Three problems. One graph.
Publishers today face too much anonymous traffic, too little first-party audience data, and increasing pressure to grow revenue. Retention.com solves all three - turning anonymous visitors into known audiences, enriching audience intelligence, and creating new monetization opportunities across subscriptions, advertising, and programmatic channels.
Anonymous traffic and little first-party data
Most visitors are unrecognizable and your known audience lacks the attributes, intent, and behavioural signals needed to monetize effectively.
Declining traffic
Google Zero and AI and algorithm changes are drastically decreasing publisher site traffic and it's only going to get worse.
Pressure to grow revenue
New routes to monetization across subs, direct sales, and the bidstream.
The Industry's Most Complete Identity Graph
Our identity graph is built differently. Rather than relying on a single data provider, we combine a proprietary identity graph with a waterfall of best-in-class identity partners, ensuring maximum match rates and coverage across devices, channels, and environments.
This multi-source approach gives publishers access to over 250 million consumer identities, enriched by the industry's largest B2B dataset, creating a unique bridge between consumer and professional audiences.
The result is a more complete, accurate, and resilient identity solution that consistently outperforms single-source graphs delivering higher addressability, stronger audience intelligence, and greater monetization opportunities.
