What Gunbrain does

Most campaigns reach everyone on a site. Gunbrain reaches people based on what they have done. It finds the ArmanetIDs most likely to buy, click or sign up, and puts your budget there first. Less waste. Lower cost per customer.

It is the targeting Meta and Google are known for, built for the firearms industry, on data no one else has.

Every brand, side by side

Same publishers. Same six weeks. Only the audience changed.

Across all eight brands, the Gunbrain side drove 24% more conversions (475 vs. 384) on about half the budget ($10.7K vs. $20.8K), cutting cost per conversion from $54 to $23.
