Room

London's live tech demo night.

3 slides max.
No pitches.

What this is

A celebration of the London tech scene, one working demo at a time

Come show your projects. Whether it's AI, robots, networks, hardware, quantum, or weird side projects — there will be a room that's rooting for you!

The format

Three kinds of slot

2 min

Show & Tell

Lightning slots, perfect for first-timers. Plug in, show one thing, take the applause.

10 min

Feature Demo

A proper walkthrough of something you've built, with time for questions from the room.

20 min

Headline

One per night. The big one — or a full dress rehearsal for a demo you're taking somewhere scarier.

The practice ground

Rehearse the big one here

Got a conference talk, a product launch, or an investor demo coming up? Run it in the Demo Room first — in front of a warm technical audience, on a night where nothing is at stake.

Flag your slot as a practice run and tell us what you're preparing for. You'll leave with honest, friendly feedback and a demo that's already survived contact with a live room. And you won't be doing it alone:

Everything to put every chance in your favour before the night that counts.

Who it's for

Builders of every kind
