Call for proposalsSubmit your session today

The CFP officially closes on May 31, 2022.

Call for Proposals

Types of sessions

We're looking for long talks (50 minutes) or lightning talks (10 minutes), as well as post-conference workshops of 4h - 24h total length.

Should I submit my idea?

Yes, definitely! Submitting proposals is your job. Worrying about what fits the program is ours. When in doubt, submit it. To aid both new and experienced speakers, we offer support to help you develop your unfinished ideas into a great session


We're looking for all kinds of talks: deeply technical topics, EventSourcing patterns, case studies, advanced subjects like dealing with migration / legacy / evolution / hybrid solutions / bitemporality... Also CQRS, messaging, databases, ops,... Basically anything that is relevant to EventSourcing.


We love practical sessions! An ideal workshop:

  • ...favours practice over theory
  • ...can range from experimental to well-known formats
  • ...puts the 'work' in 'workshop': coding, modelling, drawing, writing, discussing, …
  • ...encourages collaboration between participants (eg pairing or team work)
  • ...makes you want to go to the office on Monday and change the way you work!
Programming languages & Technologies

The conference does not focus on any particular programming language or technology.

Spoken language

All sessions are in English. If you have ideas but can't do it in English, let us know, we might have other options outside of the conference.

Submission Process

Submission Process
  • Send us as many proposals as you’d like, before the submission deadline.
  • Even before the deadline, we might start accepting proposals, so being early helps.
  • We might ask you to have a short conference call with us. Sometimes we like to ask for clarifications, or suggest changes to the contents or the format. If we contact you for such a call, it is not a guarantee your proposal will be accepted.
  • We’ll notify you in the weeks after the submission deadline whether your idea is accepted or not. We'll ask for a final confirmation before announcing you.
  • Even after the you've been accepted, we'd like to help you make the most of your presentation or workshop. We'll put you in touch with other speakers, to help you develop your material, be your soundboard, and give you feedback. We might also ask you to do the same for others. We've found that even for experienced speakers, a bit of back and forth can greatly improve the presentation or workshop.
Increase Your Chances

Evaluating a submission based on nothing but an abstract is hard. Help us get to know you and your ideas by:

  • Sending us links to your content.
  • Blogging about your topic.
  • Talk about it at a local meetup. There are plenty of meetups across Europe, and most of them are happy to have new and inexperienced speakers.
  • Record your own video, ... Be creative!
  • Building a program involves lots of trade-offs, and often we have the painful task of refusing great proposals for other reasons than the topic. If yours is not accepted, please consider this an invitation to try again next year.
  • If you would like to pitch your product or service, we provide plenty of sponsorship opportunities. A 1-minute pitch at the beginning or end of your talk is acceptable.
