Luise Freese

Luise Freese

Luise is an Azure & Power Platform Architect based in Germany. She is an awarded Microsoft Most Valuable Professional (MVP) working with organizations that want to move beyond digital theatre. Her focus is on AI-enabled solutions that are designed to last in real-world environments.

Alongside client work, Luise writes and speaks about productivity myths, pseudo-agile practices, AI readiness, and why many digital initiatives fail long before technology becomes the problem. She is known for combining clear technical guidance with a sharp eye for organizational patterns; and for asking the uncomfortable questions others tend to avoid.

When not working and traveling, she is a runner, a mother of (teenage) dragons, a LEGO-builder and a lover of the number 42. Her favorite color is #ff69b4.

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

Most Active Speakers 2023

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 2023.

The 3% is calculated from the pool of all speakers that have at least one accepted session in year 2023. We don't include inactive speakers or speakers that had no accepted sessions during the year. There are around 25 thousand unique accepted speakers this year, the 3% is 771. 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 2023. 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.
