AdTheorent Recognized for Programmatic Marketing Innovation in 2021 For Second Consecutive Year in MarTech Breakthrough Awards Program

Company recognized for its advanced machine learning capabilities and privacy-forward approach

NEW YORK., August 12, 2021 – AdTheorent, Inc., a programmatic digital advertising leader using advanced machine learning technology and solutions to deliver real-world value for advertisers and marketers, today announced that it has been selected as the winner of the “Programmatic Marketing Innovation” award in the MarTech Breakthrough Awards program conducted by MarTech Breakthrough, a leading market intelligence organization that recognizes the top companies, technologies and products in the global marketing, sales and advertising technology industry today.

AdTheorent's privacy-forward programmatic marketing platform uses market-leading data science and machine learning (ML) capabilities to deliver client-specific business outcomes for top brands. AdTheorent’s proprietary suite of tools and methodologies maximize campaign performance and drive superior ROI for advertisers.

Operating at massive scale, AdTheorent’s platform optimizes ad targeting by evaluating and assigning predictive scores to more than 87 billion impressions daily, bidding on less than .01% of impressions scored. AdTheorent’s data scientists have deep experience using ML tools such as Python, R., Scala and Spark to build and manage more than 1,000 individual ML models at any given moment. For each campaign, AdTheorent’s data scientists build and deploy into AdTheorent’s platform custom ML models tailored to drive business goals designated by customers.

“AdTheorent’s Predictive Advertising approach operationalizes ML models and predictive decisioning as part of its core bidding framework, using custom ML models to reach consumers with the highest likelihood of completing advertiser-specific outcomes without relying on user-specific personal profiles and individualized data,” said Jim Lawson, CEO of AdTheorent. “AdTheorent’s privacy-forward approach is well-suited for the future as individual user identifiers such as cookies and device IDs become less available for advertisers. We are grateful to be honored again by MarTech Breakthrough for our innovation and achievement in programmatic advertising.”

The mission of the MarTech Breakthrough Awards is to honor excellence and recognize the innovation, hard work and success in a range of marketing, sales and advertising technology related categories, including marketing automation, market research and customer experience, AdTech, SalesTech, marketing analytics, content and social marketing, mobile marketing and many more. This year’s program attracted more than 2,850 nominations from over 17 different countries throughout the world.

“Targeting digital ads programmatically without relying on user-specific personal profiles and individualized data is only truly possible with advanced machine learning. AdTheorent's privacy-forward platform delivers on this potential, changing what digital ad targeting can be.” said James Johnson, Managing Director at MarTech Breakthrough. “AdTheorent’s machine learning platform is a ‘breakthrough’ system in the advertising market today and we are thrilled to recognize them this year with our ‘Programmatic Marketing Innovation’ award.”
