How it works

Build a real AI product in 24 hours

This is not a pitch competition or a slide deck event. VibeHack London is a full weekend for people who want to build fast, experiment hard, and bring AI ideas to life.

01

UCL Great Ormond Street Institute of Child Health

Schedule, judges, workshops, sponsors, and prize details will be announced before the event.

02

Start a 24-hour build sprint

Students, early builders, developers, designers, medics, and researchers gather at UCL to move quickly from idea to prototype to working product.

03

Demo a live working AI product

No concept-only pitches and no story-only decks. Teams must show a live working AI product and convince the judges through a real experience.

Prizes and perks

Prize pool, AI tools, and the Vibe Coder award

Judging rewards creativity, execution, usability, technical skill, and real-world potential. More details on judges, workshops, sponsors, and prizes will be announced before the event.

The challenge

Built for people who actually want to make things

You can build a health tool, an AI workflow product, a new consumer app, or something completely unexpected. The point is to make something demoable within a limited time.

24h
You have 24 hours to build and ship

Move from idea to prototype to a demoable product in one intense product sprint.

Build
Live
You must demo a live working AI product

No slides-only submissions and no concept-only pitches. The room needs to see the product actually work.

Demo
Judge
Creativity, execution, usability and technical skill

Judging is not about who talks best. It is about who builds something clearer, more usable, and more promising.

Score
Vibe
This is for people who actually want to make things

Technical and non-technical builders are welcome. You do not need to be a full-time engineer, but you do need to be ready to build.

Ship
Who should join

Builders, developers, designers, researchers and founders

Open to students and early builders from UCL, Imperial, KCL, Queen Mary, LSE, and the wider London ecosystem.

AI

Curious about AI native products

If you are into vibe coding, AI-native products, rapid prototyping, and shipping, this is for you.

Technical and non-technical builders

You do not need to be a full-time engineer. Product, design, medical, research, operations, and startup-minded people are welcome to team up.

Come build. Come ship. Come vibe.

London has no shortage of smart people. What's rarer is getting them in one room, with the right tools, under time pressure, and asking them to actually build.
