🇫🇷 Oz Builder Day: 24-Hour AI x Web3 Hackathon
Oz Builder Day is a 24-hour hackathon hosted by The Oz city — a deep dive into benchmarking, prototyping, and pushing the boundaries of Web3 and AI.
Whether you're starting fresh or scaling an existing project, this is your chance to build with focus, backed by a hands-on mentor community.
Throughout the event, experienced mentors and coaches will work side by side with participants, helping early-stage ideas evolve into working prototypes, and helping advanced teams refine new features, explore GTM strategies, and benchmark their progress.
👥 Who’s Attending
This edition of Oz Builder Day brings together:
Oz City residents – developers, founders, and researchers already building with us
Local talent – builders from the Côte d’Azur tech scene
We expect up to 70 Web3 and AI developers attending Oz City just before ETHCC Cannes.
