Built on evidence. Not on claims.
Every score is traceable. Every point has a source. Our methodology is public, versioned, and open to audit — because trust requires transparency.
Four properties that make verification real.
Event sourcing
Every skill interaction is recorded as an immutable event. Evidence accumulates over time and cannot be altered retroactively.
Peer validation
Skills are validated through real interactions with real people. Endorsements are weighted by the endorser's own credibility.
Adaptive assessment
Assessments calibrate in real time. Pass three in a row and the bar rises. The system finds your true edge.
Open formula
The SCI formula is documented publicly. Every component, every weight, every version. Nothing hidden, nothing opaque.
Five systems. Each documented in full.
Every part of our methodology is published, versioned, and open to inspection.
SCI Score
Skill Credibility Index
A composite 0–100 score built from four independently weighted components. Every point is traceable to a specific event.
Trust Tiers
Trust Tiers
Six tiers from Newcomer to Authority. Each tier requires specific, verifiable evidence and unlocks new opportunities.
Evidence
Evidence Types
Not all evidence is equal. Here's exactly what counts, how it's weighted, and how it gets onto your passport.
Matching
Matching Engine
Twelve signals. Zero self-reported data. The algorithm that finds the peer you actually need.
Sessions
Peer Sessions
Structured, time-boxed interactions where both participants demonstrate skills and generate immutable evidence.
Why we published our methodology.
- Every formula component is versioned and documented
- Historic scores are replayable from the event log
- No black boxes — open to academic and employer scrutiny
- Formula changes are announced publicly before taking effect
