Find a C++ collaborator you can trust.
Plaza matches you with verified C++ builders — systems and performance-critical engineers — whose credibility comes from measured public GitHub work — repository languages counted in bytes, push dates and stars, not a self-declared bio. Every match arrives with a reason, the repositories it was measured from, and the arithmetic that ranked it.
Three questions, answered before you reach out.
Credible
A Trust Score built from verified C++ activity and ownership evidence — real commits, not claims.
Still shipping
Measured recency tells a technical co-founder, open-source maintainer or collaborator candidate who pushed C++ this quarter from one whose last commit was two years ago.
Nothing to spam
Plaza publishes no contact details and has no messaging: you read the evidence, then open the builder's own GitHub. Nobody's inbox is sold, flooded or exposed.
Before you search.
How do I find a trustworthy C++ collaborator?
Plaza ranks builders on evidence measured from their public repositories, not on claims. It reads a builder's public GitHub account — repository languages counted in bytes, push dates, stars and topics — computes a Trust Score from that activity, and ranks every match as 0.85 × skill-evidence coverage + 0.15 × trust score. The arithmetic and the repositories behind each result are shown, and a builder with no measured evidence for a skill you asked for is never returned. For C++ specifically, that means the C++ in a profile was counted in their repositories, not typed into a bio.
Can I find a C++ co-founder on Plaza?
Yes. Search for C++ and Plaza ranks every indexed builder by measured C++ evidence — 0.85 × skill-evidence coverage + 0.15 × trust score — and never returns someone with no C++ evidence at all. Searching is free and needs no account.
Can I contact someone through Plaza?
Plaza publishes no contact details and has no messaging, so nothing here can flood an inbox: you read a builder's measured evidence and open their own GitHub yourself. Collaboration requests are not built yet — the waitlist is how you hear when they are.
