How Worth works

One consented pipe, supply to model.

A matching engine routes your request to verified, consenting contributors. Every hop is signed, so what reaches your model is traceable end to end.

The problem

Your training data has a trust problem.

Quality is collapsing and provenance is a black box. Both are now legal exposure, not just a quality issue.

The pain
RLHF quality is degrading: bot-polluted panels, fake credentials, "experts" who are not.
Worth
Every contributor is verification-gated: license, employer, tenure. You buy a verified nurse or staff engineer, not a guess.
The pain
Provenance is opaque. You cannot prove where a training example came from or whether anyone agreed.
Worth
Every datum carries a signed, per-use consent record. A clean chain of consent for the EU AI Act, FDA RWE, and your legal team.
The pain
Sourcing rare experts is slow: recruiters, spreadsheets, weeks of back and forth.
Worth
An agent matches your request to qualified, consented supply and returns it in days. Post a request, we fill it.
The pain
Regulated data (clinical, patient cohorts) is legally radioactive to source directly.
Worth
We broker consented cohort data unions. Consent and de-identification are handled. You get usable evidence without the liability.
What you can buy

Four supply types, one consented pipe.

Start where demand is proven, expand into the regulated, higher-value supply as you go.

Most common

Verified-expert RLHF

Preference labels, evaluations, and "what would a senior X say", from credential-verified professionals: nurses, MDs, staff engineers, attorneys, native-language experts.

e.g. medical-dialogue RLHF from verified clinicians
Available now

Expert reasoning traces

Annotated decision and debugging traces from senior practitioners. The highest-demand training signal for reasoning and coding models.

e.g. distributed-systems debugging traces
Wave 2

Consented data licenses

Scoped, time-boxed, revocable access to real longitudinal data: sleep and HRV, glucose, code repos, clinical outcomes. Anonymized to your spec.

e.g. consented CGM plus training-load study data
Wave 3

Regulated cohort evidence

Patient-data-union licenses (T1D, oncology, and more) with consent, de-identification, and ethics framing handled. Real-world evidence without the sourcing liability.

e.g. T1D cohort RWE for a Phase III study
Why revocable consent helps you

Per-use consent is a compliance feature, not a risk.

The instinct is "revocable means I lose the data after I trained on it." It does not work that way, and it protects you.

BLOCK 01

Contributor grants, scoped

A verified expert consents to this exact request. The grant is recorded and signed.

0x4a…c9 · signed
BLOCK 02

You license and pay

You receive the supply and a per-example consent receipt. Your trained-model use is permanent and safe.

0x7f…1e · signed
BLOCK 03

Revocation is forward-only

If a contributor revokes, it ends future access. It never claws back a license you already paid for and used within scope.

forward only, never retroactive

Audit-ready by default

When a regulator, a journalist, or opposing counsel asks "where did this come from and did the person agree", you have a cryptographic answer. Cheaper than an indemnity.

Built for the EU AI Act and FDA RWE

A clean chain of consent and provenance is exactly what high-risk training and real-world-evidence submissions now require. Scraped or pooled-token data cannot produce it.

The trade you actually make

You give up a little perpetual-ownership theater for real legal defensibility. For anyone training on health, code, or person-level data, that is the better trade.

How a pilot works

Small, fast, designed to prove it.

One batch against a real request of yours. Built to prove quality and provenance, not to lock you in.

1

You define the spec

Your request, your acceptance bar, the exact expertise and data scope you need.

2

We deliver, consented

Verified supply matched and returned in days, each contribution traceable with a signed consent receipt.

3

You pay on delivery

Pay for what meets your bar. Small fixed batch, no long-term commitment.

Verified supply

Every contributor is gated.

No open panel, no bots, no unverified credentials. Most applicants never reach your batch. The badge a contributor carries is the credential you are paying for.

Credential verification

License, employer, and tenure checked before a contributor can supply.

Human, not bot

Verified-human supply only. No survey farms, no synthetic padding.

Scoped consent per request

Each grant is specific to your batch. Nothing is reused or resold.
