The human data marketplace · now taking requests

Verified human data, sourced to order.

AI teams get custom datasets and expert data annotation. Experts find paid AI work in their field. Owners license their data on their own terms. Every item carries consent and proof of where it came from.

01Who it's for

A market for the data models can trust.

AI teams buy, experts make, owners license. We vet everyone who joins, match the right people to each request, and keep the proof that every item was made and shared with permission.

Data owners

Creators, studios, labs and companies list the data they hold, decide if and how AI may learn from it, and get paid when it does.

  • Your terms, your price
  • Consent recorded and enforced
  • Paid per licence

02Why it matters

The next leap in AI won't come from more scraped data. It will come from better data, made by experts, with permission and proof.

03How a request works

From a brief to a lasting relationship.

Most data vendors sell what they already have. We start from what you need, then go and find it, and we stay on as your needs change.

  1. Brief

    You tell us the capability you're training for, where your current data falls short, and the bar it has to clear. We turn that into a written spec: modality, domain, volume, acceptance criteria and licence.

    SpecSigned off before sourcing
    AcceptanceMeasurable, per item
    LicenceScope, term, exclusivity
  2. Source

    We match the brief to creators who already hold rights to suitable work, and to vetted domain experts who can create, label or grade what doesn't exist yet. You see samples before anything scales.

  3. Verify

    Every item is fingerprinted, checked for human origin and duplicates, screened for safety and personal data, reviewed by a second expert, and bound to its consent record and signed provenance.

  4. Deliver

    Data arrives licensed, documented and in the format your pipeline expects, with a signed receipt listing every item. Need more next month? Standing orders keep new, matching work flowing.

04Proof, not promises

Every item carries its own proof.

Verification isn't a badge we add at the end. It's a record built as each item moves through intake, review and delivery, and it travels with the data.

01Cryptographic identity

Exact and perceptual fingerprints find copies, crops and re-encodes.

02Signed provenance

An Ed25519-signed manifest, C2PA where the format allows, and a Bitcoin-anchored timestamp.

03Consent and licence

Releases, permissions and licence terms bound to the item, not a spreadsheet.

How verification works

Illustrative record. Every delivered item carries one.

05What we source

Any modality. One standard.

From teleoperation episodes to clinical reasoning, every kind of data goes through the same intake, the same checks and the same proof.

Robotics & embodied01

Teleoperation, manipulation and sensor data

Demonstrations from trained operators, synchronized video, proprioception and force, with task success reviewed by robotics specialists.

Audio & speech02

Voices, accents, music

Consented recordings with speaker releases, transcripts and expert phonetic labels.

Text & reasoning03

Expert-written and expert-graded

Reasoning traces, rubrics, preference pairs and evaluations written by people who practice the field.

Image04

Original photography and art

Camera originals with releases, human-made origin checks and dense captions.

3D & CAD05

Geometry and scans

Meshes, point clouds and drawings with units and measured-versus-modelled labels.

Video06

Footage with context

Egocentric, instructional and cinematic video with frame-level fingerprints and scene annotations.

Documents & structured07

Records that are safe to train on

Contracts, filings and tables with schema, personal-data scans and masking before anything ships.

06The expert network

Your expertise is the scarce input.

Frontier models are now limited less by compute than by judgement. We pay specialists premium rates to create, label and grade the data that teaches them.

07The difference

Built for the questions your counsel will ask.

Training data now gets audited by regulators, litigators and customers. Ours is built to hold up.

08Questions

Asked often.

Something else? Ask us directly.

What makes the data “verified”?

Each item is fingerprinted at intake, checked for human origin and duplicates, screened for safety and personal data, reviewed by a qualified expert, and tied to a consent record and a signed provenance manifest with an independent timestamp. You receive a receipt that lists every item by ID and hash.

Why is the marketplace private?

Quality and trust. Buyers, experts and creators are each approved before they join, and buyers see curated selections rather than an open catalogue. We make the introductions, so every relationship starts with the right people on both sides.

Can you source data that doesn't exist yet?

Yes, that's most requests. When the catalogue doesn't cover a brief, we commission it: experts create, label or grade new examples to your spec, and creators produce new work under a licence agreed up front.

Do you offer data annotation and labeling services?

Yes. We annotate data you supply or data we source for you: text, documents, images, video, audio and 3D. Specialist tasks go to credential-checked experts in the field, such as radiologists for imaging or attorneys for contracts, and every label records who made it, with a second expert reviewing an agreed share.

Who owns the data, and what can we do with it?

Creators keep ownership. You receive a written licence for the uses you need, from AI training to evaluation, with the term and exclusivity you choose. Exclusive licences close the work to other buyers.

How do experts get paid?

Experts are paid for approved work at rates set by the specialty and the task, with payouts made automatically through Stripe once identity and tax details are verified.

I'm an expert. How do I find paid work?

Browse open opportunities: paid, flexible gigs that each show their field, pay and time commitment. If nothing fits yet, apply to the expert network and we'll invite you when matching work opens.

Can I license data I own?

Yes. List it with a short description, who holds the rights and whether people in it have consented. A person reviews every listing, and you set the price and licence terms before anything is offered to a buyer.

Do you work with robotics companies?

Yes. We source teleoperation and manipulation demonstrations, egocentric video and sensor recordings from trained operators, with success labels reviewed by robotics specialists.
