🇫🇷 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.
