  1. 01

    Scope.

    We write the spec with your research team: modality, volume, quality bar, exclusivity.

  2. 02

    Source.

    We find the owners who hold it and negotiate the licence.

  3. 03

    Clear.

    Rights, consent and PII checks; deduplication against the public web; quality scoring.

  4. 04

    Deliver.

    To your storage, with a datasheet and a per-record provenance manifest.

Every record traces back to a signed licence.

  • Chain of title per record

    Every record maps to a signed supplier agreement and a buyer licence.

  • Consent for any personal data

    Rights and consent terms are reviewed before anything is listed.

  • PII removed before delivery

    De-identification runs inside the owner's environment, before export.

  • Contamination check

    Every dataset is checked against public benchmarks before it ships.

For data owners

Your archive is worth more than you think.

Publishers, archives, enterprises, labs and creators license data through Quarry. You keep ownership, set the terms, and get paid per licence.

  • Keep ownership

    You license access; the archive stays yours.

  • Set the terms

    Exclusive or not, permitted use, territory, term, and who's excluded.

  • Get paid

    A revenue share on every licence, on the schedule you sign.
