What Semcasting Identity Graph is
Semcasting Identity Graph is an API identity product for organizations that need to connect their first-party customer records to people, households, and devices. It uses deterministic matching to resolve identifiers such as email, postal address, device ID, IP address, hashed email, mobile ad ID, and CTV household identifiers into persistent profiles. Organizations can provide CRM files, email and postal lists, transaction records, website event data, phone numbers, MAIDs, and device IDs. Semcasting says the graph refreshes continuously as customer, device, and address information changes, and reports match rates of 85% or higher. The profiles can support targeting, suppression, attribution, and personalization across programmatic display, CTV, social, email, direct mail, and in-store channels. Semcasting describes connections to more than 40 DSPs and lists integrations including Google Ads, LinkedIn, Meta/Instagram, Pinterest, Reddit, TikTok, LiveRamp, Roku, StackAdapt, and The Trade Desk. The company says first-party data is matched locally in a clean room, de-identified during processing, and not shared, sold, or used to build third-party segments. Its stated graph scale includes 1.8 billion mapped IP addresses, 450 million devices, 800 million encrypted emails, and 167 million US households. Semcasting lists SOC 2 Type II certification, CCPA compliance, NAI membership and certification, and participation in the DAA self-regulatory program.
