Spatial.ai

Behavior-based consumer segmentation for retail marketers

PersonaLive behavioral segments

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.

Segment your own data fast

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.

Market share and spend analysis

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.

Cross-channel audience activation

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.

Strengths & Pros

+Behavioral segmentation combining social, mobile, and transaction data adds context that demographics alone miss
+Self-serve segmentation from CRM files or visitation data delivers answers within minutes
+Audiences export to every major ad channel plus direct mail from one platform
+

Transparent published pricing with 90-day opt-out and multiple case studies from real brands

Limitations

–Coverage is limited to U.S. households, so non-U.S. brands are not served
–Plans start at $500/month and contacts or locations are billed separately, which is steep for small retailers
–Advanced competitive spend analysis requires the top Strategist tier
