it shows the number of events and sessions featured on the speaker's public speaker profile; these numbers have nothing to do with the award itself.
