Benni De Jagere

Benni De Jagere

Benni is a Principal Program Manager in the Fabric Customer Advisory Team (Fabric CAT) at Microsoft. Aspiring to be top notch in his field, through continuous personal development, on both technical and soft skills. He strives for maximum results in his tasks using team play, communication, thinking outside of the box, and (endless) motivation. Benni is always ready to tackle the unknown, or pick up fresh ideas to broaden his range. Building on past experiences, he continuously tries to find new, more efficient ways of obtaining results, and improving the process along the way.

Loving (almost) every day of it, he’s fascinated by the value of data, sometimes flabbergasted by the lack of awareness, and intrigued by the endless possibilities whilst discovering new ways of looking at data. He thrives on unfolding new insights for customers whilst using an open and transparent communication.

On a daily basis he turns (large amounts of) coffee into insights for customers, and references witty British comedy, lame dad jokes, and obscure facts way too often. Overly enthusiastic about anything data related, he’s trying hard to keep up with all things new and shiny.

When not working, blogging or reading, you’ll likely find him out and about being his weird self. Rumour has it that he’s also involved with a ragtag band of data enthusiasts, enjoying themselves whilst organising cool community things.
They go by the name of .. dataMinds!

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.
