Experts
High-quality data starts with the right experts.
Copula’s data is only as good as the people behind it. We build a vetted network of domain experts and turn their judgment into training and evaluation data that frontier labs can trust.
Why experts
Frontier models need real expertise — not commodity labels.
The ceiling is expert work
General reasoning is largely solved. The remaining gap is deep vertical expertise — the tasks only experienced professionals get right.
Annotators can’t close it
Standard annotation pipelines can’t produce expert-grade signal, because the annotators have never done the work themselves.
Judgment, made legible
We capture how experts actually reason — evidence standards, edge cases, tacit rules — and turn it into structured, auditable tasks.
The network
The best minds across every high-value field.
