about this event

DevDay Exchange London: Community Hackathon. Join us for a day of building with Codex and OpenAI, ahead of DevDay Exchange London. We're bringing London builders together to meet, find teammates and make something useful or fun. Spend the day working on an idea, trying out new workflows and sharing what you've built with the London community.

How it works: Come with a team or find people to build with when you arrive. Bring your laptop and an idea you want to try. We'll start with coffee, introductions and the opening brief, then get straight into building. There'll be food and drinks throughout the day, time to meet other builders, and demos, judging and prizes to finish — plus a few exciting surprises to keep you entertained while your agents are working ;)

Prizes: Tickets to the official DevDay Exchange London, OpenAI API Credits, and ChatGPT Pro Subscriptions. Judges: TBA.

The day: 09:00 — Arrivals, coffee and team finding. 10:00 — Opening brief. 11:00 — Build, with lunch at 13:00. 17:00 — Submissions close, dinner and first-round judging. 18:00 — Final demos. 19:00 — Awards, photos and close by 19:30.

Community important details: Doors will close at 9:30am and no entry will be permitted after this time due to security and venue constraints. Maximum team size of 4 people. The meetups demand is overwhelming, with over 1,000+ registrations each; we will try to make sure as many people can attend as possible, but space is limited.

Hosted by Andy T — Codex Ambassador, London, and the Outpost Team.
