Add precision to your retargeting

Blasting your retargeting to all your visitors doesn’t make sense. Optimize your campaigns (and ad budget) by only retargeting qualified traffic with highly tailored ads. Quality of views beats out quantity.

Starting sales conversations, earlier

See how Outreach uses Clearbit to boost marketing and sales efficiency and generate 2x as many qualified leads than generic retargeting.

Your customers, both anonymous and known, are talking to you through their interactions on your website. So don’t treat them just as a cookie or an impression. Understanding people and how they want to be treated will always prevail.
