Skills should be proven, not claimed.
The market for skill proof is broken. Resumes inflate, endorsements trade as social currency, and degrees measure where you went — not what you know. We're fixing that with a verification layer anyone can trust.
Three broken signals. One broken market.
Resumes inflate by design.
The incentive structure for resumes is broken. Every candidate exaggerates. Every hiring manager discounts. The inflation is so universal that it destroys signal for everyone — including honest candidates.
Endorsements are social favors, not proof.
Click-based endorsements carry zero accountability. You endorse me, I endorse you. A hundred LinkedIn endorsements for Python tells you nothing about whether someone can actually write Python.
Degrees measure time, not capability.
A CS degree from a top university guarantees four years of study — nothing more. It doesn't tell you if the person can ship, debug, or explain a system simply to someone who needs to understand it.
“We believe real skill is earned, not claimed. Every session someone teaches is proof they know. Every session someone learns is progress. That exchange should leave a permanent, auditable record — one that outlasts any resume, any platform, any employer.”
How Lemma embodies the mission.
Not just a statement — a system designed around proof at every layer.
Evidence over assertion
Every skill claim on Lemma is backed by an immutable event log. Completed sessions, passed assessments, peer endorsements — all recorded permanently. Nothing can be altered retroactively.
Peer validation over self-report
Real practitioners validate real skills in real sessions. Endorsements carry weight proportional to the endorser's own credibility score. Empty endorsements have no value here.
Open formula over black boxes
The SCI formula is published, versioned, and fully documented. Every point is traceable to a specific event. No hidden biases. No pay-to-win. No mystery.
Portable proof over platform lock-in
Your skill passport belongs to you. Share it anywhere, with anyone. Built on open APIs so your evidence can follow you across every context that matters.
Join the movement.
Every session completed is another point of proof in the world. Come be part of that.
