What we’re about
Launched in May 2024, we offer a welcoming platform in Vienna for C++ developers to network, share knowledge, and grow together. Whether you’re a seasoned professional or a curious newcomer, you’re invited to join us.
We host monthly user group meetings with C++ news, technical talks, and opportunities to discuss your own challenges if you wish. And sometimes we simply meet just for fun 😉
Sounds great? Get in touch!

Double Feature: 👀 Travel Report Meeting C++ 2025 & 📜 Paper Discussion P3747
FAV Hörsaal 3 Zemanek, Favoritenstraße 11, Vienna, AT📢 Main event starts at 18:30 CET
📍 Location diffs from last time
✨ René Paris, Helmut Hlavacs and Thomas Mejstrik
We'd like to invite you to a special community DOUBLE FEATURE! 🎬
Part 1: Gone in 30 Minutes
René Paris and Helmut Hlavacs will kick off things while the memories are still fresh, sharing their personal highlights from the recent Meeting C++ 2025 conference. A compressed version of three intense days of newest C++ insights in about 30 minutes 👟
✨ But wait, there’s more!
Part 2: The Return of the Unknown
Thomas Mejstrik takes us into the realm of template return argument deduction, as suggested in his paper P3747. Starting with a refresher on the fundamentals of template argument deduction (tales from function calls and conversion function templates), he guides us through current limitations of deduction rules and how the proposed changes to C++ will simplify code, reduce boilerplate, and improve expressiveness; By clever reuses of existing deduction mechanisms without break existing code. Meet the artist himself in an an open discussion and give him the proper audience, like a true C++ committee. So bring your questions and challenge his reality on sane C++.
🚨 All jokes aside: Help us to gather honest feedback on his proposal. Return insights and delete bad ideas and finally we might find out whether the idea should move forward or simply go to void.

⚡ Lightning Talks Session ⚡
FAV Hörsaal 3 Zemanek, Favoritenstraße 11, Vienna, AT📢 Main event starts at 18:30 CET
✨ Maybe you hear yourself speaking?
As is becoming our year-end tradition, we’re celebrating with community-powered Lightning Talks!
And what could be more satisfying than listening to the one person you trust to speak expertly about absolutely anything on Earth—yourself?
So if you have an idea that’s at least somewhat connected to C++, even if only by a frayed peripheral thread, bring it on. Nothing is boring (except in the wrong company 😉). Wild, quirky, or gloriously unhinged? Why not?!
Reach out as long as the speakers’ table isn’t full yet! We promise the experience will be sparkling… and maybe even a little touching.
