About
A leading identity resolution and information services provider, operating as a TransUnion subsidiary with deep data assets spanning marketing, fraud, and communications intelligence
Neustar is an American technology company that provides real-time information and analytics across industries including risk, digital performance, defense, telecommunications, entertainment, and marketing. In the advertising space, Neustar serves major global brands with marketing intelligence aimed at driving more profitable programs and connected customer experiences, offering solutions built on its OneID identity system that enhance CRM and digital audiences, enable advanced segmentation and modeling, and deliver measurement and analytics tied to a persistent identity key. Its Neustar Optimizer platform is a closed-loop marketing optimization and consumer insights tool that allows marketers to measure all consumer activity and make real-time optimizations across marketing mix, media budget allocation, campaign and creative tactics, and audience segments. Neustar's Unified Measurement Solution spans Marketing Mix Modeling and multi-channel attribution, and was the first attribution service to unify broadcast radio — which reaches over 90 percent of Americans monthly — with all other channels into a single platform. Neustar also offers Fabrick, a marketing analytics solution for publishers that provides a better way to measure users across platforms and channels, with benefits including cookieless media addressability, protection of first-party subscriber data, and access to connections with premium buyers. In late 2021, TransUnion purchased Neustar's main business for $3.1 billion.
