C++ Online 2027: Calls for Speakers and Workshops Now Open
As a community partner of C++ Online 2027, ACCU on Sea is pleased to help promote the conference's Calls for Speakers and Workshops and encourage members of the C++ community to get involved.
Taking place from 10–12 March 2027 (12:00–22:00 UTC), C++ Online brings together C++ developers from around the world for three days of online talks, followed by a programme of workshops and training sessions running from April to June 2027.
The Call for Speakers is open for 30, 60 and 90-minute talks covering all aspects of C++. Talks will be livestreamed to a global audience, available on-demand and published to YouTube after the event. Speakers receive complimentary access to the conference, and pre-recorded talks are also welcome.
Speaker submission deadline: 20 November 2026.
Find out more and submit a talk proposal.
The Call for Workshops welcomes proposals for half-day, full-day and multi-day online training sessions. Instructors receive a 50% revenue share on registrations, complimentary access to the main conference and the opportunity to promote their workshops through optional preview sessions during the event.
Proposals are reviewed on a rolling basis, with an early December 2026 soft deadline for workshops seeking a preview session during the main conference.

ACCU is delighted to support C++Online in bringing the global C++ community together. If you have knowledge, experience or ideas to share, why not consider submitting a proposal?
A huge thanks to our platinum sponsor for 2026, Bloomberg Engineering

Bloomberg have been a regular sponsor of both events for many years and a big supporter of our community. So we're really pleased that they are continuing their support of our combined event at the platinum level!
Let's hear from them why they do it:
Bloomberg is building the world's most trusted information network for financial professionals. Our 9,000+ dedicated engineers are advancing and building new systems for the Bloomberg Terminal to solve complex, real-world problems.
C++ is one of our core programming languages. We constantly push the language to its limits because our code must be scalable, reliable, and extremely fast — especially since every microsecond counts in finance.
Our C++ experts build everything from low-level libraries and components to some of the world’s most performant financial applications, analytics, and trading systems. They also contribute to the C++ Standards Committee (WG21).
Thanks to Ripple for returning as Gold sponsor
Ripple partnered with us a couple of years ago (at C++ on Sea), so we're pleased they have decided to come back as Gold sponsor.
To tell you more about who Ripple are and what they do, let's hear directly from them:
Founded in 2012, Ripple is the leading provider of blockchain-based enterprise solutions across traditional and digital finance. Its solutions span global payments, custody, liquidity, and treasury management, serving as a one-stop shop for moving, storing, exchanging, and managing value. Ripple’s stablecoin, RLUSD, and the cryptocurrency XRP underpinning these solutions allow Ripple and its customers to shape the modern financial system.
