A resume is a claim. A system of record is a fact.

Most AI-training talent is vetted with a resume, a LinkedIn profile, and a contractor agreement — none of which confirms who someone actually is, who they work for, or how senior they are. Rainbow verifies each expert's identity, employer, role, and seniority at source, against systems of record.

What we verify

Four properties, established before an expert touches your data — and attached as provenance to every unit of work:

01

Identity

The person doing the work is who they claim to be — confirmed against authoritative records, not a profile photo.

02

Employer

Where they actually work — verified at source, not read off a resume.

03

Role

What they actually do — the real function, not the title typed into a form.

04

Seniority

How senior they actually are — established against systems of record, not self-attestation.

Provenance is the weak link. We made it the product.

In every human-data pipeline, the hardest thing to confirm is who actually did the work. Resumes, marketplace profiles, and contractor sign-ups don't establish identity, employer, role, or seniority.

A qualification test verifies a session, not a person. A profile verifies nothing at all. Verification at source closes that gap — and the provenance ships with the data, unit by unit.

We publish what is verified and to what standard. The mechanics stay ours.

The standard

Verification happens at source, against systems of record — not by collecting documents from the expert and taking them at face value.

Every engagement ships with provenance: which verified expert did the work, under which verified role and seniority, with the QA trail behind it.

How an engagement runs

01

Define

Domains, languages, volumes, and quality bar — scoped with our research team.

02

Match

We staff from verified experts: role, seniority, language, and track record.

03

Verify

Every expert is verified at source before their first task — identity, employer, role, seniority.

04

Deliver & audit

Stable teams, documented QA, and provenance you can trace to a named, verified professional — for every unit of data.
