ABOUT SEMCASTING
Pioneering Cookie-Free Identity Since Day One
 
Semcasting is the data-as-a-service company that pioneered cookieless identity resolution and secure first-party data onboarding. Our patented constellation matching technology delivers deterministic accuracy across every digital channel - without proprietary IDs or walled gardens.
 

Our North Star

“Marketing accountability requires identity transparency — knowing exactly who you matched, who you served, and who converted at the record level.”

WHAT WE BELIEVE

Our Values Drive Every Product Decision

Three principles guide how we build identity infrastructure for regulated industries. 

Privacy First

Every audience workflow is built for HIPAA, SOC 2, and HITRUST environments - not retrofitted afterward. Privacy is architecture, not policy.

Deterministic Identity

No probabilistic matching. No lookalikes. We use verified deterministic identifiers - homes, devices, NPI numbers - to find real people, not models of them.

Transparent Measurement

Every campaign reveals exactly who was matched, served, and converted. No black boxes. No platform-reported metrics. Real outcomes at the record level.
