Cosign guidelines
Cosigns are only valuable if people can trust them. These guidelines keep it that way.
Write cosigns that help
- Be specific. Name a project, a decision, a moment. Explain the outcome.
- Say how you know them. Co-founder, manager, investor, customer — context helps readers weigh your words.
- Pick what they’re known for. Choose up to three strengths you’ve seen first-hand.
- Cosign early. The most valuable cosigns back people before everyone else does.
Not allowed
- Cosigning yourself, trading cosigns, or paying or being paid for them.
- Endorsing someone you have no first-hand knowledge of, or misrepresenting your relationship.
- Negative reviews, harassment, discrimination, or sharing private or confidential information.
- Spam, promotion unrelated to the person or company, or impersonating anyone.
- Fake profiles or companies, or profiles created to mislead.
Signals and lists
Signals are private expressions of interest — use them sincerely. Lists should be built around a clear, honest theme. Community rankings are for nominations you genuinely believe in.
