Anyone can label data.
Few can write the answer.
Expert-generated SFT, preference, critique, and reasoning data — built to your specification and delivered in the schema your pipeline expects.
From specification to schema-ready delivery.
Every item passes the same route — and the ones that don't hold up go back rather than through.

What we assess
Data types, generated to your specification.
Every dataset is produced by contributors qualified in the domain, then verified against your rubric and gold standards.
SFT datasets
Expert-written demonstrations that model the behaviour you want to teach.
Preference pairs
RLHF and RLAIF comparisons with the rationale behind each judgment attached.
Critique and rewrite
Structured critique of model output, paired with a corrected version.
Reasoning traces
Step-by-step solutions that expose the working, not just the answer.
Domain answer generation
Subject-matter responses in fields where correctness requires real expertise.
Output verification
Expert verification of model-generated candidates before they enter training.
How it runs
Built to your rubric, not a generic guideline.
We work from your specification and your gold standards, and we measure contributors against them continuously rather than once at onboarding.
Specification
We work from your rubric, schema, and gold standards — not a generic annotation guideline.
Qualified contributors
Domain experts are assessed against project-specific standards before any production work.
Multi-stage review
Independent review against your rubric and gold standards at every step.
Format delivery
Delivered in the schema and structure your training pipeline expects.
Who does the work
Written by people who know the subject.
Post-training data is only as good as the person who wrote it. We staff each dataset with contributors qualified in the relevant domain and measure them continuously against your standard.
- Software engineering
- Mathematics and formal reasoning
- Computer science and systems
- Finance and accounting
- Law and policy
- Medicine and science
- Languages and localisation
