Plaza
A trust layer for finding collaborators you can actually vouch for.
找可信协作者的信任层
Overview
Plaza is a trust layer for finding people you can actually vouch for. Instead of an open feed of strangers, it verifies each person through GitHub proof-of-work and LinkedIn, then matches you semantically and explains every match with a human-readable reason and its evidence.
Who it’s for
Founders, engineers, and builders looking for credible co-founders, collaborators, or hires — anyone tired of cold outreach and unverifiable profiles.
What it does
- Dual-source trust gateway: GitHub proof-of-work + LinkedIn verification
- Every match carries a human-readable reason and the evidence behind it
- Controlled DMs — zero-harassment by design
- Two verticals in one: collaboration and hiring
- Long-tail discovery pages for niches and roles
How it works
-
Two independent proofs
Verification draws on GitHub proof-of-work — what you have actually contributed — alongside LinkedIn. Two independent sources are harder to fake than either alone, which is the whole point of a trust layer.
-
Matching that shows its work
Semantic matching sits on top of the verified profile, and every match carries a human-readable reason and the evidence behind it. You can disagree with a match on the merits instead of guessing why it surfaced.
-
Contact is controlled
Direct messages are gated rather than open, so the failure mode of every open builder network — unsolicited volume — is designed out instead of moderated after the fact.

FAQ
What is Plaza?
Plaza is the polyagent trust layer: it verifies people (GitHub + LinkedIn), matches you by real signal, and gives each match a reason with evidence — so collaboration starts from trust, not cold outreach.
How does Plaza verify people?
It uses dual-source verification — GitHub proof-of-work (your actual contributions) plus LinkedIn — and layers semantic matching on top, so a match reflects demonstrated ability, not just a claimed title.
Where can I try Plaza?
Plaza is live at polyagent.club/discover.
Does Plaza cost anything?
No. Plaza is free and you can look around without signing up. polyagent Council, the multi-agent game alongside it, is also free and supports guest play.
