Lemma vs everything else.
We're not trying to replace LinkedIn. We're building what LinkedIn can't: a verification layer that actually means something.

Each one sets out what the other approach measures, what Lemma measures, and where the two genuinely differ.

The honest answer
Why LinkedIn skills aren't enough.
Anyone can endorse anything
LinkedIn skills require zero proof. They're traded as social currency between connections.
Employers stopped trusting them
Most hiring managers ignore LinkedIn skill endorsements. They've been gamed too many times.
No score, no signal
There's no score, no tier, no traceable evidence. 50 endorsements and 5 endorsements look identical.
Lemma is different
Every point on your Lemma score traces to a session, a proof, or a peer. Open formula. Open audit.
Certificates don't prove you can apply the knowledge.
Courses and certifications test recognition, not application. You can complete a React course without writing a single production component. Lemma tests what you can actually do – in a live session with someone who's been there.
