Human-validated training data and evaluation services for frontier AI models
Chain-of-thought reasoning traces, SME-level RLHF, supervised fine-tuning demonstrations and adversarial red teaming for the most capable models.
Golden trajectories, RL environment design, failure-mode taxonomies and software-engineering-driven deep evaluation for autonomous agents.
Multilingual ASR and conversational speech data, expressive TTS annotation, vision-language model training data, video action labelling and voice-agent evaluation.
LiDAR point-cloud labeling, multi-camera sensor fusion, robot demonstration trajectories, world-model rollouts and embodied interaction logs.
Enterprise AI governance platform that turns policy into proof across the model lifecycle
Build a governed inventory of internally built and third-party AI systems so every model has an owner, a purpose and a documented risk profile.
Continuously monitor model behavior, run stress tests and surface drift or bias signals before they become audit findings.
Codify enterprise AI policies and controls once, then apply them consistently across underwriting, claims, risk and other functions.
Manage external AI risk inside existing third-party risk workflows, with visibility into what vendors provide and how it is used.
