Human data for frontier AI
The world’s leading AI models are built on more than algorithms, they’re built on human expertise. We deliver the expert-validated data that trains frontier models, ensuring AI systems understand nuance, context, and complexity at scale.
Data products to build foundational AI
Six specialised capabilities, each purpose-built for a critical dimension of modern AI development.
Frontier Alignment
CoT reasoning traces, SME RLHF, SFT demonstrations and adversarial red teaming for the world’s most capable models.
Agentic AI
Golden trajectories, RL environment design, failure mode taxonomy and SWE-driven deep evaluation for autonomous agents.
Multimodal and Speech AI
Multilingual ASR and conversational speech corpora, expressive TTS annotation, VLM training data, video action labelling and voice-agent evaluation for models that hear, see and speak.
Physical AI
LiDAR point cloud annotation, multi-camera sensor fusion, robot demonstration trajectories, world model rollouts and embodied interaction logs for AI systems operating in unstructured physical environments.
Model Integrity
Hallucination benchmarking, regulatory audits, bias detection and continuous monitoring to ensure your models are trusted.
Research Services
Context engineering, calibrated LLM-as-a-judge deployment, synthetic data generation and custom benchmarking for teams extending their research capacity.
