Join us for DevDay Exchange Community Hackathon: Berlin, hosted by Max Jendrall, your local OpenAI Codex Ambassador in Berlin! Build something useful with Codex and ChatGPT alongside Berlin's developers, students, founders and go-to-market builders. This community-led hackathon is a chance to explore ideas and tools from DevDay, exchange practical workflows and find collaborators ahead of Berlin's official DevDay Exchange and maybe get a chance to win a ticket to the DevDay Exchange on the 26th. Saturday, 24 October 2026 · 10:00-18:00 CEST. The plan includes Developer, GTM and Founder tracks, all centred on building with Codex. The detailed timetable and track-lead assignments will be confirmed before the final announcement. Bring a laptop, a project idea or a work in progress, and spend the day making progress with other builders. Whether you use Codex and ChatGPT every day or are still exploring agents, you're welcome to apply. You don't need a finished project: tell us what you've built so far, or what you'd like to try. Registration Attendance is free and subject to host approval. Please include your LinkedIn profile when applying. The additional account, organization, food-planning, company/role and project questions are optional. Never enter API keys or secrets.
