Copula Fellows · Expert Network
Turn frontline expertise into model capability.
Copula Fellows brings together people who have done the work themselves. We turn their workflows, judgment, and craft into rigorous training tasks, evaluation criteria, and environments for frontier models.

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.
Select a field to see who we work with, their expertise, and the data they help us build.

Financial reasoning evaluation, content understanding, prompt generation, and model preference ranking.
