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.
Turn site imagery into a living 3D record of your infrastructure
Convert field photography and aerial imagery into an interactive 3D model of towers, rigs and plants that anyone on the team can navigate from a browser.
Pin inspection findings to specific components and legs so a coating defect or corrosion spot is always tied to the exact asset location.
Give every component a dated baseline of its condition, then append inspection and maintenance events as they happen.
Follow a finding from the inspector's report through work orders to the crew that completed the fix, with exportable inspection and maintenance reports.
