Who You're Reaching, Not Just a Device
Deterministic vs. Probabilistic: Why It Matters
Not all identity resolution is equal. Semcasting's deterministic approach delivers verified, one-to-one matches, not statistical guesses that erode as cookies disappear.
Ingest First-Party Data
Upload your CRM, email list, postal file, or device IDs. Semcasting accepts virtually every data format: hashed emails, MAIDs, postal addresses, log files, phone numbers, and IP addresses.
Deterministic Matching
Our patented constellation matching links your records to verified household and individual identities across 1.8 billion IP addresses, 800 million encrypted emails and over 450 million device identifiers.
Resolve to Digital lDs
Each matched record is mapped to persistent, platform-specific digital IDs — Trade Desk UIDs, Freewheel, OpenX, Index Exchange, Clearline and more — ready for immediate activation.
How Semcasting's Patented Matching Works
Unlike single-signal matching, Semcasting uses a "constellation" approach, dynamically combining multiple online and offline identifiers for the highest possible match rate and accuracy.
IP-to-Address Matching
Our core patented technology maps IP addresses and timestamps to verified physical addresses, linking digital activity to household modems with 98% accuracy. No cookies required.
Hashed Email Resolution
Match hashed email addresses from your CRM to digital IDs across 800 million encrypted email records. Deterministic, privacy-safe, fully opt-in compliant.
Cross-Device Identity
Link desktop, mobile, tablet, and CTV devices to a household and individuals at home or at work. Our 450 million opt-in device graph enables true people-based targeting..
B2B Firmographic Matching
Resolve business records to individual employees by company, role, title, and department. Deterministic B2B matching without relying on cookies.
Federated ID Architecture
Your first-party data never leaves your control. Matches locally, de-identifies in processing, syncs to platform-specific anonymous IDs. Data is never copied or stored.
Same-Day Resolution
Most providers take days or weeks. Semcasting resolves and activates audiences within 24–48 hours of receiving your data.
Built Privacy-Safe From the Ground Up
Semcasting's identity resolution is fully CCPA-compliant, NAI-certified, and designed with privacy-by-design principles, not patched on after the fact.
