Medical & Healthcare
MDs, RNs & clinical PhDs
Clinical-note QA, diagnosis reasoning, medical coding, radiology labels and HIPAA-aware red teaming.
Services
Expert-grade human data for frontier AI.
A vetted network of domain experts - MDs, JDs, CPAs, PhDs, professional engineers and native linguists - running on one infrastructure with versioned guidelines, golden-set benchmarking and live IAA dashboards.
Domain Expert Annotation
Frontier problems need credentialed reviewers.
When a task needs a licence, a clinical intuition or a decade of practice, we route it to experts who actually have it.
Legal & Compliance
JDs & practicing attorneys
Contract review, case-law reasoning, regulatory classification, policy red-teaming and jurisdiction-specific evaluation.
Finance & Accounting
CPAs, CFAs & analysts
Financial-document extraction, tax and audit reasoning, XBRL-style tagging and numerical QA on model outputs.
Science & Engineering
PhDs, PEs & senior engineers
STEM reasoning, coding at senior level, patents, mathematical proofs and technical documentation review.
Core Services
Nine data services. One infrastructure.
RLHF & Preference Data
Pairwise comparisons, rankings and multi-turn preference collection - reviewed by domain experts where the prompt demands it.
LLM Evaluation
Rubric-based scoring, factuality audits and red-team probing across reasoning, coding, math and safety - calibrated against a golden set.
NLP & Code Labeling
Span labeling, NER, intent classification, summarization QA, code review and dialogue rating with engineer-in-the-loop review.
Computer Vision Datasets
Bounding boxes, semantic and instance segmentation, keypoints and 3D/LiDAR cuboids on culturally-grounded imagery.
Speech & Audio Data
ASR transcription, speaker diarization, audio-event tagging and TTS voice rating across 40+ languages and dialects.
Video Annotation
Multi-object tracking, action and event segmentation, and content-moderation labels for long-form and short-form video.
Multilingual & Dialectal
Native speakers across 40+ African languages auditing translation quality with MQM error taxonomies.
Red Teaming & Safety
Adversarial probing by legal, medical and financial specialists using structured harm taxonomies.
Quality Assurance
Golden-set benchmarking, inter-annotator agreement (Cohen's κ, Krippendorff's α) and blind consensus review on every batch.
How we vet experts
A five-step gate before anyone touches your data.
Every expert is credential-checked, NDA-bound and calibrated against a golden set before production. Agreement is monitored batch-over-batch - reviewers who drift are off-boarded.
