Prove the impact of every campaign.

Primer shows you which companies are visiting, proves lift with holdout groups,
and closes the mobile → desktop conversion gap.

Primer helped us box in Meta’s algorithm — and boost enterprise conversions by 37%.
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.
Our outreach is more efficient, as a result of the awareness built through integrated, cross-channel messaging to the same audience.
We saw across the board 67% more prospects involved in deals. And because of that, we saw 31% higher win rates on those 25% bigger deal sizes and 17% shorter sale cycles.
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.
People are actually mentioning our ads in sales conversations. That’s exactly what we wanted.
Primer really helped us unlock performance marketing. Once we started using it, our CPL decreased by 55% and our MQLs increased by 34%.
With other data enrichment tools, I’d get 30-40% match rates. With Primer, I got 90% on Facebook, LinkedIn and Instagram.
