How it works
Submit Evidence
Upload documents, PDFs, or screenshots and provide a short summary of the misconduct you witnessed.
A Joint Community Effort
Rotten Company is maintained together by the community. Submissions are reviewed by other users against simple guidelines before acceptance.
Before submitting evidence for the first time, registered users complete a small number of moderation tasks when available. This shared responsibility keeps the platform credible.
Score Impact
Verified evidence updates the company's Rotten Score in the public index, helping others assess workplace risk.
Our principles
Evidence-Based
All scores are derived from submitted documentation, not opinions or anonymous ratings.
Moderated Submissions
Every submission goes through a review process before it can affect any score or appear publicly.
Protects Regular Employees
We focus on leadership decisions and systemic harm — not on individual non-executive staff members.
Governance & Fairness
- ✓Evidence-first moderation — every submission is reviewed against documented evidence before it can affect any score or appear publicly.
- ✓Remediation evidence — submit evidence of corrective actions; remediation is reviewed like any other evidence.
- ✓No anonymous scoring — all evidence submissions require a verified account; anonymous ratings are not accepted.
- ✓No paid removals or reputation laundering — scores reflect evidence only and cannot be purchased, boosted, or suppressed.
