Have meaningful conversations that last a lifetime, across every device, channel and media format.

"Personalization" has come to mean everything that’s even remotely targeted or customized—leaving marketers disappointed by the results of inaccurate, ineffective "personalization solutions."

What marketers are really hoping for is one-to-one marketing at scale. This is far more specific—and far more challenging to achieve.

We define one-to-one marketing at scale as: Recognizing, reaching and staying connected to a sizable number of individuals whom you know a lot about, through meaningful, ongoing conversations, in real-time, and being able to learn and optimize as you go.

Conversant can help you achieve one-to-one marketing, with mastery of the four essentials:

Recognition & Reach

To launch a successful digital program, you must be able to recognize your customers across all their devices.

Our understanding of consumers is built from the anonymized transactional data (both online and off) of more than 4,000 brands. And the depth and breadth of our IDs continue to grow as we observe over 100+ billion online interactions every day, across every device and channel.

Matches only happen at cookie or segment level. And a broken chain of custody means a lot of data leakage.

User IDs come from third-party cookies and reach a tiny fraction of your target audience.

We have the industry’s largest reach of consumers at the person level, across all their devices.


Profiles are built only from emails and websites, not from offline CRM data—and the data doesn’t persist over time.

The focus is on just a single data point (recent items viewed, but not purchased, on one website) that disappears when the objective is complete.

We recognize online and offline activity—including 100B+ online actions per day, to build each profile across more than 7,000+ dimensions.


There’s typically no creative personalization. Most use automation and templates to customize just a few elements.

Ads are only personalized for the last item browsed, or some related products.

Our 1T+ daily real-time decisions are customized for each person, across unlimited factors in each ad.


Real-time optimization happens only at the segment level, not the person level. And insights only go to the campaign level.

Campaigns don’t drive long-term customer understanding. Reporting may show sales, but analysis shows that many are non-incremental.

We update our 160M+ consumer profiles in real time. And our clients have full visibility into their campaigns’ power.
