Common Questions About Our Platform

Everything you need to know about how Data, Identity Resolution, Activation, and Measurement work together at Semcasting.

What is deterministic identity resolution?

Deterministic identity resolution uses verified first-party signals — IP addresses, hashed emails, postal records, and device IDs — to match your data to real people with confirmed accuracy. Unlike probabilistic methods, deterministic resolution does not rely on statistical inference or third-party cookies. Semcasting's patented constellation matching combines multiple signals for 98% accuracy and 85%+ average match rates.
How does Semcasting activate audiences without cookies?
What is closed-loop measurement and how is it different?

Closed-loop measurement connects every ad impression back to a real business outcome — online conversion, in-store visit, or CRM match — using the same deterministic identity graph used for targeting. Most attribution relies on last-click cookies or modeled data that can't follow users across browsers or devices. Semcasting's approach is fully deterministic: every attribution is a verified identity match, not a statistical inference.
How long does it take to go from data to live campaign?
Is Semcasting's platform privacy-compliant?

Yes. Semcasting is SOC 2 Type II certified, CCPA-compliant, and a member of both NAI and DAA self-regulatory programs. Our federated ID architecture loads and matches first-party data locally, and user data is never copied, shared, or stored on Semcasting's servers after processing. Our data compilation practices are fully opt-in and regularly audited for compliance across healthcare (HIPAA-conscious), financial (GLBA), and political contexts.
