Sander Hoogendoorn

Sander Hoogendoorn

Sander Hoogendoorn is an independent dad, avid traveler, and lifelong software developer. With over 40 years of hands-on coding experience under his belt, he still ships code every day — because once a developer, always a developer.

Currently the CTO at iBOOD, Sander has led technology at companies such as ANVA, Quby, and Klaverblad, and was once Capgemini’s global agile thought leader. But don’t expect corporate buzzwords — Sander’s known for cutting through the fluff with a post-agile mindset and a healthy disregard for outdated best practices.

He helps teams and organizations break rules that need breaking — replacing heavyweight processes with lightweight thinking, and agile dogma with actual flow. If something’s slowing your team down, chances are he’s already ranted about it in a keynote.

Onstage, Sander brings code, stories, and sharp insights — whether he’s talking disruption, continuous delivery, microservices, monads (yes, really), software architecture, or the lost art of elegant code. His talks are fast-paced, thought-provoking, and never just theory.

Sander believes in small steps, critical thinking, and building stuff that works. No silver bullets. Just better software, made by better teams.

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.
