How it works

Four steps from raw data to a checked dataset. The first two run today. The last two start with our first pilot projects.

The four steps

1Ingest and redact

Your data arrives encrypted. PII redaction removes personal data, and access is limited to the people on your project.

Liveingest

Encryption, redaction and access controls run today.

2Pre-label

Self-hosted open-weights models fill in a first pass of labels: Segment Anything for images and video frames, domain-tuned LLMs for text.

Livepre_label

The pre-labelling engine runs today.

3Expert review

Subject-matter experts check and correct each pre-label. Ambiguous items go to several reviewers who cannot see each other’s answers.

Nextsme_review

Starts with the first pilot projects.

4Agreement check and delivery

We measure agreement between reviewers with Fleiss’ kappa and Cohen’s kappa, send disputed items back for another round, then deliver the dataset.

Planned for the first pilot projects.

How much the models do

70–80%

of labels pre-filled by models before expert review

Design target, not a measured result. Source needed: this figure comes from our internal business plan and has not yet been measured on a client project.
