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.
Behavior-based consumer segmentation for retail marketers
Every U.S. household is classified into 17 high-level groups and 80 behavioral segments built from demographics, social media activity, mobile movement data, and credit card transactions.
Upload CRM contact lists or a store visitation report, or draw a polygon, to see which segments drive the most value or visit a location most — typically in minutes.
Compare your brand against competitors by segment and track how much each segment spends on different brands over time, using insights from 100M+ credit card transactions.
Export top segments for targeting across Meta, TikTok, Google, Snapchat, X, programmatic platforms, and direct mail, or enrich your CRM with demographic and segment codes.
