We build the human pipeline behind the world's best models.
Frontier AI is bottlenecked by data quality, not compute. We give labs a high-trust human layer — for evaluation, authoring, safety, and methodology — calibrated to research-grade rigor.
Preference & rating at scale
Pairwise comparisons, Likert scoring, rubric-based grading, and continuous preference streams for RLHF/DPO pipelines. Calibrated cohorts with κ ≥ 0.85.
- Pairwise & N-way comparison
- Rubric & Likert grading
- Continuous preference streams
- Inter-rater calibration reports
Expert reference data
Vetted domain experts — MDs, lawyers, engineers, PhDs — produce gold-standard answers, chain-of-thought traces, and SFT corpora in the domains where generic crowds fall apart.
- Domain-expert gold sets
- Long-form chain-of-thought
- Multi-turn dialogue scripts
- Rejection sampling labels
Red-teaming & policy audits
Trained adversarial reviewers probe for jailbreaks, harmful outputs, and policy violations. Full chain-of-evidence reports with reproducible attack vectors.
- Jailbreak probing
- Policy compliance audits
- CBRN & high-risk evaluations
- Threat-model design
Agentic & tool-use evals
Multi-step task scaffolding, trajectory grading, and tool-use evaluation for browsing, coding, and planning agents. We design the eval — and the rubric.
- Task scaffolding
- Trajectory grading
- Browser/code/CLI evals
- Sub-goal decomposition
Rubrics & taxonomies
Senior reviewers co-design the rubric, taxonomy, and gold-set sampling methodology that make your evals reproducible — and defensible.
- Custom rubric design
- Taxonomy development
- Gold-set sampling
- Calibration playbooks
Multilingual & multicultural
Native speakers across 40+ languages, including low-resource locales. Translation QA, cultural nuance review, and globalization-ready training data.
- 40+ languages, native quality
- Low-resource locale coverage
- Cultural sensitivity review
- Translation QA pipelines
Vetted expertise across every domain that matters
From frontier sciences to creative work, our talent network combines deep specialization with the writing chops to teach a model.
Research-grade rigor, every project.
Quality at scale isn't a slogan — it's a stack. Every cohort runs through structured calibration, blind gold checks, senior review, and statistical agreement tracking. You get the data and the methodology behind it.
