Practice · Human data

Where expert judgment moves the metric.

Some data work survives crowd labor. The work that decides whether a model ships doesn't. We field specialists for the tasks where being right takes real expertise, and being wrong is expensive.

Engagement

Embed our people, or hand us the outcome. The bar doesn't change.

IEmbed

Experts in your pipeline.

Calibrated specialists placed directly into your pipeline, working in your tools, to your rubrics. Days to ramp, not the weeks a requisition takes. You direct the work; we stand behind the people who do it.

IIOwn

Delivery, end to end.

Hand us the workflow. We staff it, run it, and answer for the output against agreed service levels. One counterparty, not a roster to manage yourself.

CapacityBoth models flex with your release cycle. Scale the bench up for a push, back down between them, without losing continuity on the specialists who already know your domain.

Start small

The lowest-friction way in: a two-week data quality audit.

You hand us a sample of your labeled or preference data. Independent experts re-review it against your own rubrics, blind to the original judgments, and we report where quality is leaking, why, and what to change.
