The ACCU on Sea 2026 Call for Speakers runs until midnight (GMT) on Sunday, 11th January 2026.
So you'd like to present at the ACCU on Sea? Great! We look forward to and welcome submissions from everyone, including those who may feel underrepresented or overlooked.
The conference will run from 17th-20th June 2026, with pre-conference workshops days on the 15th-16th.
The main conference will mostly feature 60 or 90-minute presentations and workshops, with a few 20-minute slots available, too. Lightning talks will run on several evenings, but will be organised closer to and during the event.
The workshop days are ticketed separately, and instructors will get a share of the revenue.
This year's event will be entirely in person, but we also run an online-only event, C++ Online for those who prefer the online experience.
What should I present on?
ACCU on Sea is the confluence of the C++ on Sea and ACCU conferences. As such we will present 2-3 tracks of pure C++ (the C++ on Sea component), with approximately two tracks dedicated to non-C++ topics (the ACCU component).
For the ACCU tracks we are interested in submissions on different programming languages, tools and practices. Even non-technical topics that are relevant to software development professionals are welcome.
For the C++ on Sea tracks we certainly welcome bleeding-edge C++ topics - especially with C++26 rounding out this year - but we don't want to lose sight of what people are actually using day-to-day. We're also interested in popular applications of C++ in the real world. To that end we encourage submissions on (but not limited to) the following topics and themes:
- Contemporary C++ (C++23, 26 and beyond)
- Bread-and-butter C++ (basics/ fundamentals)
- C++ in Games Development
- Low-latency C++
- Safety and Mission Critical C++
- C++ Tools
Who should present?
We want to put on the best conference possible. We believe that this means hearing from voices from different backgrounds and experience levels. As part of this commitment, the main round of submission reviews is anonymised (so please try to avoid including personally identifiable words or phrases in your title, abstract and outline).
We'd also like to make especially clear that people from all backgrounds - minorities or otherwise - are not only welcome, but we will do whatever we can to actively support you. If you have any questions or concerns about this, always feel free to contact us.
How long do I have?
The Call For Speakers will remain open until midnight (GMT) on 11th January 2026. But don't wait until then! Those last-minute, rushed, submissions are never as good as those you have set aside the time, early on, to do properly.
Here's the complete timeline that we aim to follow for the 2026 speaker call:
- 8th November 2025, CfP opens
- 11th January 2026, CfP closes
- Programme Committee reviews
- Early February, acceptances start to be sent to speakers
- End of February, scheduling begins
- 2nd March, Schedule announced
This timeline is subject to adjustment, but we aim to keep to the above as far as possible.
If you submit please ensure you will be available the first week of February to be able to confirm your acceptance.
Please note that acceptances are sent out in batches, so if you haven't heard anything straight away it dosn't mean you have not been accepted.
