Track, evaluate, and ship AI models and agents in one connected environment.
Log metrics, losses, and media from training runs and compare them side by side in interactive charts to spot what actually improves your model.
Run automated hyperparameter sweeps and visualize parameter importance so you can converge on better configurations faster.
Version datasets and model artifacts, track lineage, and promote models through a registry from training to production.
Build, log, and evaluate LLM prompts and applications, with tracing and evaluation tools grouped under an LLMOps workflow.

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.
