AI overview

Updated

Symitri, Inc. builds an integrated privacy firewall and real-time data cleanroom for open-web advertising. Its PRISM AI platform lets advertisers and publishers match and activate their own first-party data for deterministic targeting, measurement and attribution without exposing personal or pseudonymous identifiers in the programmatic bidstream. The company raised a $5M seed round from KB Partners, AperiamVentures and Trajectory Ventures alongside media-industry angels, and acquired TRUSTX, the cooperative programmatic marketplace launched by Digital Content Next and roughly 30 premium publishers. It is led by CEO and co-founder Bill Wheaton, previously EVP and chief strategy officer at Akamai.

What sets it apart

Combines a privacy firewall and a real-time data cleanroom in one system, so buyers get deterministic person-level targeting, frequency capping and attribution across the open web while no party has to hand over or expose the data it owns.

  • Real-time audience segment updates driven by individual actions
  • Zero-latency co-located server infrastructure
