Buildathon London 2026 - Shared Futures Foundation: Public Demo Day Begins 7:00 PM

​Public Demo Day: 7:00 PM - 10:30 PM

​24 hours. £30,000 in grants.
Build something people will actually use.

​Most hackathons end with demos that never go anywhere.

​This one doesn’t.

​On June 7, 120 builders come together in London for a 24-hour sprint. The goal is simple. Build a product that should exist, and get it into the world.

​Three teams walk away with £10,000 each.
The strongest teams don’t stop there. They move into a 90-day incubation with real support behind them.

​What you’ll be doing

​You’re building something real.

​Something someone could use next week.
Something you’d actually continue after the event.

​Most of what people use today was not built with them in mind. That’s the gap.

​You get 24 hours to close it.

​The tracks

​You’ll build in one of three directions.

​Signal
Media, content, distribution
Tools that help people create, share, and access information without relying on the usual systems

​Circuit
Everyday infrastructure
Finance, commerce, productivity, local systems people depend on

​Interchange
Open
If you see something broken and know how to fix it, build it
