Verified expert networkVerified at source

Know exactly who's training your model.

RLHF, evaluation, and multilingual data from verified professionals. Every expert's identity, employer, role, and seniority is verified at source — against systems of record, not resumes or self-attestation.

The difference

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, what they actually do, or how senior they are. We verify all four at source, against systems of record.

Capabilities

Everything a frontier lab feeds its models.

All capabilities
Preference data

RLHF & Preference Data

Pairwise judgments and reward signal from verified professionals in-domain — people whose role and seniority we verified at source, doing the work they're qualified to grade. Rationales documented, quality audited, identity never in question.

Demonstrations

SFT & Expert Demonstrations

Gold-standard task demonstrations authored by practitioners — diagnoses, briefs, repair procedures, financial analyses — with the reasoning models should absorb, from experts we can vouch for.

Measurement

Human Evaluation & Red-Teaming

Model report cards graded by domain experts with verified credentials: side-by-sides, capability probes, and adversarial passes — with confidence intervals, not anecdotes.

Languages

Multilingual & Native-Speaker Data

Native speakers whose fluency is verified at source — not a self-ticked checkbox on a marketplace form.

Professional domains

Licensed & Professional Experts

Doctors, nurses, lawyers, insurance and financial-sector specialists, IT professionals, project managers — matched to tasks by verified role and seniority, not resume titles.

Industrial & field

Trades & Industrial Expertise

Electricians, mechanics, CNC operators, aviation technicians, energy and agriculture specialists, defense-sector engineers — the technical and blue-collar depth most vendors can't reach through a sign-up form.

Domains

Deepest where wrong answers cost the most.

Why verification

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. We verify all four at source and attach that provenance to every unit of data you receive.

1

Identity

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

2

Employer

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

3

Role

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

4

Seniority

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

The expert network

From operating rooms to machine shops.

Join the network

Doctors, lawyers, and financial specialists — and the electricians, CNC operators, aviation technicians, and agronomists most vendors can't reach through a marketplace sign-up form.
