Where AI meets Event Sourcing
De Bazel, Amsterdam
October 1 - 2, 2025
Event sourcing isn't new—but making it easy, scalable, and practical for real-world systems? That's where the magic happens. At its core, event sourcing gives you the full story—what happened, when, and why—so you can build systems that are not only resilient, but deeply understandable. And in the age of AI, that complete historical context becomes your competitive advantage - feeding smarter models, enabling better predictions, and building truly intelligent systems.
For the fourth year in a row, we're bringing together the sharpest minds in event-driven architecture to move the conversation forward — not just around tools, but real-world tactics that matter in an AI-first world.
This year's conference will feature:
- Stories from the trenches: raw, unfiltered lessons learned from teams scaling event-driven systems in production and leveraging event streams for AI applications
- Workshops, masterclasses, and keynotes: hands-on sessions, deep dives, and expert talks to level up your skills in both event sourcing and AI integration
- Strategic sessions: from convincing stakeholders of the business value of Event Sourcing to exploring its intersection with AI, machine learning pipelines, and life beyond Axon
- Networking: connect with developers, architects, and CTOs shaping the future of event-driven systems and AI-native architectures from some of the most recognizable company names in the world.
We're here for the builders. The ones knee-deep in distributed systems and AI implementations, not whiteboard fantasies. If you want to get smarter about event sourcing and its role in building intelligent systems, and walk away with something you can actually use, this is your conference.
