Identity Graph — Built on Your Data
The Foundation of First-Party Data Strategy.
An identity graph is a database that links all known identifiers for a person or household — email, postal, device, IP, and behavioral signals — into a single, unified customer profile. It's what makes cookieless targeting and measurement possible.
Without an identity graph, every channel sees a different version of the same customer. With one, you have a single persistent view that powers targeting, suppression, attribution, and personalization across every touchpoint, owned entirely by your organization.
Identity Graph — Defined
A persistent database that resolves multiple identifiers — email, postal address, device ID, IP address, hashed email, mobile ad ID — to a single unified customer profile per person or household, using deterministic matching rather than probabilistic modeling.
Unified Customer Profiles
Link all your customer touchpoints — website visits, CRM records, purchase history, ad exposures — into a single persistent profile per person or household. Eliminate duplicate counting and gaps in your audience view.
Always-On Syncing
Your identity graph continuously updates as new data flows in: new customers, device changes, address updates. No manual refreshes required. Audiences stay current without re-onboarding your CRM every campaign.
Private Graph Architecture
Semcasting builds your identity graph inside a privacy-safe clean room. Your first-party data is matched locally and de-identified during processing, never shared, sold, or used to build third-party segments.
Omnichannel Reach
Your identity graph powers activation across every channel: programmatic display, CTV, social, email, direct mail, and in-store. One graph, infinite channel flexibility. No re-segmentation required per platform.
The Semcasting Identity Universe
Semcasting's national identity infrastructure is what powers your custom graph, connecting your records to the largest deterministic identity network in the US.
How Semcasting Builds Your Identity Graph
Four steps from raw first-party data to a live, always-on identity graph powering every channel.
Ingest First-Party Data
Upload your CRM, email list, postal file, transaction records, or website event data. Semcasting accepts virtually every format: hashed emails, MAIDs, postal addresses, phone numbers, device IDs.
Deterministic Resolution
Every record is matched to Semcasting's national identity infrastructure using IP-to-address constellation matching, linking your data to verified individuals, households, and devices with 85%+ match rates.
Graph Construction
Matched records are unified into persistent customer profiles, linking every known identifier for each person or household into a single graph node with a permanent Semcasting ID.
Activation & Attribution
Your identity graph is live, powering omnichannel targeting across 40+ DSPs, enabling closed-loop attribution, and continuously updating as new first-party data flows in.
Built for Organizations Ready to Own Their Audience
An identity graph is the foundation of any serious first-party data strategy across every industry and organization type.
First-Party Data Owners
Build a persistent audience asset that outlives cookie deprecation, platform changes, and privacy regulations, owned entirely by your organization. Stop depending on third-party data that disappears overnight.
