Make your skills impossible to dismiss.
Lemma turns assessments, teaching, projects and real work into evidence-backed skill records, organised in a portable Skills Passport that grows with you.

The problem
Your skills already exist.
Their proof is scattered.
People build skills across courses, assessments, projects, teaching and work. The evidence stays divided between platforms, institutions and workplaces.

How it works
From real evidence to a portable Skills Passport.
Bring together evidence from learning and work. Lemma helps translate it into clear skill records that can be understood, inspected and shared.
Start with the evidence you already have.
Add assessments, coursework, projects, teaching activity and workplace contributions without forcing every source into the same shape.
See what the evidence actually demonstrates.
Connect each record to the skills it supports, the criteria it meets and the context in which the skill was demonstrated.

Share a record people can inspect.
Publish selected skill records in a portable Passport. A viewer can open a skill, inspect its evidence and understand how the result was formed.

The Skills Passport
A passport built to be opened, not simply accepted.
Each skill leads back to its evidence. View the source, context, criteria, date and current verification status without requesting another document.
Public by default
Your passport is a shareable URL — no login required for viewers. Link it from a CV, email, or LinkedIn in one click.
Append-only evidence
Every session and proof event is append-only. No retroactive edits, no inflated scores — the ledger is append-only.
Lives where you share it
Embed your passport link anywhere. Employers see the full breakdown: sessions, SCI, tier, and peer ratings — all in one place.
Grows with you
SCI is a living score. As you complete sessions and earn endorsements, your passport updates automatically — no renewal needed.
Evidence sources
Built from what you actually do.
Capability does not come from one source. Lemma captures the different ways people learn, contribute, solve problems and demonstrate progress.
Matched by signal, not by bio
Twelve signals – skills, goals, timezone, reliability – find the peer you actually need.
Who it is for
Built for people who develop, demonstrate and discover skills.
The same evidence can help someone communicate their ability, improve a learning experience, or support a better talent decision.
Carry your progress with you.
Bring evidence from different parts of your life into one record that can continue across roles, programmes and platforms.
- Live sessions with practitioners who built the thing
- Matched by skill, timezone, and reliability
- Every session becomes evidence you can audit
- Your SCI score rises with each verified session

Inspect the evidence behind a skill.
Move from unsupported claims to source-linked records that make screening, development and mobility conversations more informed.
- Assess candidates against verified peer session evidence
- Skill signal piped directly into your pipeline via API
- Webhooks, SDKs, and a developer-grade portal
- Replace unreliable screens with real proof records
Verification
Trust starts with being able to inspect the source.
Lemma keeps the relationship between a skill and its evidence visible. Verification status, source context, dates and ruleset information help a viewer understand what a record means.
- Source-linked evidenceEvery record names where it came from and who was involved.
- Clear verification stateA skill shows what has been checked, and what has not.
- Time and recency contextEvidence carries the date it was demonstrated, not just added.
- Versioned methodologyResults reference the ruleset version used to form them.
- Permissioned sharingYou choose the scope a viewer receives.
Example record
See it for yourself
Look at a real skill record before you build one.
Rather than quote people you cannot check, we would rather show the object. Open a skill record and follow it back to the evidence, the source and the criteria behind it.

Questions people ask first.
Read the methodologyA Skills Passport is a portable collection of skill records. Each record can include the evidence, source, context, criteria and verification information behind a skill.
Evidence can come from assessments, coursework, projects, teaching, peer activity, external artefacts and workplace contributions. Availability and verification depth depend on the source.
No. A CV summarises experience. A Skills Passport focuses on individual skills and the evidence that supports them. They can be used together.
Visibility follows the sharing scope you choose. A record you have not published stays private to you.
Yes. Lemma provides verification and status interfaces for approved integrations. The developer documentation covers the current API surface.
Give your skills somewhere to live.
Bring your evidence together and start building a Skills Passport that can grow with you.
