Olivier Van Steenlandt

Olivier Van Steenlandt

Olivier Van Steenlandt is a Business Intelligence Professional who spent most of his early career assisting retail companies to get more value of their data using the Microsoft BI Stack (SSIS, SSAS, SSRS, Power BI).

As his first experience in the field (in Business Intelligence), Olivier worked as a Big Data Analyst using tools such as Hadoop and Spark.

In 2015 the focus changed to traditional data warehousing & reporting using SSIS, SSRS & MicroStrategy. A bit later, around June 2019, the opportunity arose to fill the position of BI Teamlead. In this function he was able to set up a hybrid BI Team (team members in Belgium and Belarus).

Early 2020, Olivier joined the dataMinds crew as a core member, assisting to organise several events.

Around April 2021, Olivier started a new position as BI Teamlead in another Retail Company to support business growth. Besides the challenge to help the BI Team grow and deliver projects on time, he started to use SSAS & Power BI.

In April 2025, Olivier stepped away from internal positions and became an independent consultant.

When Olivier is not working there is a high chance that you find him on a football field, studying (BI Related), playing music (Saxophone / Piano) or cooking.

As Principal AI Product Manager at Microsoft, my focus is on helping customers reimagine what’s possible with Cloud, AI, and virtualization technologies, as we move “From a computer on every desk in every home, to a PC in the Cloud on any device and AI in every service”.

Since joining Microsoft in 2018 through the FSLogix acquisition, I’ve been deeply involved in shaping Windows 365 and its community—starting from its earliest days as a Visio stencil. I’ve contributed to key innovations like Windows 365 Boot, Switch, and the Windows 365 app, and helped incubate the vision behind Windows 365 Link. My mission is to drive innovation across Windows 365, AI, Windows, and Microsoft Intune, while empowering customers through community and technical enablement.

I’m the author of five books, including the newly released Mastering Windows 365, and am currently working on Mastering Microsoft Intune – 2nd Edition, a follow-up to the 20k+ bestseller. I hold seven patents across cloud and virtualization technologies and have won six internal Microsoft Hackathons.

Before Microsoft, I was a Global Black Belt for Azure Virtual Desktop and have been recognized with community honors including Microsoft MVP, Citrix CTP, VMware vExpert, Parallels VIPP and Nvidia NEPA—an achievement held by only five people globally before I joined Microsoft.

I also co-lead the #DAASLIKEAPRO community survey, founded the Microsoft meets Community: Windows 365 event (aka.ms/w365event), and host the Windows in the Cloud video podcast (aka.ms/WindowsintheCloud). I regularly speak at global conferences like Microsoft Ignite, Citrix Synergy, VMworld, and more.

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.
