How it works

Post. Match. Show up.

One loop, built around trust. Here's the whole thing.

1 · Post

Describe your open slot in a phrase — “need 2 for football tonight” — and the AI drafts the full listing. Set slots, time, price (or free), and publish in under a minute.

2 · Match

People nearby see it ranked by compatibility. They tap “I’m Interested”, you review their Passport — attendance rate, reviews, verification — and accept, waitlist, or pass.

3 · Show up

Accepted members unlock group chat and the exact address. Paid slots sit in escrow until kick-off. Afterwards, both sides review each other — blind, so it stays honest.

Last Minute Rescue™

A dedicated, countdown-driven shelf for opportunities starting within three hours — the ticket that would otherwise expire, the game that's one short tonight. It's the fastest path from "we're missing someone" to "they're on their way."

Opportunity Passport™

Your portable reputation: events attended, show-up percentage, star ratings, and earned badges — visible to hosts at the exact moment they choose who joins. Reviews are mutually blind for 14 days (or until both sides submit), so feedback stays honest without being awkward.

Escrow payments

For paid slots, your money is held by Joinza — not the host — until the event's confirmed start. Hosts choose a refund template up front (Flexible, Standard, or Strict) and it's enforced automatically. Host cancels? Full refund, every time.
