Plaza is a trust layer for finding collaborators. It unifies GitHub proof-of-work, LinkedIn professional identity and live availability into a single structured signal that answers three questions about any potential collaborator: are they credible, are they open to collaborating right now, and is it safe to contact them?

How does Plaza verify that a builder is credible?

Plaza uses a dual-source trust gateway: you sign in with GitHub and LinkedIn, anchoring identity to both your work graph and your career graph. A Trust Score is then composed from verified activity — real commit history and ownership evidence — not self-declared claims.

How does matching work?

Plaza matches collaborators by meaning, not keywords, using semantic embeddings of skills, projects and needs. Every recommendation comes with a human-readable Match Reason — no match is ever shown without explaining why.

Will Plaza spam my inbox?

No. Contact is controlled — it can only be initiated through a structured collaboration request, and raw contact details are never exposed. It is built to eliminate cold-DM spam.

How much does Plaza cost and when can I use it?

Plaza is in early access development. Join the waitlist and we'll email your invite when it opens — no charge to register interest.

Privacy

What we collect, in plain terms.

Last updated 8 August 2026. Plaza is operated by DUOCODE TECHNOLOGY ("we", "us") and is part of the polyagent product family. Questions go to duocodetechu@gmail.com.

What we collect

A waitlist email. If you ask for early access, we collect the email address you submit. The form is delivered through Web3Forms, which passes the submission to our inbox on our behalf. That is the only thing you hand us directly.

Usage analytics. We use Google Analytics 4 and Vercel Analytics to see which parts of Plaza get used. These record page views, interactions, an approximate region derived from your IP address, and a client identifier stored in your browser. We do not use any of it to build advertising profiles, and Plaza shows no ads.

What we do not collect

No location, contacts, photos, files, health data, or payment details. Plaza has no in-app purchases, and today it has no sign-in — so there is no account, no password, and no connected GitHub or LinkedIn data. If and when connecting an account ships, this page will say so before it collects anything.

How we use it

To run the waitlist and let you know when Plaza opens, and to understand how the product is used so we can improve it. We do not sell your personal data.

Who else touches it

Only the service providers that make Plaza work: Web3Forms (waitlist delivery), Vercel (hosting and analytics), and Google (analytics). Each processes data solely to provide its service to us.

Your choices

Email duocodetechu@gmail.com to see, correct, or delete what we hold — in practice, your waitlist entry. You can block analytics cookies in your browser and still use everything on the site.

How long we keep it

Waitlist entries stay until you ask us to remove them or the waitlist closes.

Children

Plaza is not directed at children under 13 and we do not knowingly collect data from them.

Changes

We will update this policy as the product changes; material changes show up in the date at the top.
