Question: Is there a tool that allows for custom attribute assembly for targeted advertising?

If you're looking for a tool that lets you assemble custom attributes for targeted advertising, Dstillery is a good choice. The company creates data-driven custom audiences with AI technology. It offers three custom audience products and uses ID-free technology that gathers browsing behavior data to predict user behavior and target accordingly. Its Audience Brief Genius tool can select audiences with OpenAI technology and offer insights like audience overlap and rank, and website-based insights.

Another good option is Intent.ai. The company's machine learning technology processes technical logs to create detailed subscriber profiles that capture demographic information, interests, behaviors and habits. Intent.ai offers custom attribute assembly and a data privacy model that includes locality, minimization, anonymization and open APIs for data filtering. It's designed to protect data privacy but still offer accurate targeting for mobile carriers, so it's a good pick for telecom operators that want to create a new revenue stream without losing control over data.

Anonymised is another option. The cookieless data platform matches publishers with advertisers to improve marketing performance. It offers a persistent cross-publisher identifier for users who consent to data collection, lookalike predictions for those who don't consent, and custom interest and intent data for targeting across all browsers. Anonymised ensures GDPR compliance by using anonymized data and disclosing zero personal data, offering high-CPM audiences, custom segments and campaign effectiveness measurement.

Last, Proximic offers AI-powered contextual intelligence to boost audience engagement and monetization without using user identifiers. The company's technology includes options like predictive audiences, contextual intelligence and customizable segments. It works with a broad range of media sellers and offers privacy-centric inventory curation tools, making it a good choice for those who want to target audiences without relying on cookies.
