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.
Long-horizon AI agents that run insurance and financial services work end to end
Long-horizon agents that work uninterrupted for hours or days, reasoning through evidence and risk rather than just surfacing a recommendation.
Officially oriented around carriers, financial institutions, TPAs, and lenders, with coverage across 16 lines of business including auto, property, travel, life, health, commercial, workers' comp, cyber, and mortgage.
Strata lets users ask in plain English to pull reports, query the agent fleet, change how agents behave, and even build and ship a brand-new agent for a workflow.
Agents run across the tools your teams already use, with no rip-and-replace and no forced migration to a new system of record.
