Trade what you have. Get what you need. No money required.

An algorithm finds chains of exchange that connect your surplus to someone else's need, through businesses you'd never have thought of.

You have time on Friday afternoons. A theatre needs accounting help. They can offer rehearsal space. A design studio needs that space. They can do branding for a cafe. The cafe can cater your next event.

An algorithm finds these chains in seconds. Connections you'd never spot yourself. Everyone gives what they're not using. Everyone gets what they need. No cash changes hands.

This is a proof of concept: working code exploring how AI could solve the matching problem that money was invented for.

Hard questions, honest answers

We've analysed the hard questions (accountability, trust, governance, bad actors, transparency) in depth. Where we don't have answers, we say so.
