LinkedIn Endorsements
Popularity contest, not skill proof.
- Anyone can endorse without verification
- No evidence of actual skill level
- Endorsements can be easily gamed
With Lemma
Every skill backed by evidence.
- Skills verified through AI assessments and peer sessions
- SCI score with full evidence trail
- Tamper-proof verification via API
Certificate Platforms
Completion is not competence.
- Certificates prove course completion, not skill mastery
- No ongoing verification or skill decay tracking
- Easy to share credentials without retaining knowledge
With Lemma
Living proof that evolves with you.
- Continuous assessment tracks skill growth and decay
- Real-time SCI score reflects current ability
- Evidence from multiple sources: sessions, AI, peers
Traditional Hiring
Interviews measure interview skills.
- Whiteboard problems do not reflect real work
- Unconscious bias affects evaluation
- Expensive and time-consuming process
With Lemma
Hire based on what candidates can do.
- Objective skill scores from standardized assessments
- Bias-reduced evaluation through blind skill data
- 10x faster screening with API integration
Self-Assessment
People overestimate their own skills.
- Dunning-Kruger effect makes self-assessment unreliable
- No external validation or calibration
- Impossible for employers to trust
With Lemma
Third-party verified skill data.
- Independent AI and peer assessment removes self-bias
- Calibrated scoring against global skill benchmarks
- Employers can verify skills programmatically via API
