Barcelona AI Hackathon

Three tracks. €10,000 to the team that ships the best build.

Friday evening you get the theme. Saturday afternoon you demo. Everything in between is yours.

The challenge

Coding agents have changed what four people can build in a day. This is where we find out how much.

You get the theme at kickoff. You get thirteen hours of build time across two days. You ship something that runs in a mobile browser and that a stranger can pick up and use in 60 seconds.

Any stack. Any model, any agent, any tool you want.

No pitch decks. No business models. No slides. You hand someone a phone and they use it, or they don't.

Pick your track

Ship a game. Something playable in 60 seconds. Any genre, any mechanic.

Ship a tool. Productivity. Pick a task a real person does by hand every week and build the thing that does it for them.

Ship a habit. Something for health, fitness, sleep, food — anything that makes a person do the right thing tomorrow.

Choose your track when you apply, or decide on the Friday once you've seen the theme. Each track gets its own winner.

€10,000

To the winning team. Cash.

How it's judged

Saturday afternoon, every build goes live and everyone in the room tries everything.

The €10,000 is decided by the jury — the AI Lytvyn Foundation, our mentors, and the organising team. Four things they're looking for:

Is it good. Is it actually finished. Is it original. And how hard did you push your agents to get there.

Every team publishes their setup afterwards: models, tools, prompting approach, total tokens burned. By Saturday night we'll know exactly what fifteen teams shipped in thirteen hours and what it cost them.

Teams

Up to 4 people. Bring your own team, or come solo and we'll match you on the Friday.

Who this is for

Working engineers, technical founders, and anyone already building seriously with coding agents.

You don't need to have built anything like this before — most people here won't have. You need to be able to ship.

Bring

Your own laptop. Your own AI subscriptions and API keys — Claude, ChatGPT, Cursor, whatever you already run on. Come with your setup working and your environment ready, so the clock goes on building instead of installing.

Included

Free entry. Food and drinks across both days. Mentors. Afterparty. A room full of people who ship.

70 places

That's the whole room, and we're keeping it that way on purpose.

Applications are reviewed — this is not a ticket. Apply below and we'll come back to you within a few days.

Venue announced shortly — central Barcelona. Powered by the AI Lytvyn Foundation.
