AI Builders
Weekend
100 Builders. 48 Hours. Hackathon meets LAN party. We're bringing back the raw community energy of late-night LAN parties, combined with modern AI product development, live workflows, and retro gaming.
Whether you're a non-tech enthusiast, active founder, or senior engineer: join us to build, compete, or spectate and learn how real AI products get built live, from scratch.
First come, first served.
The room holds 100 builders and 100 spectators, and applications are reviewed in the order they arrive. Joining the list early is the single biggest thing you can do to get accepted. There is no second queue and no way to jump it later.
Pick builder or spectator. It isn't final. The list is notified first and you decide then. Dates, venue, prize pool and full format follow soon, to the list before anyone else.
You're in the queue. We'll email with dates, venue and everything else before it goes public.
Save this link. Everyone who joins through it improves your chances of getting a seat when applications open, and there is a special gift from the organisers for people who bring others along.

What a seat is worth
The cash prize is the smallest thing on this list.
- Prize poolReal money for winning teams, split so beginners compete against beginners. Figure published once partners are locked.
- Sponsor prizesSeparate awards from partner companies: hardware, credits, subscriptions, category bounties.
- Hiring without the CV screenCompanies recruit from the floor. They watch you work for 48 hours. The most honest interview that exists.
- Investors in the roomEarly-stage funds and angels watching you build and pitch. Some teams leave with a first conversation.
- Mentors on the floorSenior engineers, founders and operators, there the whole weekend, looking at your work.
- A permanent place in the communityEvery participant gets a public profile on our platform with your skills, your background and a portfolio of what you shipped, seen by every partner company, investor and founder in the network, long after Sunday.
- Speakers & panelsPeople shipping AI products in production, not keynote theatre.
- LAN night & afterpartyCounter-Strike 1.6, Quake III, and the part of the weekend nobody posts about.
Build against a real problem.
Manufacturers, logistics firms, clinics, banks and factories bring a problem that costs them money every week. Teams can build against one of those instead of an open brief, with the company sitting on the other side of the table.
For the team
A real user, real constraints, and a company with budget and a reason to sign a pilot on Monday.For the company
Several independent attacks on the same problem in 48 hours, plus direct access to whoever solved it.Open track
No partner brief. Build the thing you've been carrying around. Same jury, same prizes.The community lives in Telegram.
Not just announcements. It's the community channel, where builders find teammates, trade tools and workflows, and talk to the people organising it. Dates, venue, prize pool, speakers and the moment applications open land here first, before the emails go out.
