Our outreach is more efficient, as a result of the awareness built through integrated, cross-channel messaging to the same audience.
With other data enrichment tools, I’d get 30-40% match rates. With Primer, I got 90% on Facebook, LinkedIn and Instagram.
Primer really helped us unlock performance marketing. Once we started using it, our CPL decreased by 55% and our MQLs increased by 34%.
Getting a fresh audience was a major challenge for us. Primer solved that.
Finding quality leads aligned with our ICP has always been a challenge — Primer’s recent improvements have unlocked significant performance efficiency improvements, as well as scale.
People are actually mentioning our ads in sales conversations. That’s exactly what we wanted.
We pivoted to a new vertical in five minutes. We cloned an existing audience, filtered by vertical, and instantly had a campaign-ready list of 75,000 decision-makers.

Prove your ads are working —  beyond first-touch, last-touch.
