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.

Decision intelligence that simulates how consumers actually choose
Governed self-service models grounded in behavioral-economics research capture the mechanics of consumer decision-making and return predictive and prescriptive analytics quickly.
Virtual consumers represent human values, perceptions and choice processes inside a parallel model of your market, so scenarios can be tested at market pace without real-world risk.
Explore alternative launches, price points, messages and investment levels side by side, spotting problems early and choosing a direction with evidence behind it.
A human-centric narrative layer traces results back to their drivers, which builds trust in the simulation and helps internal teams adopt what it recommends.
