A founder signal is an observable behavior revealed during venture experimentation.
Signals appear in what a person does under uncertainty - not in what they declare in an application form.
- Behavioral, observed across multiple loops
- Tied to specific evidence the founder owns
- Opt-in, granular, withdrawable
- Always visible to the founder before anyone else
- Personality tests
- Hidden scoring systems
- Psychological profiling
- Surveillance of participants
- A black-box ranking sold to third parties
