About

A non-profit public accountability platform

Plumbline organizes publicly available information about consumer-facing businesses into one transparent, evidence-based resource, so consumers can make informed decisions from documented facts.

Mission

Plumbline exists to help consumers make informed decisions by documenting publicly available corporate conduct using verifiable evidence. Every company is measured using exactly the same published methodology. The standard never changes. Only the measurement changes.

What Plumbline is not

How the platform is governed

Every edit, approval, correction, publication, deletion, and role change is written to an audit log with a timestamp and the responsible reviewer. The audit log is append-only.

No advertising, no sensationalism

The platform carries no advertisements and publishes no clickbait. Headlines use the language of the underlying document. Where a record is thin, the profile says so rather than filling the gap with inference.

What we are building toward

Each of these extends the same architecture: research assists, humans review, administrators publish, and every statement links to its source.
